Embodiment Construction

[0021] Such as figure 1 As shown, this embodiment is a test device for testing the life of a motor. Using the device of this embodiment, the life test of two motors, that is, the first motor and the second motor, can be performed at the same time. In this embodiment, the testing device such as figure 1 Shown: It includes an industrial computer, a first controller to control the operation of the first motor, a second controller to control the operation of the second motor, the first controller and the second controller obtain the first The state of the first motor and the second motor. Torque speed measuring instrument and power analyzer; communication between the first controller and the first motor, and between the second controller and the second motor through the KWP2000 communication protocol. The transmission timing of information between the first controller and the first motor and between the second controller and the second motor is a fixed timing transmission method...

Abstract

The invention discloses a platform and a method for testing the life of motors, which are used for testing the life of a first motor and a second motor. The platform comprises an industrial control computer, a first controller for controlling the work of the first motor, a second controller for controlling the work of the second motor, a torque rotating speed measurer and a power analyzer; the first motor is coaxially connected with the second motor oppositely; the industrial control computer comprises two serial ports; the industrial control computer communicates with the first controller and the second controller through the two serial ports via a controller area network (CAN) bus; and the torque rotating speed measurer is arranged on a connecting shaft of the two motors, and a measuring result of the torque rotating speed measurer is output to the power analyzer. The platform capable of simultaneously testing the life of the two coaxially and oppositely connected motors by using the industrial control computer, automatically sending a test command to the controllers of the motors through the industrial control computer during testing, receiving, displaying and storing real-time tested information sent from the controllers is provided. The device has a simple structure and the method is easy, the test capability is enhanced greatly, and the labor intensity during testing is lowered.

Description

technical field [0001] The present invention relates to the field of motor testing, in particular to a platform for testing motor life and a testing method. The platform is a testing platform for motor life testing based on LabVIEW, especially for hybrid motors and pure electric vehicle motors. Develop tests. Background technique [0002] The driving motor in hybrid electric vehicle and pure electric vehicle system plays a very important role in the whole vehicle system, and its basic performance directly affects the performance index of the whole vehicle. Therefore, it is particularly important to conduct a sample life test on the motor to verify the reliability and performance indicators of its operation. [0003] At present, the life test of the motor is to simulate the operation of the motor in the actual road conditions, with equivalent strengthening, and to investigate the aging degree of the motor at the end of the test under these working conditions. For example, t...
