In accordance with the teachings described herein, a DC homopolar machine is provided. The DC homopolar machine may include a stator having a stator magnetic core and a permanent magnet, a rotor magnetic core supported within the stator to rotate relative to the stator, and non-magnetic material within a gap between the rotor magnetic core and the stator magnetic core. The stator, rotor and non-magnetic material form a magnetic circuit having a total reluctance, the total reluctance of the magnetic circuit being provided by a first reluctance of the permanent magnet and a second reluctance of the gap of non-magnetic material, with the first reluctance being substantially equal to the second reluctance.
