ABSTRACT:
A dc electric motor having a rotor and a stator and at least a pair of oppositely disposed main magnets associated with one of the rotor and stator and including an end diverting magnet positioned at each end of each main magnet. The diverting magnets have a magnetic field perpendicular to the magnetic field of the main magnets and are oriented to increase the flux density of the main magnets with low magnetic leakage. Preferably, the main and diverting magnets are arcuate shaped segments of approximately 120.degree.. In addition, an interpolar diverting magnet may be positioned on both sides of each main magnet.
