Some exemplary reluctance motors disclosed herein comprise a rotor having a plurality of radially outwardly projecting rotor poles and a plurality of generally U-shaped stator units positioned circumferentially around the rotor. Each stator unit is spaced circumferentially apart and magnetically isolated from adjacent stator units. Each stator unit comprises a circumferentially extending yoke and two stator poles extending radially inwardly from the yoke, such that the stator poles are positioned adjacent to the rotor poles. The motor further comprises a plurality of coils of electrical conductors, wherein each of the coils is coiled around a respective one of the yokes of the stator units. In some embodiments, non-magnetic stator supports are positioned between the stator units and configured to engage circumferential sides of the stator units to hold the stator units in radial and circumferential alignment with the rotor.
