Apply to valve control and should be operated with special mechanism to be rotated in s specific angle. High power density design is used due to small application space. Special high magnetic conduction material is used.
300V permanent magnet brushless motor and design of sensorless driver integrates switching power and motor driving circuit to control product size and cost effectively.
In order to obtain advantages of quick transient response and smooth operation when drive load directly, back-EMF wave is designed as sine wave. Moving coil is arranged effectively to reduct space occupied.
