New energy motor load test system

Abstract

The invention discloses a new energy motor load test system in the technical field of motor testing. The new energy motor load test system comprises a test platform, an adjusting base, a test frame and a load adjusting assembly; a test motor is mounted on the adjusting base, and the adjusting base can be adjusted in a front-back sliding manner to adaptively mount different types of motors; and the load adjusting assembly is arranged between the transmission rods, real-time pressure regulation and control are performed on the extrusion part through the pressure regulation and control part, load pressure buffer application is performed on one end of each transmission rod by the extrusion part, and loading force loading is performed on the test motor by the load adjusting assembly through friction force. The new energy motor load test system is suitable for carrying out load test on the new energy motor; Through the test system, data such as temperature rise, noise and rotating speed of the new energy motor under different loads can be obtained, the load adjusting assembly adjusts and controls friction force through oppositely arranged friction plates, linear adjustment of load force is implemented, and load modification can be carried out without shutdown.

Description

technical field [0001] The invention relates to the technical field of motor testing, in particular to a new energy motor load testing system. Background technique [0002] The motor drive control system is the main execution structure in the driving process of new energy vehicles. The fuel cell vehicle FCV, hybrid vehicle HEV and pure electric vehicle EV in the new energy vehicles all use electric motors to drive the wheels to drive the existing motor test system. [0003] For the general new energy motor load test, the motor under test is loaded with a certain amount of load for a long time, and the data of the motor is monitored in real time. In real-time adjustment, the reloading of the load can only be carried out after stopping the operation, which makes the whole test process cumbersome, and the adjustment range of the load is limited, and the linear load regulation needs to be solved urgently. For different types of motors, for example, for different The size and h...

[0003] For the general new energy motor load test, the motor under test is loaded with a certain amount of load for a long time, and the data of the motor is monitored in real time. In real-time adjustment, the reloading of the load can only be carried out after stopping the operation, which makes the whole test process cumbersome, and the adjustment range of the load is limited, and the linear load regulation needs to be solved urgently. For different types of motors, for example, for different The size and height of the motor need to be connected with the transmission shaft at the load end according to the position of the motor output shaft. Adaptive adjustments are required for the position of the fixed motor rack. Usually, a separate design of the test platform is required, resulting in a large amount of research and test resources. waste, based on this, the present invention designs a new energy motor load test system to solve the above problems
