Working Principle The servo drive outputs three-phase variable frequency AC current to motor stator winding. Rotating magnetic field drives permanent magnet rotor to rotate. The integrated absolute encoder continuously feeds back rotor position and speed signal to servo drive. Drive adjusts current and frequency in real time according to position command to realize precise speed, torque and closed-loop positioning control.
Installation Requirements
- Mount motor flange on rigid mechanical bracket
- Align coupling concentricity during mechanical assembly
- Use shielded servo power cable and shielded encoder cable
- Keep ambient temperature within -20 °C to +40 °C
- Ensure proper heat dissipation space around motor housing
- Perform motor parameter auto-tuning after wiring completion
- Reliable protective earth connection
Precautions
- Do not apply mechanical impact to motor shaft and encoder end
- Avoid overload torque exceeding peak torque rating continuously
- Cable shielding must be single point grounded
- Prevent metal dust and liquid ingress into motor housing
- Do not disassemble encoder module
- Check bearing temperature during long time continuous operation
