Working Principle The motor uses electronic commutation where a three-phase inverter servo drive energizes the stator windings in sequence based on rotor position feedback from the incremental encoder. The interaction between the stator’s rotating magnetic field and the permanent magnets on the rotor produces continuous torque. The encoder provides position and velocity feedback for closed-loop servo control, enabling precise motion profiles and disturbance rejection.
Installation Requirements
- Mount with flexible coupling allowing misalignment tolerance less than 0.1 millimeters angular and 0.05 millimeters parallel
- Do not exceed 5000 RPM under any operating condition
- Ensure connector is sealed when operating in washdown environments
- Use shielded motor cable with maximum 15 meter length without additional drive-side filtering
Operating Precautions
- Verify drive voltage and current compatibility with motor ratings
- Monitor bearing temperature during sustained high-speed operation
- Maintain IP65 seal integrity by ensuring connector covers are properly seated
- Avoid mechanical shock to shaft during installation
