Description

Technical Field

[0001] The present invention relates to the technical field of motor detection, and in particular to a motor torque detection device. Background Art

[0002] Electric actuators must be comprehensively tested before leaving the factory. For motors, especially stepper motors, the detection of starting torque and holding torque is an essential process in the motor detection process. Starting torque refers to the torque generated by the motor when voltage is applied to the motor in a stopped state. Holding torque refers to the torque of the stator locking the rotor when the stepper motor is powered but not rotating. It is one of the most important parameters of the stepper motor. Usually, the torque of the stepper motor at low speed is close to the holding torque. Since the output torque of the stepper motor continues to decay with the increase of speed, the output power also changes with the increase of speed, so the holding torque becomes one of the most important parameters for measuring the stepper motor. For this reason, it is necessary to use detection equipment to detect the motor torque.

[0003] After searching, the utility model patent with announcement number CN210833950U discloses a motor torque detection device, including: a base frame, a transmission shaft arranged on the top of the base frame and connected to the motor to be detected, a torque disk coaxially arranged with the transmission shaft, a gravity mechanism arranged below the torque disk, and a rope sleeved on the torque disk and connected to the gravity mechanism. The above-mentioned motor torque detection device can complete the measurement of the starting torque and holding torque of the motor through the gravity mechanism and the torque disk, while reducing the space occupied by the motor torque detection device.

[0004] However, when the existing motor torque detection equipment is in use, although it can detect the motor torque data by the lifting height of the torque disk and the gauge block, when the torque disk stops rotating, the synchronous self-locking effect on both sides of the torque disk is not high, so that after the torque disk stops rotating, the torque disk will rotate under the action of inertia, reducing the accuracy of the motor torque detection data, and when the torque disk is used to drive the rope to be lowered, the rope limit scaling effect is not high, which can easily cause the rope to deviate, affecting the continuity of subsequent motor torque detection, and does not meet people's use needs. For this reason, we propose a motor torque detection device. Summary of the invention
