Working process of electric torque wrench

‌Motor drive‌: The electric torque wrench is powered by a motor. The motor usually adopts a DC motor, and its speed and power determine the working performance of the wrench. By controlling the speed and current of the motor, the torque can be adjusted and controlled. ‌Reducer conversion‌: The motor converts the torque of high speed and low torque into the torque of low speed and high torque through the reducer. The reducer usually adopts gear transmission or worm transmission, which can reduce the speed of the motor by dozens of times and amplify the torque by dozens of times. ‌Torque measurement‌: The torque sensor is used to measure the magnitude of torque. It usually adopts the principle of strain gauge, capacitive sensor or magnetic sensor to convert the torque into electrical signal output. Through the torque sensor, the magnitude of torque can be monitored and fed back in real time, so as to realize the precise control of torque. ‌Control system‌: The control system is the core part of the electric torque wrench, mainly including components such as circuit board, microprocessor and display. The control system can realize the precise control and transmission of torque by controlling the speed and current of the motor according to the preset torque value and angle value. At the same time, the control system can also save and output torque data for subsequent analysis and management.
