Description
Technical Field
The utility model relates to a switched reluctance motor.
Background
The switched reluctance motor drives the rotor to move by adopting different magnetic lines of force between the stator and the rotor at each moment. The stator and the rotor generally meet the salient pole type tooth space structure, the rotor has no winding coil and is not a permanent magnet, and the stator is provided with an annular winding coil. However, because the stator and the rotor of the switched reluctance motor are of a double salient pole structure, the noise and vibration of the motor are serious in the operation engineering. Compared with the traditional switched reluctance motor, the novel switched reluctance motor can effectively reduce vibration in the operation process and reduce noise, and the output power is not influenced, so that the motor development can be greatly promoted. Therefore, the motor structure capable of reducing noise and vibration is significant.
Disclosure of Invention
For solving the great technical problem of switched reluctance motor vibration and noise, the utility model provides a switched reluctance motor.
The utility model relates to a switched reluctance motor's technical scheme is:
a switched reluctance motor includes a stator, a rotor, and a winding coil. The method is characterized in that: the stator and the rotor are matched by adopting a salient pole type tooth socket, a ring-shaped winding coil is wound on a stator salient pole, and a salient pole at the tail end of the rotor is in a step shape.
In the scheme, the stator teeth are composed of a certain number of teeth and grooves, and the number of the teeth and the number of the grooves are 14 and 13 respectively.
In the above scheme, the teeth and grooves on the stator teeth are symmetrically distributed along the stator center line, wherein the largest groove is located at the center of the stator end.
In the scheme, the through hole is formed in the protruding electrode at the tail end of the rotor.
By adopting the scheme, the noise and the vibration of the motor can be effectively reduced when the motor works and operates. Switched reluctance motors operate according to the "reluctance minimum principle". By changing the path of the magnetic induction line, the radial magnetic flux can be effectively reduced, the radial force is reduced, the tangential force is increased, the torque pulsation generated in the operation process can be effectively reduced, and the generated noise is reduced.
