  • Publication number: 20140184131
    Abstract: Disclosed herein are a method and apparatus of controlling a switched reluctance motor (SRM). The method of controlling driving of an SRM, the method includes: sensing a variation of a load of the SRM; and controlling both of a dwell angle and a PWM duty ratio of the SRM according to the variation of the load of the SRM. Therefore, an angle and a current are simultaneously controlled, thereby making it possible to decrease a torque ripple at a low speed and constantly control a torque and rapidly respond to a command speed at a high speed. In addition, a speed and a torque of the SRM may be more precisely controlled.

  • Publication number: 20130285584
    Abstract: Disclosed herein are a motor driving apparatus and method. The motor driving apparatus includes: an inverter including a main driver sequentially activating N phases and a spare driver activating a spare phase substituting for a faulted phase among the activated N phases; a detecting unit detecting the respective output signals of the N phases; a switching unit performing switching so that the spare phase is connected to the faulted phase of the exited N phases; and a controlling unit driving the inverter to determine whether or not a fault is generated and control the switching unit so that the faulted phase is connected to the spare phase. Therefore, since the motor may be driven without replacing the inverter, a cost may be reduced, and since the motor may be driven without a change in the number of phases, the motor may be efficiently and stably driven.
