Function & Application
This motor is designed for:
- High-load, stable motion systems (high inertia type)
- CNC machines (heavy axis)
- Industrial robotics
- Conveyor & indexing systems
- Packaging machines
Compared to MSMF (low inertia), this MHMF motor handles heavier loads more smoothly but responds slightly slower.
Simple Understanding
MHMF082L1U2M = 750W high-inertia servo motor
- Same speed (3000 rpm) and torque (2.39 Nm)
- But better for heavy mechanical loads
- No brake (add external or choose V2M if needed)

Core Function
Converts electrical commands from a servo driver into controlled rotary motion with continuous feedback correction.
What it does in practice
1. Position Control
- Moves to exact positions (angles or linear distance via screw/belt)
- Holds position accurately using encoder feedback
- Used in CNC axes, indexing tables, robotics
2. Speed Control
- Maintains commanded speed (e.g., 3000 rpm)
- Automatically adjusts torque if load changes
- Ensures smooth, vibration-free rotation
3. Torque Control
- Provides 2.39 Nm continuously
- Delivers high peak torque (~8.36 Nm) for acceleration or load changes
4. Closed-Loop Feedback System
- Built-in 23-bit encoder monitors position continuously
- Driver corrects any error instantly
- Result: very high precision and stability
Special Function (High Inertia Type)
This MHMF model is designed for:
- Heavy loads
- Stable rotation (less vibration)
- Better performance with large mechanical systems
Compared to low-inertia motors:
- Slower response
- But smoother and more stable under load
Typical Applications
- CNC machines (heavy axis)
- Industrial robots
- Conveyor systems
- Packaging machinery
- Rotary indexing tables
Important Note
- This U2M version has NO brake
- It cannot hold position when power is OFF
- For vertical loads, brake version (V2M) is required
