ABSTRACT:
A direct current, brushless, biphase motor with four unipolar windings and electronic drive, presents a geometry of the teeth and of the magnet generated field so that in each winding a trapezoidal e.m.f. is generated to allow the electronic drive to feel or sense the best switching point on the oblique side of such trapezoidal wave without the use of Hall probes; the two phases are embodied to obtain conduction on 180.degree. per winding, thus as two single-phases in parallel; the two single-phases may be embodied in a different way to permit the electronic selection of the use of three distinct motors in the motor: first single-phase, second single-phase and third biphase.
