Abstract

The invention relates to the field of motors, in particular to a brushless direct-current motor special for an electric vehicle. The brushless direct-current motor comprises a motor, an output shaft and a protective shell, and is characterized in that the protective shell comprises a chassis, a left half column plate, a right half column plate and a top plate, a flanging ring is fixed to the edgeof the top end of the chassis, and through screw holes are evenly formed in the center circumference of the side face of the flanging ring; half grooves are formed in the bottom ends of the outer sidefaces of the left half column plate and the right half column plate, connecting screw holes are evenly formed in the circumferences of the centers in the half grooves, matching grooves are formed inthe inner side faces of the left half column plate and the right half column plate, sliding grooves are formed in the centers of the side faces of the matching grooves, and sliding blocks are slidablyconnected into the sliding grooves. Inserting grooves are formed in the two ends of the left half column plate at equal intervals, limiting holes are formed in the centers in the inserting grooves, mounting screw holes are formed in the top ends of the left half column plate and the right half column plate, inserting blocks are arranged at the two ends of the right half column plate, through holes are formed in the centers of the inserting blocks, a connecting bearing penetrates through the center of the top end of a top disc, and an inserting ring groove and a threaded through hole are formed in the bottom end and the top end of the top disc.

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...
