Assessment to Study of Voltage Unbalance Effects about Efficiency
Assessment to Study of Voltage Unbalance Effects about Efficiency

... In recent papers, [1], [2] and [4], the authors have concluded that the efficiency and power factor of the motor depend on the positive sequence voltage, the negative sequence voltage, the voltage magnitude and the voltage angle. Likewise, these authors show that the derating factor given by the NEM ...

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.
