Abstract:
In one embodiment, system for driving an electromagnetic appliance includes an electromagnetic appliance, a main-drive unit and a sub-drive unit. The electromagnetic appliance includes coils for n number of phases, the coils for each of the n phases being arranged in a pair and wound so as to be excited in a predetermined direction by being energized with opposite-phase currents. The main drive unit is connected to each of the coils and energizes the paired coils with opposite-phase currents. The sub-drive unit is provided parallel with the main-drive unit and is configured to suppress a short-circuit current occurring at the main-drive unit when switching energization of the coils.
