ROLE OF VACUUM GENERATOR CIRCUIT BREAKER IN
... In some cases, an intentional delay up to 150 ms in the tripping circuit is used so that the DC component at the time of the contact separation reaches to a value that the circuit breaker will be able to interrupt the fault current quickly. But it is not recommended using the delayed tripping since ...

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.
