Embodiment Construction

[0023] In order to make the objectives, technical solutions and effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The following examples are only for explaining the present invention, and do not constitute a limitation of the present invention.

[0024] Figure 1-3 Among them, a stator permanent magnet motor, the stator 1 and the rotor 2 are magnetic cores; the permanent magnets 3 are surface-mounted embedded in the outer surface of the stator teeth, and are placed in sequence along the circumferential direction. Armature windings 4 are wound around the tooth slots of the stator core 1 . The rotor core 2 is surrounded by two sets of mutually independent windings, namely the induction winding 5 and the excitation winding 6, which rotate together with the rotor core. The number of poles of the induction winding 5 is the same as the number of poles of th...

Abstract

Disclosed is a stator permanent magnet type motor. The stator permanent magnet type motor comprises a stator iron core and a rotor iron core which are provided with teeth, wherein grooves are formed in places, adjacent to air gaps, of the stator iron core teeth; permanent magnets are arranged in the grooves and arranged in a circumferential direction in sequence; tooth grooves of the stator iron core are wound with armature windings; and two sets of windings, including induction windings and excitation windings, are arranged on tooth grooves of the rotor iron core. By adoption of the permanent magnet type stator and the dual-winding structure, the stator permanent magnet type motor has high harmonic control capability, and can greatly reduce an electromagnetic force peak value and facilitate reduction of vibration noise of the motor.

Description

technical field [0001] The invention relates to the field of permanent magnet motors, in particular to a stator permanent magnet motor. [0002] technical background [0003] Thanks to the permanent magnet on the stator, the stator permanent magnet motor does not have a magnetic steel protection device, and has the advantage of high robustness of the rotor structure, which has attracted more and more attention this year. However, the current stator permanent magnet motor rotor adopts reluctance rotor, which has many harmonics and it is difficult to reduce harmonics through the design of reluctance rotor, resulting in serious vibration and noise problems, which has become a need to overcome the promotion and application of stator permanent magnet motor. main problem. [0004] Invention content. [0005] In view of the deficiencies of the prior art, the present invention proposes a permanent magnet motor with a stator. Under the condition of ensuring the structural advantage ...
