Material Composition
Stator with high-grade silicon steel laminations. Rotor with high-energy neodymium magnets. Shaft made from high-strength steel. Housing is aluminum alloy for heat dissipation.
Structural Characteristics
Compact, flange-mounted design. Integrated holding brake for vertical axis safety. Rear-mounted encoder with protective cover. Shaft seal to prevent ingress of contaminants.
Working Principle
Operates as a permanent magnet synchronous motor. The drive controller supplies three-phase AC current to the stator windings, creating a rotating magnetic field that interacts with the rotor magnets to produce precise rotational motion.
Installation Requirements
Mount securely to the machine structure using the specified mounting holes. Ensure proper alignment with the driven load to prevent bearing wear. Connect the motor and encoder cables using shielded connectors.
Usage Precautions
- Do not exceed the permissible radial and axial loads on the shaft.
- Ensure the motor is properly grounded.
- Avoid exposing the motor to excessive shock or vibration.
- Allow the motor to cool down before performing maintenance.
