Abstract

The invention discloses a testing device for a stepping motor. The testing device is composed of a stepping motor positioning assembly, a torque sensor and a servo motor. The stepping motor positioning assembly is used for fixing a stepping motor; and the servo motor is used for transforming a voltage signal into a torque. One end of the torque sensor is connected with the stepping motor and the other end is connected with the servo motor. The torque sensor collects a physical change of the torque at the stepping motor and transforms the physical change into an electric signal. With the testing device, a problem of low manual testing efficiency of the stepping motor in the prior art is solved.

Description

technical field [0001] The invention relates to the field of automatic testing, in particular to a testing device and method suitable for stepping motors. Background technique [0002] At present, the inspection of stepping motors in the prior art adopts the method of testing the winding resistance with a multimeter, and at the same time measures the voltage of the stepping motors. For example, the deceleration permanent magnet stepping motor uses the stepping motor to test the power supply to calibrate the output voltage of the instrument every day. That is to say, use a multimeter to calibrate the common line and each phase voltage at the output end of the stepping motor test power supply within 12±0.1V, and make relevant records. Such as phase B proofreading: the red pen of the multimeter measures the pin corresponding to the black terminal lead of the power supply, and the black test pen measures the pin corresponding to the B phase lead of the power supply. The 12.01V m...
