Abstract

The invention discloses a permanent magnet motor capable of effectively recovering electric energy. Components of the permanent magnet motor comprise a motor shaft and a motor housing which is coaxially arranged with the motor shaft. A rotor core is fixedly installed on the motor shaft, and a plurality of permanent magnets are evenly distributed on the circumference of the outer diameter of the rotor core. A plurality of winding modules which are circumferentially and uniformly distributed and correspond to the plurality of permanent magnets are arranged on the inner diameter of the motor housing; the winding module comprises a spliced stator core; the stator core is provided with a conductor groove processed along the direction of the magnetic line of force of the permanent magnet; a copper conductor is installed in the conductor groove; and an insulation isolation layer is arranged between the conductor groove and the copper conductor. The permanent magnet motor has the advantages that the electric energy recovery efficiency of the permanent magnet motor is enhanced, energy is saved, the operation stability of the motor and the overall efficiency of the motor are improved, the service life of the motor is prolonged, and the overall performance of a product taking the permanent magnet motor as a driving motor is improved.

Description

technical field [0001] The present invention relates to the technical field of motors, and more specifically, the present invention relates to a permanent magnet motor capable of effectively recovering electric energy in the technical field of motors. Background technique [0002] The development and development of electromagnetic products, especially the application of permanent magnet materials in permanent magnet motors, has opened up a very broad space for the development and promotion of permanent magnet motors. Because permanent magnet synchronous motors have small size, simple structure, high Reliability, high control accuracy, high torque density, good torque stability and low noise, so it is used in various fields such as robots, aerospace, radar antennas, precision electronic equipment, agricultural machinery equipment, CNC machine tools, electric vehicles, etc. Has been widely used. [0003] Those skilled in the art know that permanent magnet motors often need to...
