The difference between the five-motor bench and the four-motor bench of the whole vehicle

Five-motor bench and four-motor bench are bench equipment used for automobile power system testing, and the difference between them lies mainly in the number of motors and testing ability.

The vehicle five-motor test-bed refers to the test equipment with five independent motors, which is used to simulate the vehicle power system. These motors are used to drive the front and rear wheels and the transmission system respectively, including two front drive motors, two rear drive motors and a transmission system simulation motor. By controlling the speed and torque of these five motors, the real road driving conditions can be simulated, and the performance of vehicle power system can be tested and evaluated.

Four-motor frame refers to the test equipment with four independent motors, which is used to test and evaluate the automobile electric drive system. These four motors are used to drive the front wheel and the rear wheel respectively, and are divided into two front drive motors and two rear drive motors. By controlling the speed and torque of these four motors, we can simulate the real driving conditions and test the performance of the electric drive system.

Therefore, compared with the four-motor frame, the test ability of the five-motor frame of the whole vehicle is more comprehensive, and the power system of the whole vehicle can be evaluated more comprehensively. However, in practical application, it is necessary to evaluate and decide which bench equipment to use according to the specific test requirements and budget.
