Mitsubishi Electric HF-SP352 AC Servo Motor
A medium-inertia, medium-capacity 200 V servo motor rated 3.5 kW at 2000 r/min.
Technical Summary
HF-SP352 is a standard HF-SP servo motor for industrial motion axes that require medium inertia and medium capacity. The motor was designed around the matching Mitsubishi servo-amplifier and encoder architecture.
The model is discontinued, so replacement planning should cover mechanical dimensions, connectors, feedback compatibility and amplifier support rather than relying on power alone.

Features
- Combines medium-inertia rotor characteristics with a 3.5 kW output class for stable machine motion.
- Uses the 18-bit encoder architecture specified for the HF-SP execution.
- Supports operation to the documented 3000 r/min maximum speed when applied within the approved system.
- Provides a standard motor configuration for integration with the matching 200 V MELSERVO platform.
Compatibility
- Match the servo amplifier, encoder cable, motor power cable and connector execution.
- Check shaft, flange, brake requirement, mounting orientation and machine inertia before substitution.
- A migration to HG-SR352 requires review of dimensions, connectors, cables and amplifier compatibility.
Replacement
- Back up amplifier parameters and record motor, feedback, brake and mechanical-coupling details.
- Inspect the driven mechanism for overload or alignment faults before installing another motor.
- Complete encoder, brake, direction, tuning and controlled-load tests before production release.
FAQ
Is HF-SP352 still in current production?
No. Production was discontinued in May 2019, and the published repair-support deadline is May 2026.
Is HG-SR352 a drop-in replacement for HF-SP352?
It is a migration example, not an automatic drop-in substitute; mechanical dimensions, connectors, cables and amplifier architecture must be reviewed.
What amplifier information is needed with an HF-SP352 enquiry?
Provide the amplifier model, parameter backup, encoder and power cable numbers, connector photographs and machine supply details.
Can any 3.5 kW servo motor replace HF-SP352?
No. Rated speed, inertia, feedback, mounting, shaft, connectors, amplifier compatibility and machine tuning all matter.
What should be tested after installing HF-SP352?
Verify encoder recognition, brake behavior if fitted, motor direction, tuning, limits and controlled operation under the actual load.
What machine data helps plan an HF-SP352 migration?
Record flange and shaft dimensions, coupling, load inertia, speed and torque duty, cable routes, amplifier model and control-system constraints.
