Motor controller

Abstract

The invention provides a motor controller, which comprises a first driver board, a first main control board, a second driver board, a second main control board and an interface board, wherein the interface board is connected with the first main control board and the second main control board separately and inputs external bus signals into the first main control board and the second main control board through the interface board separately; the first main control board is connected with the first driver board and the first main control board outputs a first drive signal to the first driver board; the first driver board converts DC into AC according to the first drive signal and drives a first motor to rotate; the second main control board is connected with the second driver board and the second main control board outputs a second drive signal to the second driver board; and the second driver board converts the DC into the AC according to the second drive signal and drives a second motor to rotate. According to the motor controller, independent control on the motor is achieved, the volume of the motor controller is reduced and repairing, installation, maintenance and debugging are facilitated while the operation performance of the motor controller is improved.

Description

technical field [0001] The invention relates to the technical field of drive control, in particular to a motor controller. Background technique [0002] With the rapid development of the automobile industry and the improvement of the level of technology, the total number of vehicles in the world has grown rapidly. The increase in the demand for oil resources and the environmental problems caused by traditional fuel vehicles have increasingly attracted people's attention. In this case, the development of new energy vehicles and breakthroughs in related technologies have made it an inevitable trend for electric vehicles to replace traditional fuel vehicles, making the development of sustainable green vehicles possible. Electric vehicles have the advantages of no exhaust emissions, high energy efficiency, low noise, and recyclable energy during driving. The development of electric vehicles can effectively solve the problems of transportation energy consumption and environmental...

Problems solved by technology

[0003] see figure 1 As shown, the structure schematic diagram of the existing dual-motor driven electric vehicle, it can be seen from the figure that the controller hardware system control part is powered by a unified, if the power supply fails, it will cause the controller DSP main control chip to fail to work normally, resulting in The left and right motors cannot run at the same time, posing potential safety hazards; and there are too many internal connector connections, low reliability, high-voltage detection safety protection, and external connectors cannot be installed on the same side, which causes problems such as commissioning and maintenance, inconvenience, etc.
