Product Description
Mitsubishi HC-SF102 AC Servo Motor
A 1 kW motor that has earned its reputation through decades of reliable performance in CNC machines across various industrial applications.
Product Overview
The Mitsubishi HC-SF102 is a 1.0 kW (1,000W) AC brushless servo motor from the HC-SF series, designed for medium-inertia applications. Operating at 2,000 RPM with rated torque of approximately 4.78 Nm, this motor features a three-phase AC supply at 123V and 6A rated current.
Key Features
- Smooth straight cylindrical shaft at φ24 mm
- 110 mm centering diameter with 130 * 130 mm flange
- Natural convection cooling (unventilated)
- External OSA17-20 encoder system (sold separately)
- Compatible with MR-J2 series servo amplifiers

External Encoder Architecture
The HC-SF102 utilizes a rear auxiliary shaft designed to accept the OSA17-20 encoder unit as a separate, field-fitted component. This modular design allows for independent replacement of either the motor or encoder, minimizing downtime during maintenance.
Typical Applications
Well-suited for various industrial applications including:
- X, Y, and Z feed axes on vertical machining centers
- Horizontal machining center feed axes
- Rotary table drives
- Automated material handling systems
Drive Compatibility
The HC-SF102 is specifically designed for MR-J2 series servo amplifiers. The OSA17-20 encoder communicates using analog encoder signal architecture and is not compatible with newer MR-J2S, MR-J3, or MR-J4 amplifiers that use digital serial encoder protocols.
Frequently Asked Questions
Does the HC-SF102 come with the OSA17-20 encoder?
Not as a standard inclusion - the encoder is a separate component. Always confirm whether the OSA17-20 measuring system is included or needs to be sourced independently when ordering a replacement.
What is the difference between the HC-SF102 and the HC-SFS102?
Both are 1 kW, 2,000 RPM motors, but they belong to different drive generations. The HC-SF102 uses an external OSA17-20 analog encoder for MR-J2 amplifiers, while the HC-SFS102 has a built-in 17-bit absolute encoder for MR-J2S amplifiers.
Is there a keyed shaft version of the HC-SF102?
Yes. The HC-SF102K features the same motor configuration with the addition of a keyway on the output shaft for positive mechanical interlock with torque transmission.
Can the HC-SF102 be used on a vertical axis?
Without a brake, the motor cannot hold axis position when de-energized. For vertical axes, the HC-SF102B (brake-equipped variant) is the correct choice.
What are the most common service issues with the HC-SF102?
Bearing failure at both ends and external OSA17-20 encoder issues are the most frequently reported mechanical and electrical faults. Power connector damage is also common on motors from active service.
The Mitsubishi HC-SF102 is a legacy servo motor. Confirm encoder availability, drive compatibility, and shaft configuration against your machine's original specifications before ordering.
