Abstract

The invention discloses a motor torque testing device, which belongs to the technical field of motor testing and comprises a workbench and a supporting and fixing mechanism, a through groove is formedin the workbench, the supporting and fixing mechanism is located in the through groove, a first mounting seat is arranged in the middle of the workbench, a bearing seat is arranged at the left end ofthe first mounting seat, a second mounting seat is arranged at the right end of the first mounting seat, a rotating speed and torque sensor is fixedly arranged on the first mounting seat, a rotatingshaft connector is arranged on the bearing seat, and a magnetic powder brake is fixedly arranged on the second mounting seat. The distance between a first arc-shaped clamping base and a second arc-shaped clamping base is changed through movement of a sliding block in a sliding groove, motors of different types and sizes can be clamped and fixed conveniently, vibration generated during operation ofthe motors is reduced through the arranged damping springs and sponge columns, and the test accuracy is improved.

Description

technical field [0001] The invention belongs to the technical field of motor testing, and in particular relates to a motor torque testing device. Background technique [0002] The motor torque is the output torque of the motor, which is one of the basic parameters of the motor, especially the torque is an indispensable measurement in the motor efficiency evaluation. The accuracy of the torque measurement is directly related to the correctness of the motor efficiency evaluation. Due to the various types of motors, when different types of motors are tested on the same torque test device, the position of the motor to be tested needs to be readjusted and the shaft of a different type needs to be replaced. The operation is very troublesome, and the general motor test is suspended. Connected to the rotating shaft, there is no special fixing seat, and the vibration of the motor during operation will easily affect the measurement results. If a special fixing seat is installed, diffe...
