Abstract

The invention provides a synchronous reluctance motor. The synchronous reluctance motor comprises a stator core (1) and a rotor core (2). The stator core (1) comprises stator teeth (3). The rotor core(2) comprises a plurality of magnetic barrier groups arranged along the circumferential direction, Each magnetic barrier group comprises a plurality of magnetic flux barriers (4) arranged at radial intervals, and a magnetic conductive channel (5) is formed between the adjacent magnetic flux barriers (4) under the same pole, wherein the number of the stator teeth Ns, the number of the magnetic flux barrier layers Bs under each pole and the number of rotor poles 2p have the following relationship: Ns / 2p=Bs+1. According to the synchronous reluctance motor, the torque ripple can be effectively reduced and the motor performance can be improved.

Description

technical field

[0001] The present application relates to the technical field of motors, in particular to a synchronous reluctance motor. Background technique

[0002] Industrial motors are widely used in fans, water pumps, general machinery and other fields. The industry consumes more than 800 billion kWh of electricity and has great potential for energy saving. At present, IE2 asynchronous motors are still the main ones, which have low efficiency, large size, and complex processes; permanent magnet synchronous motors (IPM) can be used in some high-energy-efficiency applications to achieve IE4 or above energy efficiency, but high-performance permanent magnets usually contain rare earth components. It is difficult to save energy and reduce costs.

[0003] With the continuous progress of electromagnetic and control technology, the synchronous reluctance motor without permanent magnet and simple process has become the new darling of the research on de-permanent magnetization ...
