Abstract
An electric machine includes a rotor, a first and second stator, a first and second plurality of permanent magnets, a first and second winding, a third and fourth winding. The first stator and the second stator are mounted axially relative to the rotor. A first permanent magnet and a second permanent magnet of the first plurality of permanent magnets have opposite polarities. A first permanent magnet and a second permanent magnet of the second plurality of permanent magnets have opposite polarities. The first winding, the second winding, the third winding, and the fourth winding are connected in series. An absolute value of an angle offset between the first winding and the third winding and between closest poles of the first plurality of poles and the second plurality of poles is 180 electrical degrees.
