Abstract

The invention relates to a torque motor torque fluctuation coefficient detector and a detecting method and belongs to the technical field of torque motor torque fluctuation measurement. The torque motor torque fluctuation coefficient detector and the detecting method solve the problems that during the process of measuring force from a stator to a sensor, existing torque motor torque fluctuation coefficient detectors are unreliable in detected results due to gravity interference of the stator. The detector comprises a dynamometer, a calibration assembly, a first coupler, a torque motor to be measured, a chuck mechanical arm, a load bearing, a second coupler, a position adjusting base, a stepping motor, a stabilizing base, a singlechip and a computer. The detecting method comprises the steps of firstly performing initial calibration; then adjusting the chuck mechanical arm to firmly clamp a stator of the torque motor to be measured; powering up the torque motor to be measured to enable the torque motor to be measured to generate torque, then enabling the torque motor to be measured to be under a lock rotor state; and finally driving the stator of the torque motor to be measured by the stepping motor to rotate a circle, synchronously collecting torque signals, and outputting the torque signals to the computer. The torque motor torque fluctuation coefficient detector and the detecting method are suitable for detection of torque motor torque fluctuation coefficients.

Description

technical field [0001] The invention relates to a torque motor torque fluctuation coefficient detector and a detection method, belonging to the technical field of torque motor torque fluctuation measurement. Background technique [0002] With the progress and development of modern science and technology, torque motors have been widely used in many fields such as machinery manufacturing, automatic control, aerospace and national defense. The practice of production and scientific research requires that the torque motor has high reliability, stability, controllability, energy saving and environmental protection. In terms of smooth operation, the torque fluctuation of the motor is required to be small. Therefore, in the detection process of the torque fluctuation of the motor, How to improve the practicability and reliability of detection tools is a very critical issue. [0003] At present, traditional dynamometers are still widely used in my country to test the performance of ...
