... A single phase transformer is generally used to step-up or step-down the secondary voltage. This depends on the turn-ratio. For example, if the turn-ratio is 10, then the secondary voltage is less than the primary voltage by 10, and therefore the transformer is called a step-down transformer. The p ...

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.
