Description

A switched reluctance motor rotor

technical field

The utility model relates to a motor rotor, in particular to a switched reluctance motor rotor.

Background technique

Traditional permanent magnet synchronous motors usually use a rotor with magnets installed, but the magnets used are susceptible to demagnetization due to temperature, current, etc., which will lead to demagnetization in severe cases, resulting in failure of the permanent magnet synchronous motor. In addition, permanent magnets are expensive, especially rare-earth permanent magnets, which limit their application range for the above reasons. Due to the advantages of simple design, firm structure, no need for magnets, low cost, high efficiency, large starting torque, flexible and simple control, switched reluctance motors have been widely or begun to be used in various fields such as industry, aviation and household use.

At present, the switched reluctance motors on the market still have some defects: the heat dissipation effect of the rotor is not good, it is easy to burn out, and it is not suitable for use in a high temperature environment, and its practicability is not strong.

Utility model content

Aiming at the deficiencies in the prior art, the purpose of the utility model is to provide a switched reluctance motor rotor with simple structure, good heat dissipation effect, not easy to be damaged, good use effect and wide application range.

In order to achieve the above object, the utility model is achieved through the following technical solutions: a switched reluctance motor rotor, including a rotating shaft, a rotor core and salient poles, the rotating shaft is set in the rotor core, and the outer ring of the rotor core is evenly arranged There are a plurality of salient poles, and the rotor core is a heat sink structure, which has a good heat dissipation effect.

Preferably, the surface of the salient pole is provided with heat dissipation grooves.

As a preference, the rotating shaft is sprayed with high-temperature-resistant H-class insulating varnish to ensure that the motor will not age or burn out when running at high temperatures.

Beneficial effects of the utility model: the rotor core is a heat sink structure, coupled with the heat sink on the salient pole and the high temperature resistant paint sprayed on the rotating shaft, so that it can run stably in a high temperature environment, is not easy to be damaged, and has a good use effect ,Wide range of applications.
