Abstract

The invention discloses a disc-type motor, and the motor comprises a stator, a rotor, a position sensor and a control circuit. The stator comprises winding units, and the winding units are arranged between the stator and the rotor, wherein the number of the winding units is 3N, every three adjacent winding units form a three-phase winding, and N is a natural number greater than or equal to 1; theposition sensor is opposite to the rotor, and the position sensor is used for detecting the rotating speed and the suspension height of the rotor; the control circuit is electrically connected with the winding units and the position sensor, and the control circuit is used for receiving a detection result of the position sensor and controlling the rotating speed and the suspension height of the rotor through the winding units. According to the scheme, the operating state of the rotor is monitored in real time through the position sensor, so the operating state of the rotor is adjusted in time by the control circuit, and the problems of low operating stability and low accuracy of the conventional disc type motor are solved.

Description

Technical field [0001] The invention relates to a motor, in particular to a disc motor. Background technique [0002] Motors are widely used in manufacturing, medical equipment, robotics and other industries. With the development of technology, more and more fields require motors to meet the requirements of miniaturization, integration (integration of mechanical parts and control parts), and flexible control. [0003] Disc motor is a very important form of motor structure. The motor stator and rotor are arranged in the axial direction and made into a disc shape. This type of motor has the following defects: [0004] 1. At present, the mechanical part and control part of many motors are separated independently, the size is large, and the space utilization is insufficient; [0005] 2. The rotor of the motor is driven by the rotating shaft and has mechanical bearings, which generates mechanical friction, heat and wear; [0006] 3. At present, most motors can only realize the rotation of t...
