... In the 1970’s when automobiles would disrupt radios as they drove nearby, it was due to the spark plugs drawing an arc from the collapse of the magnetic field of the coil. The magnetic fields will collapse with a factor of E = L di/dt. A side affect is that any energy not recovered results in heat o ...

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.
