AC Servo Motor Description
The SMH Series rare earth servo motors feature neodymium-iron-boron
permanent magnet rotors that provide low inertias, small size, high power
density and high peak torques. These compact, environmentally-rugged,
brushless. Low noise and small vibration.
1. An economical, compact design that can function in harsh environments.
2. Neodymium-iron-boron magnet rotors that provide a high torque-to-inertia rating for faster
light machinery acceleration. More than three times load as same as rated torque.
3. A three-phase, sinusoidally wound stator field for smooth operation at slow speeds.
4. .The integrated temperature sensors make usage of working mode in insulation material class
F possible and a high reliability of the motor at the same time.
5. The feedback device encoder(incremental or absolute ) or resolver.
6. IP65 rated(for output shaft is IP54) , quick release connectors for easy installation and maintenance.
7 .The ability to be vertically mounted at any angle with the shaft up or down.
