... of the resistance at full-load operation. It consists of two layers of bars, both short-circuited by end rings. The upper bars are small in cross-section and have a high resistance. They are placed near the rotor surface so that the leakage flux sees a path of high reluctance; consequently, they hav ...

... When a coil is formed of many wire turns, the magnetic fields around each wire add up to produce a strong electromagnet. One side of this magnet will be a North Pole while the other side will be a South Pole If the current in the electromagnet is reversed, the magnetic poles will swap sides. ...

Beware of Zero-Crossover Switching of Transformers
... Figures 3 and 4 show the effect of a 90o turn-on SSR on transformer inrush current. In Figure 3A, the transformer secondary is open, and the primary is turned on near zero voltage. A first half-cycle inrush of 200 amps occurs (read scope tracing right to left). However, when that same transformer i ...

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.
