Mitsubishi HC-SFS53 AC Servo Motor — New In Box, Factory Sealed

Condition: Brand New · Original Packaging · Factory Sealed

Part Number: HC-SFS53 / HCSFS53

Series: HC-SFS | Compatible Amplifiers: MR-J2S / MR-J3 / MR-J4

Overview

Compact footprint. 3,000 rpm. Ready to work.

The Mitsubishi HC-SFS53 is a 500W AC servo motor rated for 3,000 rpm continuous operation — the higher-speed variant in the HC-SFS 500W range, designed for applications where cycle time and axis response matter as much as torque. Delivering 1.59 N·m continuous with a peak of 4.78 N·m, it handles light-to-medium axis loads with the precision and repeatability the HC-SFS series is known for.

Small machine, tight cabinet, fast cycle — that's the environment this motor was built for.

Every unit ships sealed in its original Mitsubishi factory carton. Uninstalled. Unpowered. No rework, no repackaging, no field history of any kind.

Key Specifications

Built for Speed, Backed by Precision

At 3,000 rpm, the HC-SFS53 sits at the upper end of the HC-SFS 500W range. That speed headroom translates directly into faster axis traversal, shorter non-cutting time in machining applications, and more responsive positioning in high-cycle automation — without stepping up to a heavier, larger motor frame.

The 17-bit absolute encoder manages the precision side. With 131,072 pulses per revolution and true absolute position retention across power cycles, the controller always knows where the axis is. No homing sequence on startup. No position loss after an e-stop. In facilities running multiple shifts or experiencing frequent power interruptions, that's a real operational advantage.

IP65 shaft sealing keeps the motor serviceable in environments where coolant mist, fine metal dust, or airborne particulates are part of daily reality. Class F insulation adds thermal headroom for continuous-duty cycles running long without forced cooling.

Typical Applications

Small CNC Lathes & Machining Centers — Feed axes and turret drives where a compact 500W motor at 3,000 rpm provides the speed-torque profile needed for light cutting and fast rapid traverse.

Semiconductor & Electronics Assembly Equipment — Pick-and-place, bonding, and inspection machines that require precise, repeatable positioning in a small motor package.

Laser Cutting & Marking Systems — High-speed positioning axes where fast response and encoder accuracy directly affect cut quality and throughput.

Automated Test Equipment — Motion axes in functional testers and measurement systems that need clean, repeatable positioning without mechanical play.

General Factory Automation — Indexing tables, rotary positioners, and conveyor drives in cells where floor space is limited and cycle time drives output.

A Note on Availability

The HC-SFS53 sees wide deployment across compact machine platforms from multiple OEMs. When one fails unexpectedly, lead times from distribution can stretch — particularly for models outside the most common power ratings. A sealed, verified-new spare on hand eliminates that exposure entirely. For system integrators building to customer deadlines, stocking a unit before the project starts removes one schedule risk before it can become a problem.

Frequently Asked Questions

Q1: What is the difference between the HC-SFS52 and the HC-SFS53?

A: Both are 500W motors in the HC-SFS series. The HC-SFS52 is rated at 2,000 rpm with a higher continuous torque of 2.39 N·m. The HC-SFS53 runs at 3,000 rpm with a rated torque of 1.59 N·m. Choose based on whether the application needs more torque at lower speed or faster axis traversal at higher speed.

Q2: Which servo amplifiers are compatible with the HC-SFS53?

A: The HC-SFS53 is compatible with Mitsubishi MR-J2S, MR-J3, and MR-J4 series servo amplifiers. Verify that the amplifier's rated current output matches the motor's 500W / 200V specification before commissioning.

Q3: Does this motor include a built-in holding brake?

A: No. The HC-SFS53 is the standard variant without an electromagnetic brake. For vertical axis or gravity-loaded applications that require mechanical position holding on power loss, specify the HC-SFS53B instead.

Q4: What does "New In Box, Factory Sealed" mean for this listing?

A: The motor has never been installed, powered on, or field-tested. It remains in its original Mitsubishi packaging with all factory seals intact — the same condition it left the production facility in. No refurbishment or relabeling has taken place.

Q5: Does the 17-bit encoder require a battery to retain absolute position?

A: Single-turn absolute operation requires no battery. For multi-turn absolute position retention across power cycles, a battery backup is needed on the amplifier side — this is an amplifier-level requirement, not a limitation of the HC-SFS53 motor itself.
