There are two torques the torque to raise the load and the torque to lower the load. So when starting a stepper motor, acceleration and deceleration should happen through pulses to the motor that start slowly and gradually quicken in a process called ramping. We’ll try to revisit this topic in future posts. Low Efficiency – Unlike DC motors, stepper motor current consumption is independent of load. There is no simple answer to this, and the options are usually: a) follow someone elses build and copy theirs; b) take a guess and try again if you are wrong; or c) work it out, which is the subject of this tutorial. The motor's position can then be commanded to move and hold at one of these steps without any position sensor for feedback (an open-loop controller ), as long as the motor is carefully sized to the application in respect to torque and speed. If 1" takes 8s, and the motor is rotating at 0.8RPS, then one revolution gives 0.156" travel (is this a metric lathe?).
