Electric machines simulation with QuickField
... To find the actual value of the secondary winding voltage the displayed parameter should be multiplied by the number of the secondary winding turns. This gives the secondary winding voltage with no load: 200 ⋅ 0.253 = 50.6 V. Please, refer to the QuickField problem in the “transformers” folder. ...

Stepper motor
![](https://commons.wikimedia.org/wiki/Special:FilePath/StepperMotor.gif?width=300)
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.
