Single-Phase Transformers - Electrical and Computer Engineering
... As can be seen, primary taps at 120-V and 208-V are available using terminals H2-H3 and H4 respectively. In low-power single-phase residential applications, 120-V is a common voltage level. This is typically obtained by splitting a 240-V winding. Alternatively, 120-V can be obtained from the line-to ...

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.
