The invention provides a novel ultralow-speed large-torque switch reluctance motor. The superlarge-torque switch reluctance motor comprises a stator assembly and a rotor assembly which are matched with each other, wherein the stator assembly comprises a stator machine shell, stator salient poles and a stator winding, the stator salient poles are arranged on the inner wall of the stator machine shell, the stator salient poles surround the circumference of the stator machine shell, and the stator winding is wound on a stator iron core; the rotor assembly comprises a rotor shaft, rotor salient poles and an exciting winding, the rotor salient poles surround the circumference of the rotor shaft, the arc surfaces of the stator salient poles are opposite to the arc surfaces of the rotor salient poles, the stator salient poles and the rotor salient s are at least partly staggered in a concave-convex mode to form a teeth shape, the arc length of the arc surfaces of the stator salient poles is larger than the arc length of the arc surfaces of the rotor salient poles so that the length of a closed magnetic circuit formed between adjacent stator salient poles and the corresponding rotor salient poles can be shortened, and the exciting winding is arranged on the rotor salient pole. By means of the motor, the short magnetic circuit can be formed, and the aims of improving the torque and reducing the rotating speed are achieved.
Description
technical field [0001] The invention belongs to the technical field of motors, in particular to a novel ultra-low-speed and high-torque switched reluctance motor. Background technique [0002] In recent years, with the breakthrough of permanent magnet materials and the development of the motor industry, the existing low-speed high-torque permanent magnet motors mostly use frequency conversion to start. Power frequency self-starting. When the rated parameters are required to be certain, that is, the speed and power are constant, the number of pole pairs of the motor must be increased to realize self-starting at a power frequency of 50 Hz. However, the high-power asynchronous starting permanent magnet synchronous motor has a large volume and a large moment of inertia. In addition, the permanent magnet braking torque at the starting stage is very large after the number of pole pairs increases. Even if the rotor starting winding is connected in series with the starting resistor...
