Problems solved by technology

[0003] In the current efficiency test of the motor, the actual speed of the motor under different loads is often used to reflect, and the adjustment of the load is mostly reflected by the change in the friction force of the motor rotation, in which the friction force of the motor is the friction plate Produced by contact and extrusion with the friction plate, the contact friction between the friction plate and the friction plate in the existing equipment will generate high temperature, which will affect the magnitude of the friction force between the friction plate and the friction plate, resulting in errors in the test data of the existing equipment. The disc and the friction disc will wear out after long-term work, which will cause the gap between the friction disc and the friction disc to become larger, which will affect the error of the test data of the motor by the equipment
