Problems solved by technology

[0003] At present, the design idea of ​​the existing motor control device for electric vehicles is derived from the motor control device of the train. Due to the relatively large capacity and carrying capacity of the train, it is not necessary to modify the internal structure of the motor control device. Reasonable layout makes the motor control device relatively large in size and heavy in weight

Embodiment Construction

[0023] The present invention will be further described below in conjunction with accompanying drawing.

[0024] figure 1 A motor control device 10 for an electric vehicle according to the present invention is shown. The motor control device 10 is mainly used to control the torque and forward and reverse rotation of the motor, so as to make the electric vehicle move accordingly.

[0025] Such as figure 1 with figure 2 As shown, the motor control device 10 includes a detachably connected base 1 and a top cover 7 , and a container cavity 5 formed in the base 1 and the top cover 7 . The housing of the motor control device 10 composed of the base 1 and the top cover 7 can be roughly configured as a cuboid. The detachable connection between the base 1 and the top cover 7 is preferably realized by bolts. The shell can be casted from aluminum alloy material so as to be suitable for mass production, thereby saving cost, improving product quality, shortening production cycle and i...

Abstract

The invention relates to a motor control device used for an electric automobile. The motor control device used for the electric automobile comprises a base, a top cover and a container cavity, wherein the base and the top cover are detachably connected, and the container cavity is formed in the base and the top cover. A power module and a capacitor are arranged at the bottom in the container cavity. A control board contained in the container cavity is arranged above the power module and the capacitor. A wire holder is arranged on the upper surface of the control board. The power module and the capacitor are connected with the wire holder through a busbar. Compared with the prior art, the motor control device used for the electric automobile is smaller in size and lower in weight. Meanwhile, the motor control device which is small in size and low in weight can reduce the load of the electric automobile and improve the flexibility of the electric automobile.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a motor control device for electric vehicles. Background technique [0002] As environmental protection and energy issues become more and more serious, the state has begun to increase support for the electric vehicle industry, thereby promoting the rapid development of electric vehicles, and at the same time promoting the early entry of electric vehicles into thousands of households.
