... Operation is pretty simple. You turn it on with the green rocker switch. The “Output Voltage” knob sets the source emf value; the “Output Current” knob sets the current limit value. Since you will be operating into essentially a short circuit, the voltage can be set at some low value, and output cur ...

Stepper motor



A stepper motor or step motor or stepping motor is a brushless DC electric motor that divides a full rotation into a number of equal steps. The motor's position can then be commanded to move and hold at one of these steps without any feedback sensor (an open-loop controller), as long as the motor is carefully sized to the application in respect to torque and speed.Switched reluctance motors are very large stepping motors with a reduced pole count, and generally are closed-loop commutated.
