Description

Technical Field

[0001] The utility model relates to the technical field of motor testing, in particular to a motor testing device. Background Art

[0002] With the development of industry, motors have become the most widely used core components in power sources. Motors are a kind of equipment that converts electrical energy into mechanical energy. They use energized coils to generate a rotating magnetic field and act on the rotor (such as forming a magnetic electromotive force to rotate the torque). However, before the motor leaves the factory, its performance detection is an indispensable step. Therefore, for a large number of motor performance tests, fast installation to improve efficiency and multi-functional use to save costs are also relatively important issues.

[0003] In the prior art, most designed motor test benches can only detect one corresponding motor. If you want to detect multiple motors, you need to design multiple matching motor test benches, which will greatly increase the testing cost. When the motor test bench is working, the output shaft of the test motor is connected to the input shaft of the torque sensor through a coupling, and the output shaft of the torque sensor is connected to the input shaft of the load motor through a coupling. The traditional motor test bench input shaft and output shaft are not easy to align when connected, which will make the motor test bench more difficult to install and increase the installation time. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the present utility model is to provide a motor testing device, aiming to solve the technical problems in the prior art that the motor test bench can only detect one corresponding motor and the input shaft and output shaft of the motor test bench are difficult to align when connected.
