ABSTRACT:
In a rotary electric motor, a stator contains a plurality of separate electromagnet core segments disposed coaxially about an axis of rotation. The core segments are affixed, without ferromagnetic contact with each other, to a non-ferromagnetic support structure. The rotor is configured in a U-shaped annular ring that at least partially surrounds the annular stator to define two parallel axial air gaps between the rotor and stator respectively on opposite axial sides of the stator and at least one radial air gap. Permanent magnets are distributed on each inner surface of the U-shaped rotor annular ring that faces an air gap. A winding is formed on a core portion that links axially aligned stator poles to produce, when energized, magnetic poles of opposite polarity at the pole faces.
