Tips: Application of stepper motor in automobile test
The detection of many automobile brake components requires a stepper motor in the test system.
Since the angular displacement of the stepper motor is strictly proportional to the input pulse, there is no accumulated error during its movement and the follow ability is good. Therefore, the stepper motor is a better performing component in the automotive brake component test system. The system hardware consists of displacement sensor, force sensor, motor, and the control core adopts industrial computer and data acquisition card.
The hybrid stepper motor drives the ball screw through the coupling to form a force adding device. The force sensor is installed at the front end of the screw rod to measure the output torque of the motor and the "input force of the test piece". The industrial computer controls the start, advance, and back, stop, and control the speed of forward and backward according to the test program.
