Abstract

An electric motor is powered by either an AC or a DC source. The motor has fixed brushes and has a high efficiency due to the design overcoming contra-electromotive forces. The motor carcass (8) consists of a stack of laminations and houses a number of principle poles and auxiliary switching poles evenly distributed around the rotor. The two pole types are alternate in position and separated by small and large slots. The carcass also carries coil windings which are identical for both pole types, both sets of windings being connected in two parallel groups which become series connected during the motor operation cycle.
