A new energy vehicle motor with speed limiting function and good cooling effect

Abstract

The invention relates to a new energy automobile motor having a speed limit function and a great heat radiation effect. The new energy automobile motor comprises a body, a PLC, a rotor winding, a transmission shaft, a supporting block, a connecting shaft and at least two stator windings. The PLC is arranged in the body. One side of the body is arranged on the transmission shaft in a sleeving way.The transmission shaft is horizontally arranged. The rotor winding and the supporting block are arranged on the transmission shaft in a sleeving way. The rotor winding is arranged in the body. The stator windings are circumferentially and evenly distributed at the periphery of the rotor winding. The stator windings and the supporting block are fixed on the internal wall of the body. One side, which is away from the transmission shaft, of the body is arranged on the connecting shaft in a sleeving way. The body is internally provided with a heat radiation mechanism and a speed limit mechanism. One side, which is away from the connecting shaft, of the body is provided with a cooling mechanism. According to the new energy automobile motor having the speed limit function and the great heat radiation effect, the situation of excessively high rotating speed of the motor can be avoided through the speed limit mechanism and the heat radiation effect of the motor can also be enhanced through theheat radiation mechanism.

Problems solved by technology

[0003] Existing new energy vehicle motors will experience overheating when they run for a long time. Overheating is very detrimental to the insulation of the motor. The most sensitive part of the motor to heat is the insulation of the stator winding. Each insulation material can only withstand a certain temperature. If the temperature exceeds the allowable temperature, the aging of the insulation will be accelerated, the service life of the motor will be shortened, and various accidents may be caused due to insulation damage. Excessive speed causes new energy vehicles to overspeed, which seriously affects driving safety
