Abstract (en)
At least two sets of driving coils of the same individual electromagnetic actuating device of the present invention in parallel connection or series-parallel connection to appear relatively lower impedance being electrified to obtain larger actuating force is further manipulated by the switching device to be switched to series connection and series-parallel connection to appear relatively higher impedance thus reducing currents passing through driving coils, while required operating characteristics of the electromagnetic actuating device can still be satisfied.
