Title:
MOTOR
Document Type and Number:
WIPO Patent Application WO/2010/124592
Kind Code:
A1
Abstract:
A motor comprises a motor body (501), a controller and an electromagnetic sensor. The electromagnetic sensor is used for sensing rotation of a motor shaft, and outputs sensed information representing the position of the motor shaft to the controller. Accurate control of the motor is realized by the controller. The number of magnet poles involved in the electromagnetic sensor is independent of the number of rotor poles of the motor. Thus the match between the motor and the electromagnetic sensor is flexiable, control accuracy, response speed of the system and reliability are improved, and production cost is reduced.
