- 1 - Abstract: A brushless induction motor comprises an eight pole three-phase stator winding, a four pole three-phase stator winding overlapping the eight pole three-phase stator winding, and a rotor winding facing and coaxial with the eight pole and four pole three-phase stator windings and formed of six unitary windings. The six unit windings are uniformly arranged with respect to the eight pole and four pole three-phase stator windings. Each unitary winding includes a coil having six turns. The first end terminals of the coils of six unitary windings are connected to a first end ring and the other end terminals thereof are connected to a second end ring. The rotating speed of the brushless induction motor is controlled by regulating an exciting current frequency applied to the four pole three- phase stator winding.
