Key Features & Benefits
Compact Low-Inertia Design
The HF-KE series features low-inertia rotors that enable rapid acceleration and deceleration, making these motors ideal for positioning applications in assembly machines, pick-and-place systems, and packaging equipment where quick response times improve cycle efficiency.
Keyed Shaft for Positive Torque Transmission
The keyed shaft provides positive rotational engagement between motor and load, eliminating slip and ensuring reliable torque transmission even under demanding duty cycles and frequent direction reversals.
Electromagnetic Brake for Safety
The spring-applied electromagnetic brake holds the axis position when servo power is removed, making this motor suitable for vertical axes, inclined applications, and any load that could drift when de-energized.
Oil Seal Protection
The oil seal at the shaft exit prevents contamination from lubricant mist, coolant, and airborne particles, extending bearing life and motor reliability in industrial environments.
Robust Construction
With Class F insulation (155°C rating), built-in thermal protection, and IP65 ingress protection, this motor is engineered for continuous-duty industrial applications in demanding manufacturing environments.
Compatibility & Installation
The HF-KE23JW1-S100 is designed for use with Mitsubishi MR-J3 series servo amplifiers. The S100 suffix indicates standard cable with connector configuration for direct connection with motor power and encoder cables. For 200W applications, the MR-J3-20A or MR-J3-20B amplifiers are recommended.
Frequently Asked Questions
Does the electromagnetic brake require a separate power supply?
Yes, the electromagnetic brake coil requires a 24V DC power supply from the machine's control circuit, switched by the MR-J3 amplifier's brake interlock output signal.
Is this motor suitable for vertical axis applications?
Yes, the electromagnetic brake makes it appropriate for vertical axes where loads must be held when servo power is removed. The brake engages instantly upon power loss to prevent load dropping.
When is the oil seal necessary?
The oil seal is essential when the motor operates near lubricated mechanisms such as ball screws with centralized lubrication, belt drives with lubricant splash, or any environment with oil mist presence.
What servo amplifier is required?
This motor is compatible with Mitsubishi MR-J3 series amplifiers. For 200W applications, use MR-J3-20A (analogue/pulse command) or MR-J3-20B (SSCNET III network command).
