Brushless wheel hub motor used for new energy automobile

Abstract

The invention discloses a brushless wheel hub motor used for a new energy automobile. A left ultrathin bearing, a right ultrathin bearing, an O-shaped outer rotor and an O-shaped inner stator form anultrathin O-shaped brushless motor, the ultrathin O-shaped brushless motor is mounted inside the inner circle of a wheel rim to form a wheel rim motor, the original braking mechanism inside the wheelrim does not change, the O-shaped outer rotor comprises a rotor body and a permanent magnet group, an annular groove is formed in the rotor body, the left ultrathin bearing is mounted on the inner circle of the left end of a magnetic conductive ring in a close fit manner, the right ultrathin bearing is mounted on the inner circle of the right end of the magnetic conductive ring in a loose fit manner, the O-shaped inner stator is arranged on the inner circle of the left ultrathin bearing and the inner circle of the right ultrathin bearing, and the O-shaped inner stator comprises a stator body,an electromagnetic coil winding iron core group and a motor shaft. The brushless wheel hub motor is simple in structure, stable and reliable, the volume, weight and cost of the wheel rim motor are reduced further, and the brushless wheel hub motor is of significance for upgrading, modification and transformation of commonly used fuel oil automobiles.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a brushless hub motor for new energy vehicles. Background technique [0002] At present, the drive motor of new energy vehicles is widely used as a motor drive device integrated with the engine. With the rapid development of new energy vehicles, the drive motor is also improving. In order to meet the development requirements of new energy vehicles, various Although the motor drive devices arranged on the wheel have different advantages, their disadvantages are that they are all wheel motors independent of the wheels, and they must be equipped with a reducer to meet the requirements, which makes the structure of the whole machine complex and costly. Addition, some electric vehicles use a brushless and toothless large hub motor, the disadvantage is that the motor is bulky and cannot be installed with reliable braking components.
