... around 5%. This makes it possible to draw larger pulse currents while limiting the total power in the pulse load resistor and MOSFET. A pulse width of around 150µsec is sufficient to see the full voltage sag and recovery in most DC/DC converters, so the PWM frequency can be set at around 330Hz. ...

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.
