Motor controller test method, device and equipment and storage medium

Abstract

The invention discloses a motor controller testing method, device and equipment and a storage medium, and the method comprises the steps: controlling a battery simulator to invert the power supply of a power grid into high-voltage direct current when a motor controller is in an electric state, and inverting the high-voltage direct current into three-phase power through the motor controller; enabling the three-phase electric drive motor simulator to simulate the electric condition of the motor and feeds back electric data; when the motor controller is in a power generation state, converting the battery simulator to invert power supplied by a power grid into high-frequency direct current, inverting the high-frequency direct current into three-phase power through the motor controller, enablinf the three-phase power to drive the motor simulator to simulate the power generation state of the motor, and feeding back power generation data; controlling the upper computer to analyze the electric data and the power generation data, wherein the motor controller test system is configured and managed according to an analysis result; and simulating the working state of a real motor under the same condition, and therefore, the data accuracy and the test efficiency in the development process of the motor controller are improved.

Description

technical field [0001] The invention relates to the technical field of motor testing, in particular to a motor controller testing method, device, equipment and storage medium. Background technique [0002] At present, the general vehicle motor controller test is carried out on the motor performance bench, and the real motor is tested by the dynamometer to detect the performance of the controller and collect corresponding data and safety performance tests; this test method is expensive and time-consuming. Due to limitations such as length and large footprint, and it is difficult to simulate loads with more degrees of freedom, the development and testing of motor controllers for each project requires corresponding test motors to cooperate with the test. Problems with motors and motor controllers will cross-affect, which is easy to cause detection Hidden dangers such as defects and electromagnetic interference need to pass a large number of verification tests; in addition, the ...
