Abstract:
A motor including a stator, a first connector portion, a selector, and a second connector portion. The stator has a first winding arrangement configured for a first voltage and a second winding arrangement configured for a second voltage different from the first voltage. The first connector portion is selectively connectable to each of the first winding arrangement and the second winding arrangement. The selector is movable between a first position in which the first connector portion is connected to the first winding arrangement, and a second position in which the first connector portion is connected to the second winding arrangement. The second connector portion is electrically connected to a power supply and selectively engageable with the first connector portion to provide power to one of the first winding arrangement and the second winding arrangement.
