Title:
DRIVE CONTROL SYSTEM, MOTOR, AND METHOD FOR CONTROLLING DRIVE CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/150440
Kind Code:
A1
Abstract:
A drive control system, provided with: a motor; a sensor that includes detection magnets provided along the rotation direction on the outer periphery of a rotor of the motor, the detection magnets being configured by alternately disposing a plurality of magnetic poles having a first polarity and a plurality of magnetic poles having a second polarity along the rotation direction of the motor, and also includes a Hall element provided to a stator of the motor at a position facing the outer periphery of the rotor, the Hall element outputting a pulse signal of a first level upon detecting magnetic flux of a magnet having a first polarity and outputting a pulse signal of a second level upon detecting a pulse signal of a second level upon detecting magnetic flux of a magnetic pole having a second polarity; a driver circuit for controlling the operation of the motor; and a control unit for detecting the phase of the motor on the basis of the pulse signal outputted by the Hall element of the sensor, and controlling the driver circuit and driving the motor.
