Problems solved by technology

The disadvantage is that the peak area of ​​the motor efficiency is small, and a large current is required when carrying a large torque, which is easy to damage the battery and permanent magnet
The structure diagram of the existing permanent magnet vernier motor is shown in Figure 1, its disadvantages are: the excitation magnetic field cannot be changed in a specific operating environment, and it is easy to cause problems such as loss of excitation

Embodiment Construction

[0024] In order to make the technical solution of the present invention clearer, the present invention will be further described below in conjunction with specific examples. The following examples are only used to explain the present invention in detail, and do not constitute a limitation to the present invention.

[0025] Such as figure 2 , 3 As shown, the stator electric excitation vernier motor of this embodiment includes two stators and a rotor, that is, an outer stator, an inner stator and a rotor. An annular rotor 2 and an annular inner stator 5, wherein gaps are provided between the outer stator 1 and the rotor 2, and between the rotor 2 and the inner stator 5 to form air gaps. On the inner wall of the outer stator 1, a plurality of grooves are evenly spaced in the circumferential direction, and armature windings 3 and field windings 4 are embedded in each groove, and the protruding parts between the grooves form outer stator teeth; A plurality of grooves are evenly ...

Abstract

The invention discloses a stator electro-magnetic vernier motor. The stator electro-magnetic vernier motor is characterized in that the stator electro-magnetic vernier motor comprises a stator, wherein the stator is in a circular ring shape, a plurality of grooves are formed in the circumferential direction the wall of the ring body, an armature winding or an excitation winding is embedded in each groove, and projection parts among the grooves form stator teeth; a rotor, wherein the rotor is in a circular ring shape, a plurality of magnetic regulating blocks made of a magnetic conductive material are uniformly arranged in the circumferential direction of the ring body at intervals, the stator and the rotor are coaxially assembled in a sleeving manner, and an interval exists between the stator and the rotor. According to the invention, the armature windings and the excitation windings are embedded in the stator grooves, and the rotor magnetic regulating blocks are utilized, so that low-speed large torque is not provided by a vernier effect of a permanent magnet, the magnetic loss problem of a permanent magnet vernier motor in a specific operation environment is solved, the efficiency is improved, and the cost is saved.

Description

technical field [0001] The invention belongs to the field of motors, and in particular relates to a stator electric excitation vernier motor, which is suitable for low-speed, high-torque application fields, such as wind power generation, driving of automobiles or ships, and the like. Background technique [0002] In recent years, with the rise of electric vehicles, in-wheel motors have aroused people's attention again. The electric transmission system is directly driven by the hub motor, which can reduce the complexity of the mechanical structure of the vehicle drive system, improve the efficiency and reliability of the system, and reduce the manufacturing cost. The specific advantages are: (1) The power control is changed from a hard connection to a soft connection, realizing the stepless speed change of each electric wheel and the differential speed requirements between each electric wheel, omitting the traditional mechanical control shift device, clutch, transmission , t...
