Embodiment Construction

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

[0025] Such as figure 2 As shown, the vernier motor of this embodiment includes two stators and a rotor, wherein the stator 1 (in this embodiment figure 2 in the left stator) and stator 3 (in this example the figure 2 middle is the stator on the right).

[0026] The stator 1 and the stator 3 are both ring-shaped structures, and the end face of one end of the stator 1 ring body ( figure 2 The center is the right end face) and there are multiple grooves evenly opened along the axial direction. Similarly, the end face of one end of the stator 3 ring body ( figure 2 A plurality of grooves are evenly opened in the ...

Abstract

The invention discloses an axial-magnetic-field double-stator vernier motor which comprises a rotor and two stators. The rotor is shaped in a circular ring, multiple permanent magnets are uniformly arranged on the circumference of the ring at intervals, the stators are shaped in circular rings, multiple grooves are uniformly arranged on the circumference on the end faces of one ends of the rings and used for containing windings, and stator teeth are formed by protrusions among the grooves. The axial-magnetic-field double-stator vernier motor is characterized in that the two stators are coaxially arranged at an interval in an opposite groove manner, the rotor is coaxially arranged between the two stators, and half of a slot-pitch angle is distant between the stator teeth of the first stator and the stator teeth of the second stator. The vernier motor adopts an axial-magnetic-field double-stator structure, so that the torque density of the vernier motor is similar with that of conventional vernier motors and the power factor is evidently increased up to more than 0.8.

Description

technical field [0001] The invention belongs to the field of motors, and in particular relates to a vernier motor, which is suitable for wind power generation, ship driving and the like. Background technique [0002] As a very important part of renewable energy, wind energy has been highly valued by countries all over the world including China. In the past few years, the installed capacity of wind power has increased by a large proportion for many consecutive years. Especially in China, wind power has become an important renewable energy industry. Among them, the wind turbine is one of the most critical components in the wind power generation system. Its design technology and production process have become the technological commanding heights of the competition among countries all over the world. Especially the direct drive wind turbine has low speed, large volume and heavy weight. , wind turbines with high power density can greatly reduce the weight and cost of wind turbin...
