Abstract

The invention relates to the technical field of permanent magnet motor testing, in particular to a permanent magnet motor manufacturing performance testing system and method.The permanent magnet motor manufacturing performance testing system comprises a base plate installed on an existing platform, a horizontally-arranged top plate is arranged above the base plate, and the top plate is fixed to the base plate through four supporting vertical plates; sliding platforms are arranged on the base plate and located on the left side and the right side of the top plate, a lifting device is arranged on the top plate, and a detection device used for detecting torsion of a motor output shaft is arranged on the right side of the top plate. Through cooperation of the sliding platform and the lifting platform, the function of assembly line type performance testing of the permanent magnet motor can be achieved. The clamping unit is mainly used for clamping and fixing the permanent magnet motor and moving and carrying the permanent magnet motor on the sliding platform and the lifting platform. The motor output shaft and the butt joint can be quickly inserted through the butt joint mechanism, meanwhile, butt joint of motor output shafts of different specifications can be achieved through second spline shafts of different specifications, and the application range of the motor output shaft butt joint device is widened.

Description

technical field [0001] The invention relates to the technical field of permanent magnet motor testing, in particular to a permanent magnet motor manufacturing performance testing system and method. Background technique [0002] The permanent magnet motor uses permanent magnets to provide excitation, which makes the motor structure simpler, reduces the processing and assembly costs, and saves the slip rings and brushes that are prone to problems, which improves the reliability of motor operation; and because no excitation current is required , There is no excitation loss, which improves the efficiency and power density of the motor. The motor transmits torque through the output shaft. Therefore, the motor needs to test the output shaft torque of the motor during production to ensure that the output shaft torque meets the specified requirements. [0003] In the prior art, such as a motor output shaft torque testing device provided by publication number CN211477471U, it include...

Problems solved by technology

[0004] In the above prior art, the T-shaped sliding seat has a certain height from the bottom plate, so the motor needs to be transported to the T-shaped sliding seat. When the motor to be tested is large When the gravity is heavy, it is difficult to transport, while the traditional transport method is mainly lifted by manual or existing hoisting equipment, and its loading and unloading are slow, which affects the test efficiency; at the same time, the motor needs to be adjusted after it is transported to the T-shaped slide. position to ensure that the motor can be connected to the torque sensor, it will take a lot of time to adjust the position of the motor, which further affects the efficiency of the motor test; at the same time, the output shaft of the motor is connected to the torsion sensor through a coupling, so every time the motor is tested The output shaft needs to be connected to the coupling, and the output shaft and the torque sensor are not quickly connected to reduce the test time; and when the diameter of the output shaft is different for motors of different specifications, different couplings need to be replaced The device can be connected, which further affects the test efficiency of the motor
