Problems solved by technology

[0007] For this reason, the technical problem to be solved by the present invention is that the structure of the motor in the prior art is unreasonable, and the number of pole pairs of the internal winding and the number of stator permanent magnets need to be consistent and cannot be flexibly adjusted. The number of windings can be inconsistent with the number of winding pole pairs, and it is convenient to wind the stator and rotor double permanent magnet motor

Abstract

The invention discloses a stator and rotor dual-permanent-magnet excitation harmonic motor. A rotor structure of the motor is arranged in a stator structure, and the stator structure comprises magnetism adjustment teeth which are annularly arranged between stator teeth and rotor teeth and an annular magnetic bridge which is arranged between the magnetism adjustment teeth and the stator teeth and is used for connecting the magnetism adjustment teeth with the stator teeth to form a whole; furthermore, a magnetism adjustment slot for mounting a stator permanent magnet is formed between every two adjacent magnetism adjustment teeth; the stator teeth and stator yokes are detachably assembled. The invention provides a novel permanent magnet motor of which a stator and a rotor are provided with permanent magnets; the motor can be improved in the torque/the power density through excitation of the two permanent magnets on the stator and the rotor, so that the motor is extremely high in application potential in a low-speed and high-torque electrical transmission system.

Description

technical field [0001] The invention belongs to the field of motor manufacturing, in particular to a stator-rotor double permanent magnet excitation harmonic motor. Background technique [0002] With the increasingly prominent issues such as energy crisis, global warming, and environmental pollution, human society is facing severe challenges. Production, transportation electrification and utilization of new energy have become our inevitable choice. As the key equipment of electromechanical energy conversion, the overall performance of the motor directly affects the energy utilization efficiency. With the development of power switching devices and permanent magnet materials, permanent magnet motor technology has been widely used in electric vehicles, industrial transmission, wind power generation and other fields. Compared with the traditional electric excitation motor, the rare earth permanent magnet motor with iron neodymium boron as the main material has the advantages o...
