Tips: Stepper motor lost and out of step
Electric motor misalignment means out of step, and out of step is divided into lost step and overstep. When the stepper motor is working normally, it moves a step angle every time it receives a control pulse, that is, one step forward. If the control pulse is continuously input, the motor will continuously rotate accordingly. When the motor loses steps, the number of steps the rotor advances is less than the number of pulses; when the motor generates oversteps, the number of steps the rotor advances will be significantly more than the number of pulses.
If the stepper motor is improperly selected, the motor torque is not enough or the inertia of the object movement exceeds the motor's self-locking force, it will cause loss step or out of step. Or the driver selection is improper, and the matching driver current is too small, which affects the normal operation of the motor. The rated current of the stepper motor driver should be greater than 1.2 to 1.5 times the rated current of the motor.
