What This Motor Represents in the Lineup

The Mitsubishi HC-SFS153 is the third step in the HC-SFS 3000 rpm compact family — above the 1kW HC-SFS103, below the 2kW HC-SFS203, and sharing the same 130 × 130 mm flange with both. At 1.5kW and 3,000 rpm, it produces 4.78 Nm of continuous torque with 14.3 Nm available for acceleration — a combination that sits squarely in the working range of a broad class of light-to-medium industrial servo axes that need speed without sacrificing meaningful torque capacity.

What makes the HC-SFS153 more than just a number between two other models is the amplifier pairing. Both the HC-SFS153 and the HC-SFS203 (2kW) use the MR-J2S-200 amplifier. Same mounting interface, same amplifier, different motor performance. This means a machine frame designed around the HC-SFS153 can accept the HC-SFS203 as a capacity upgrade with no mechanical or electrical panel changes — only an amplifier parameter update. That design flexibility is useful at the specification stage and even more useful when a machine needs more axis torque after it enters production.

Behind the shaft, the J2-Super platform delivers: 17-bit serial absolute encoder at 131,072 ppr, multi-turn absolute position backed by the A6BAT battery in the amplifier, real-time auto-tuning, and adaptive vibration suppression. Straight shaft, no brake — the clean, uncomplicated configuration for horizontal and symmetrically loaded axes that make up the majority of the applications this motor serves.

Technical Specifications

4.78 Nm at 3000 rpm: Reading the Operating Point

The torque-speed operating point of the HC-SFS153 deserves some direct attention, because it is where axis sizing decisions get made and where mismatches between motor and application show up most clearly in production.

Four point seven eight Newton-metres of continuous torque is a genuinely useful sustained force capacity at this compact frame size. It is enough to drive a 5mm pitch ball screw against moderate resistance at practical feed rates, sustain constant web tension on a light winding drive across a useful roll diameter range, power a timing belt primary drive on a fast-cycling assembly machine axis, or maintain the feed force on a light-duty material feed mechanism throughout a production cycle. It is not unlimited — axes that regularly demand more than 4.78 Nm continuously will accumulate thermal load until the electronic overload alarm trips — but within its envelope it is solid and reliable.

The 14.3 Nm peak is where positioning performance lives. At three times the continuous rating, this transient torque is available for the acceleration and deceleration phases of each move. A light-load axis completing rapid point-to-point moves draws on 14.3 Nm to ramp velocity up and down, spends most of the cycle at or below the continuous rating during constant-velocity motion, and the thermal model in the MR-J2S-200 handles the duty cycle without complaint.

The 3,000 rpm rated speed is the other half of the design equation. At rated speed with a 10mm pitch ball screw coupled directly, this motor drives a linear axis at 30 m/min. For CNC auxiliary axes, that is comfortable rapid traverse speed without any reduction stage between motor and screw. For belt-coupled applications, a modest 1.5:1 to 2:1 reduction brings the working speed down to a mechanically appropriate range while multiplying the available torque — a common design approach for axes where the motor mounts offset from the driven shaft.

The maximum speed of 4,500 rpm extends the operating range above rated speed in the constant-power region. Above 3,000 rpm, available torque decreases as speed increases. This region is useful for rapid traversal on light-load axes where speed is needed and the torque demand is well below the rated figure.

Where the HC-SFS153 Fits Between the 103 and the 203

All three motors — HC-SFS103, HC-SFS153, and HC-SFS203 — share the 130 × 130 mm flange, the 17-bit J2-Super encoder, and IP65 protection. A machine designed around any one of them fits all three mechanically without modification. But they are not interchangeable from the amplifier's perspective, and understanding the full picture is useful.

The step from the HC-SFS103 to the HC-SFS153 means changing the amplifier class — from MR-J2S-100 to MR-J2S-200. The motor mounting is unchanged, but the amplifier changes. The step from the HC-SFS153 to the HC-SFS203, on the other hand, uses the same MR-J2S-200 amplifier. Only the motor changes. This asymmetry matters for machine design: once the panel is built around an MR-J2S-200, the motor can be upgraded from HC-SFS153 to HC-SFS203 without touching the panel.

Why does the 1.5kW motor at 3000 rpm use the 2kW class amplifier? The current demand of a 1.5kW motor at 3000 rpm exceeds what the MR-J2S-100 is rated to supply. Mitsubishi's motor-amplifier compatibility tables confirm MR-J2S-200 for both HC-SFS153 and HC-SFS203 at 3000 rpm — the amplifier class is determined by the motor's current draw at its operating point, not purely by its nameplate wattage.

Straight Shaft, No Brake: The Clean Default

The HC-SFS153's straight shaft and no-brake configuration represents the default for well-designed horizontal servo axes at this capacity, and the case for it is straightforward.

On the shaft: At 4.78 Nm rated and 14.3 Nm peak, the coupling interface requirements are moderate. Precision servo couplings — bellows couplings, jaw couplings, disc couplings — handle this range cleanly when sized to the peak torque figure rather than the continuous rating. A coupling selected at rated torque is marginal during every acceleration transient; one selected at 14.3 Nm peak with a modest service factor handles the full operating range.

The straight shaft works for every common coupling type. Timing belt primary drives using a split-hub pulley. Ball-screw coupling through a flexible disc coupling. Direct coupling to a gearbox input. On applications where the driven component needs a keyed bore — a gear hub, sprocket, or custom pulley — the HC-SFS153K (keyed shaft, no brake) carries identical performance specifications and uses the same MR-J2S-200 amplifier. The shaft type changes nothing about the motor's electrical or dynamic behaviour.

On the brake: Servo lock through the MR-J2S-200's closed position loop is entirely reliable for horizontal axes with no gravitational load component acting along the shaft rotation direction. The 17-bit encoder monitors shaft angle continuously; the amplifier supplies corrective current to hold zero following error. For these axes, adding a brake means adding a 24V circuit, a relay, surge suppression, MBR interlock logic, and a brake disc on the maintenance schedule — for no functional return.

Apply the test deliberately to each axis: if servo current drops to zero unexpectedly, does the load move? On horizontal mechanisms and symmetrically loaded rotary axes, the answer is no. On vertical axes and inclined feeds, the answer is yes — and those applications belong to the HC-SFS153B (straight shaft, spring-applied brake) or HC-SFS153BK (keyed shaft, spring-applied brake). Getting this distinction right across all axes in a machine produces a cleaner, lighter, and simpler design.

17-Bit Encoder Performance at 1.5kW, 3000 rpm

The encoder on the HC-SFS153 is the same 17-bit serial absolute unit across the entire HC-SFS J2-Super range. One hundred and thirty-one thousand and seventy-two discrete angular positions per shaft revolution, with a multi-turn absolute counter backed by the A6BAT battery in the MR-J2S-200 amplifier.

At 3,000 rpm on a 1.5kW axis, the encoder's contribution shows up in two places that matter most.

Velocity loop quality at rated speed. At 3,000 rpm — 50 shaft revolutions per second — the velocity feedback loop needs fine angular resolution to compute accurate instantaneous velocity. At 131,072 counts per revolution, the control algorithm has more than enough resolution to produce smooth constant-velocity operation with low ripple at any point in the speed range, including the low-speed creep velocities used during positioning approach and dwell. The contrast with a 14-bit (16,384 ppr) predecessor is most visible at low shaft speeds, where the HC-SFS153's finer count granularity produces noticeably smoother torque output.

Absolute position through power events. When the machine stops — planned or not — the encoder retains the exact shaft angle and accumulated turn count in memory. On restart, the MR-J2S-200 reads the absolute position without any shaft movement required. For axes on production machines that cycle power frequently, or machines where a mid-cycle stop might leave the axis at any position in its travel range, the absolute position capability eliminates homing routines and reduces restart time to the minimum.

Battery maintenance. The A6BAT is in the MR-J2S-200 amplifier, not in the motor. Replace it at the first low-battery alarm from the amplifier. A depleted battery resets the multi-turn counter and requires a reference-return cycle on the next startup. Treating the low-battery alarm as an immediate maintenance item — not something to defer to the next scheduled stop — prevents this from becoming an unplanned production interruption.

Compatible Amplifiers

The HC-SFS153 pairs with the MR-J2S-200 amplifier family — the 2kW J2-Super platform. All three interface variants are available:

MR-J2S-200A accepts pulse-train position commands from CNC controllers and PLCs, plus analog speed and torque references. All control modes — position, speed, torque, and switched combinations — are available. RS-232C connects to MR Configurator for commissioning and diagnostic monitoring. For the majority of machine tool auxiliary axes and general industrial automation applications where the command source is an external controller, this is the standard choice.

MR-J2S-200B connects to Mitsubishi A-series and Q-series motion controllers via SSCNET fiber-optic serial bus. All axis commands, encoder feedback, alarm data, and monitoring signals travel over the fiber link. For coordinated multi-axis machines — axes that must move in synchronised relationship with other axes under a motion controller, whether for geometric contouring, electronic gearing, or synchronised transfer operations — the SSCNET bus provides real-time axis coupling that pulse and analog interfaces cannot deliver.

MR-J2S-200CP provides built-in single-axis positioning with up to 31 stored point-table positions, activated by digital I/O or CC-Link network command. For standalone indexed or point-to-point positioning axes that do not require coordination with other axes, the CP eliminates the cost of a dedicated motion controller. Register control axes, simple indexed feeds, and standalone transfer mechanisms with defined position sets are natural applications.

Compatibility notes. The HC-SFS153 requires an MR-J2S-200 amplifier. It is not compatible with first-generation MR-J2-200 amplifiers, which cannot read the 17-bit J2-Super encoder serial protocol. For machines running original MR-J2-200 hardware, the HC-SF153 (same mechanical specification, 14-bit encoder) is the correct motor. Not compatible with MR-J3 or MR-J4 amplifiers without a renewal adapter kit.

HC-SFS 3000 rpm Compact Family: Where the 153 Sits

The HC-SFS153 is the third capacity step in the HC-SFS 3000 rpm compact range and one of two motors on this flange that use the MR-J2S-200 amplifier. Step above it to the HC-SFS203 and the mounting does not change. Step above the HC-SFS203 to the HC-SFS353 and the flange grows to 176 × 176 mm.

Every capacity in the HC-SFS 3000 rpm family comes in four shaft-and-brake configurations: straight shaft (HC-SFS153), straight shaft with brake (HC-SFS153B), keyed shaft (HC-SFS153K), and keyed shaft with brake (HC-SFS153BK). All four use the MR-J2S-200 amplifier.

Typical Applications

High-speed CNC auxiliary axis drives. Pallet changer rotation axes, rotary tool magazine drives, and tool changer arm travel drives on CNC machining centres and turning centres. The 3,000 rpm rated speed enables fast magazine indexing and rapid tool change arm traversal; the compact 130 × 130 mm frame fits the physical constraints of compact tool magazine and ATC mechanism designs.

Primary drives on small-format packaging and labelling machines. Film pull drives, register control axes, and product spacing mechanisms on intermittent-motion packaging equipment. The combination of 4.78 Nm sustained torque for maintaining register under load, 14.3 Nm peak for rapid acceleration during indexed motion, and the 17-bit encoder for precise position feedback suits these high-cycle-rate applications well.

Conveyor and transfer axis drives on assembly equipment. Servo-driven conveyor sections, part transfer slides, and indexing mechanisms on compact automated assembly and test equipment. The 3,000 rpm operating point with direct or belt-coupled drives enables practical traversal speeds; the compact frame suits assembly machine structural geometries.

Web tension and dancer arm controls on converting machines. Tension control drives on slitting, laminating, and coating lines where the motor runs in torque control mode to maintain constant web tension across a changing roll diameter. The 4.78 Nm continuous torque in torque control mode covers the working tension range on light-duty converting stations with appropriate margin.

Textile machine secondary axis drives. Feed roll drives, yarn tension axes, and warp beam let-off drives on knitting and weaving machinery where precise speed and tension control at moderate torque levels is the primary requirement. The HC-SFS153's 3,000 rpm rating suits feed rolls and drive rolls running at practical surface speeds without requiring reduction gearing.

Frequently Asked Questions

Q1: Why does the HC-SFS153 (1.5kW) use the MR-J2S-200 (2kW) amplifier rather than the MR-J2S-100?

The amplifier class is determined by the motor's current demand at its operating point, not purely by nameplate wattage. At 3,000 rpm and 1.5kW, the HC-SFS153's current draw exceeds the MR-J2S-100's rated output. Mitsubishi's compatibility documentation confirms MR-J2S-200 for both the HC-SFS153 and HC-SFS203. The practical consequence is useful: once the panel is built around an MR-J2S-200, the motor can be upgraded from HC-SFS153 to HC-SFS203 without any amplifier or panel change — only the motor is replaced and a parameter update confirms the new motor type.

Q2: What is the difference between the HC-SFS153 and the HC-SFS152?

Both are 1.5kW J2-Super motors on a 130 × 130 mm flange with 17-bit encoders and identical mechanical dimensions. The difference is the rated operating point. The HC-SFS152 runs at 2,000 rpm with 7.16 Nm continuous torque. The HC-SFS153 runs at 3,000 rpm with 4.78 Nm continuous torque. Same power, different speed-torque balance. Both use the MR-J2S-200 amplifier. Choose the HC-SFS152 when the axis needs higher sustained torque at moderate speed. Choose the HC-SFS153 when the axis needs higher shaft speed with lighter continuous load torque.

Q3: Can the HC-SFS153 be used with a first-generation MR-J2-200 amplifier?

No. The HC-SFS153 uses the 17-bit J2-Super encoder serial protocol, which the original MR-J2-200 cannot read. Connecting the HC-SFS153 to a first-generation MR-J2-200 amplifier will produce an encoder communication fault on startup. For machines running original MR-J2-200 hardware, the correct motor is the HC-SF153 — same mechanical specification, 14-bit encoder, compatible with both MR-J2-200 and MR-J2S-200 amplifiers.

Q4: Where is the absolute encoder battery and what happens if it is allowed to deplete completely?

The Mitsubishi A6BAT lithium cell is located inside the MR-J2S-200 servo amplifier, not in the motor. It maintains the multi-turn absolute counter through all power-off periods. Replace it at the first low-battery alarm from the amplifier. If the battery fully depletes, the multi-turn counter resets and a reference-return cycle is required on the next startup before the axis can resume production. On machines where homing requires preparation or carries risk, treating the low-battery alarm as an immediate maintenance item rather than a deferred one prevents this from becoming an unplanned production interruption.

Q5: Is the HC-SFS153 still available and what is the current-generation equivalent?

The HC-SFS153 is discontinued by Mitsubishi but remains available through industrial automation surplus dealers and Mitsubishi servo specialist suppliers as new old stock and tested refurbished units. For machines committed to J2-Super hardware, this sourcing path is reliable and well established. For new machine designs or platform upgrades, the current-generation equivalent draws from the HF-KP series or HG-KR series (MR-J4 or MR-JE generation) at equivalent capacity — but note that current-generation 1.5kW low-inertia motors use a smaller physical frame than the HC-SFS153's 130 × 130 mm footprint, so mechanical adaptation is required when transitioning to current hardware.
