Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings.

[0028] Such as figure 2 As shown, a motor with a built-in control system includes a shield 21, a casing 25, a rotor 26, a stator 27 and a main shaft 28; it is characterized in that it includes a motor control system; the structure of the motor body breaks through the design structure of a conventional motor, From one side of the motor to the other side are the shield 21, the control system 22, the rear end cover 24, and the casing 25; the casing includes a rotor 26, a stator 27, and a main shaft 28; The rear end cover 24 of the motor is not only a component of the electrode, but also a fixed part of the control system. For the motor, the rear end cover 24 and the front end cover 29 are jointly used to support the bearing 28; The role of heat dissipation.

[0029] Such as image 3 As shown, the motor control system 22 is installed outside the rear end cover 24 of th...

Abstract

The invention discloses a motor with a built-in control system. The motor comprises a protective cover, a shell, a rotor, a stator and a main shaft. The motor is characterized in that the motor comprises a motor control system; the protective cover, the control system, a rear end cover and the shell are sequentially arranged from one side of the motor to the other side of the motor; the rotor, the stator and the main shaft are arranged in the shell; a front end cover is installed at the outmost side of the motor; the motor control system is installed at the outer side of the rear end cover of the motor; and the motor control system includes a control board, a power driving board and a Hall adjustment mechanism. The motor and the control system can be integrated. According to the motor with the built-in control system provided by the invention, factors such as the cost, failure rate and efficiency of an electric vehicle power system are fully considered, and the mechanical structure and the control system can be integrated. Compared with an existing split type motor control device, the cost of the motor provided by the invention can be reduced by more than 20%, and the failure rate of the motor can be significantly reduced.

Description

technical field [0001] The invention relates to a motor control device, in particular to a motor with a built-in control system. Background technique [0002] Petroleum shortage and air pollution are two major problems plaguing the automobile industry. All countries in the world have invested a lot of money in the research and development of clean energy vehicles. I have seen that the research and development of electric vehicles is in the stage of demonstration operation and industrial production recommendation. [0003] The motor is one of the main components of an electric vehicle. The operation of the motor is to convert the electric energy stored in the battery into kinetic energy to drive the vehicle. At present, electric vehicle drive motors appearing on the market are roughly divided into the following types: AC asynchronous motor (frequency conversion speed regulation), permanent magnet synchronous motor, DC brush motor, switched reluctance motor (SRD), etc., these ...
