... found that the closed-loop poles are located in the unit circle (according to Routh's stability criterion for discrete-time systems), which means that the closed-loop system shown in Figure 6 is stable. In other words, the system is safe. Figure 8a shows the experimental motor response using Equatio ...

... Other factors are also involved. When an external magnetizing force is applied it “moves domain walls” to make the stronger domains larger. It takes just as much energy to move these domain walls back to where they were, so a magnet that is hard to magnetize usually is hard to demagnetize. However, ...

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.
