Abstract
The utility model relates to an electric wheel with a built-in brushless DC motor, which can effectively improve system efficiency. The utility model comprises the following technical proposal that an electric wheel with the built-in brushless DC motor is characterized in that: the utility model is provided with a motor shaft; a stator of the brushless DC motor is pressed on the motor shaft; a rotor shell is arranged outside the stator; rotor magnetic steel of the brushless DC motor is fixed inside the rotor shell; a wheel rim is fixed outside the rotor shell; two motor end covers are arranged on the motor shaft as well; a motor bearing is arranged between the motor end covers and the motor shaft; two motor end covers are fixed with the rotor shell. The utility model integrates the functions of the motor, transmission, the wheel, etc., which are changed into an integral module. A shell of the motor is just a wheel hub of the wheel, so as to directly transform electric energy into mechanical energy. The cancel of a transmission link and the application of the high-efficiency brushless DC motor greatly improve the efficiency of the whole system.
Description
Technical field
The utility model relates to a kind of electric wheel, especially a kind of electric wheel of built-in brshless DC motor.
Background technology
Traditional electric motor car is by electric power (cable, storage battery etc.) drive motor, through a cover drive system power is passed to wheel then, thereby drives body movement.Such structure drive path is long, and the whole drive system of complex structure takes up room greatly, because link is many, and low, the poor reliability of system effectiveness.
Summary of the invention
The purpose of this utility model provides a kind of electric wheel of built-in brshless DC motor, makes system effectiveness be able to effective raising.
Realize the technical scheme of the utility model purpose:
A kind of electric wheel of built-in brshless DC motor is characterized in that:
Have motor shaft, be press-fitted the stator of brshless DC motor on the motor shaft;
The arranged outside of stator has rotor case, and the rotor case inboard is fixed with the rotor magnetic steel of brshless DC motor, and the outside of rotor case is fixed with rim of vehicle wheel;
Two electric motor end caps also are housed on motor shaft, are provided with motor bearings between electric motor end cap and the motor shaft, two end cap and aforesaid rotor case are fixed.
The beneficial effect that the utlity model has:
The function of motor, transmission and wheel etc. that the utility model is integrated has become them into the module of an one.The shell of motor is exactly the wheel hub of wheel, directly electric energy is converted into mechanical energy.The cancellation of transmission link and the application of dc brushless motor efficiently make overall system efficiency improve greatly.The structure of electric vehicle system has not only greatly been simplified in such design, has shortened drive path, and improved system rigidity, reliability and can be handling.
