Abstract
An electric machine includes a stator having a phase arrangement, and a rotor. The phase arrangement includes legs connected in parallel at first and second primary junctions. Each leg includes a plurality of coils connected in series through a respective intermediate junction. Each leg is connected to at least one other leg by a branch at the respective intermediate junctions such that the phase arrangement is a bridge circuit. The phase arrangement conducts a motor current through the respective coils between the first and second primary junctions. The phase arrangement permits an alignment current to flow between the first and second primary junctions along an alignment current path which passes through at least one coil of two different legs via a respective branch. The motor currents cause a torque to be applied to the rotor, and the alignment current causes a translational force to be applied to the rotor.
