Novel permanent magnet synchronous motor

Abstract

A novel permanent magnet synchronous motor disclosed by the present invention comprises a motor, the motor comprises a permanent magnet and a coil, the coil is arranged in the permanent magnet, the coil is marked with a coil serial number, the permanent magnet is marked with a pole direction of a magnetic field, and the inner wall of the permanent magnet is provided with a sensor. The sensor is used for judging the sequence number of the coil and transmitting a signal to the controller, the controller distributes magnetic field distribution of the coil according to the sequence number of the coil, that is, when the rotor rotates by one coil, the magnetic field of the coil is switched immediately, when the stator is a permanent magnet, the sensor is located on the permanent magnet, and the winding methods of the opposite coils are opposite, that is, when current is conducted, the magnetic field pole directions are opposite. The whole coil of the motor works simultaneously, the magnetic field and electric energy utilization efficiency is high, the starting current is small, and control and manufacturing are easy.

Description

technical field [0001] The invention belongs to the technical field of motors, in particular to a novel permanent magnet synchronous motor. Background technique [0002] At present, the best performance of the permanent magnet synchronous motor is the Tesla motor, that is, IPMSynRM, which combines the permanent magnet motor with the synchronous motor, and uses six sets of V-shaped permanent magnets to improve the performance of the motor, but the magnetic induction line of the permanent magnet moving at high speed It will cut the stator coil to generate counter electromotive force, and the utilization efficiency of the magnetic field and electric energy is not high, the starting current is large, and the starting torque needs to be improved. Contents of the invention [0003] In order to solve the above problems, the invention provides a novel permanent magnet synchronous motor, the specific scheme is as follows: [0004] A new type of permanent magnet synchronous motor, ...
