application considerations for high resistance ground
application considerations for high resistance ground

... A. 480 V Grounded Circuits The retrofit of existing equipment to establish a high resistance grounding system is a simple process that can be completed in several steps. First, determine the status of the existing system. If the existing system is solidly grounded and it is desired to obtain the ben ...

... conduction. Turn-off must be achieved in the anode-to-cathode circuit. There are three ways in which turn-off, or commutation as it is commonly called, can be achieved by: (1) reversing the anode-to-cathode voltage; (2) reducing the anode current below the holding current level; (3) forcing current ...

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.
