Description

technical field [0001] The invention belongs to the field of moment measurement, in particular to a torque meter-based micro moment measurement device. Background technique [0002] Dynamic performance parameters such as gyroscope motor reaction torque, motor disturbance torque, and wave torque are important indicators to measure motor performance. At present, traditional micro-torque measurement devices are mainly based on strain-type measurement methods and force balance measurement methods. The strain type measurement method means that the measured torque is loaded on the measuring shaft of the torque sensor, the shear strain or shear stress generated by the corresponding system is measured, and the measured torque can be measured by collecting the output voltage of the sensor; the force balance measurement method means that the measured torque is loaded on the On the transmission shaft, the torque device applies counter torque to the transmission shaft according to the a...
