Abstract

The present invention discloses a stator permanent-magnetic doubly salient disc-type motor, which comprises stator mechanisms, a rotor mechanism and a motor shaft, wherein the rotor mechanism is arranged between the two stator mechanisms, the rotor mechanism and the stator mechanisms are arranged on the motor shaft, each stator mechanism comprises a stator core, two permanent magnets and 2N annular armature windings, 2N stator teeth are evenly distributed on the inner wall of each stator core, a groove between every two adjacent stator teeth is a stator groove, the permanent magnets magnetized in the peripheral direction are arranged in centers of any pair of stator grooves on the same diameter, and the 2N annular armature windings respectively sleeve the 2N stator teeth; and the rotor mechanism comprises a plurality of rotor cores and a non-magnetic-conductive rotor bracket, the plurality of rotor cores are evenly distributed on the outer circumference of the non-magnetic-conductive rotor bracket, and the rotor cores form rotor salient poles. The stator permanent-magnetic doubly salient disc-type motor can effectively improve the reliability of the motor, reduces size and weight of the motor, improves power density and torque density of the motor, and is suitable to be used in occasions with strict requirements on size of generators or motors.

Description

technical field [0001] The invention belongs to the field of motors, in particular to a stator permanent magnet double salient pole disc motor. Background technique [0002] With the development of the new energy industry, wind power, electric vehicles and other fields have become an important part of my country's energy development strategy. Motors are the main equipment for energy conversion. Motors for wind power generation and electric vehicles have become the main research hotspots at this stage. The quality of their electrical and mechanical properties directly affects the efficiency of energy conversion and the cost and reliability of control systems. [0003] Because the disc motor belongs to the axial field motor, it has the characteristics of short axial dimension, compact structure, light weight, small volume, high power density, etc., so it is especially suitable for occasions with special requirements for motor volume such as wind power generation and electric v...
