There is a flanging ring, the center circumference of the side of the flange ring is evenly provided with through screw holes, the bottom of the outer side of the left half column plate and the right half column plate is provided with a half groove, and the inner center circumference of the half groove is uniformly provided with connecting screw holes, the left half column plate An anastomotic groove is provided on the inner side of the column plate and the right half column plate, and a chute is arranged in the center of the side of the anastomotic groove, and a slider is slidably connected to the inside of the chute, and an extension plate is fixed on the side of the slider, and two ends of the left half column plate are equally spaced. Slot, limited hole is set in the center of the slot, mounting screw holes are set on the top of the left half column plate and the right half column plate, insert blocks are set at both ends of the right half column plate, a through hole is opened in the center of the insert block, and the top of the top plate A connecting bearing runs through the center, an insert ring groove is provided at the bottom of the top plate, and a threaded hole is provided at the top of the top plate.

Description

technical field [0001] The invention relates to the field of electric motors, in particular to a special brushless direct current motor for electric vehicles. Background technique [0002] The brushless DC motor consists of a motor body and a driver, and is a typical mechatronic product. The stator windings of the motor are mostly made into a three-phase symmetrical star connection, which is very similar to the three-phase asynchronous motor. With the development of modern brushless DC motor technology, the requirements for high protection and ease of use of brushless DC motors for electric vehicles continue to increase. It is necessary to improve the convenience of installation, reduce the cost of use, and have high efficiency and The requirement of high life is also increasing. The development of brushless DC motors for electric vehicles must meet the requirements of the development of modern brushless DC motor technology. The existing brushless DC motors for electric veh...
