Description

TECHNICAL FIELD

[0001] The application relates to the technical field of motor inspection, and in particular to a motor inspection device and a use method thereof. BACKGROUND

[0002] Electric machinery, commonly known as a motor, is an electromagnetic device for realizing electric energy conversion or transmission according to the electromagnetic induction law. The motor generally comprises a stator and a rotor. The stator comprises a stator core and a coil winding wound on the stator core. The rotor comprises a rotating shaft and a rotor core sleeved on the rotating shaft. A permanent magnet is arranged at the outer edge of the rotor core. The motor is generally divided into a direct current motor and an alternating current motor. The motor is represented by the letter M in the circuit. The main function is to generate driving torque, and it is used as a power source for electric appliances or various machines. According to the type of working power source, the motor can be divided into a direct current motor and an alternating current motor. According to the structure and working principle, the direct current motor can be divided into a brushless direct current motor and a brushed direct current motor. The brushed direct current motor can be divided into a permanent magnet direct current motor and an electromagnetic direct current motor. The electromagnetic direct current motor is divided into a series excited direct current motor, a parallel excited direct current motor, a separately excited direct current motor and a compound excited direct current motor. The permanent magnet direct current motor is divided into a rare earth permanent magnet direct current motor, a ferrite permanent magnet direct current motor and an aluminum-nickel-cobalt permanent magnet direct current motor.

[0003] The torque of the motor is the output torque, which is one of the basic parameters. In order to ensure the quality of the motor, the output torque of the motor must be tested before the motor is shipped. Unqualified products are selected out, and the motor performance test, mechanical environment test and climate environment test are required. When the motor performance test is performed on the motor, the motor dynamometer is used to perform the no-load test, load test, maximum torque and minimum torque test, starting torque and starting current test and the like on the motor. The main purpose of these tests is to investigate the heat resistance grade, output capacity, service life and adaptability of the motor under abnormal working conditions. When the sampled motor is tested, the motor shaft is concentric with the shaft coupling on the motor dynamometer, and then the motor shaft is inserted into the shaft coupling. Then the motor is fixed by using the motor fixing device. After the shaft coupling is tightened, the motor can be tested.

[0004] The prior art discloses a motor torque testing device, publication number CN112362207A, which includes a worktable and a support and fixing mechanism. A through groove is formed on the worktable, and the support and fixing mechanism is located in the through groove. A first mounting seat is provided in the middle of the worktable. A bearing seat is provided at the left end of the first mounting seat, and a second mounting seat is provided at the right end of the first mounting seat. A speed and torque sensor is fixed on the first mounting seat, a shaft connector is provided on the bearing seat, and a magnetic powder brake is fixed on the second mounting seat. The present invention changes the distance between the first arc-shaped clamping seat and the second arc-shaped clamping seat by moving the slider in the groove, which facilitates the clamping and fixing of motors of different sizes and models. The vibration generated during motor operation is reduced by the shock-absorbing spring and sponge column, thereby increasing the accuracy of the test.

[0005] When connecting the tested motors to the motor dynamometer, workers need to load each motor individually, requiring a significant amount of time for assembly before each test. Similarly, replacing a motor requires considerable time to loosen the bolts in various locations, resulting in extremely long testing times, cumbersome motor replacement operations, and hindering rapid motor production.
