Abstract:
A method of driving a first brushless motor comprising a plurality of first phase windings each having first and second terminals wherein the second terminals are pre-connected to form a star or polygon configuration with an integrated driving system also for driving a second brushless motor comprising a plurality of second phase windings adapted to be independently driven by respective output full-bridges, the integrated driving system comprising at least one signal generator for generating a plurality of driving phase signals, a plurality of output full-bridges each comprising a pair of half-bridge stages wherein each of the half-bridge stages has an input and an output and is driven at its input by one of the plurality of driving phase signals, and a plurality of output pins each connected to a respective output, the method comprising:connecting each of the first terminals to one of the plurality of output pins relative to one of the plurality of driving phase signals and to another output pin relative to a different one of the plurality of driving phase signals; providing a plurality of signal path selectors at the inputs; and driving the plurality of signal path selectors to a predetermined position corresponding to the phase winding configuration of the first motor by crossing the paths of at least one of the plurality of driving phase signals directed toward the inputs.
