ABSTRACT:
The stator of the motor comprises a series of stator rings arranged in cylindrical fashion. Each stator ring is made up of a circular row of electromagnetic components, each component comprising a U-shaped core having two outwardly projecting poles and individual coils for each of the poles. The stator rings are positioned so that their electromagnetic components are offset rotationally from one ring to the next. The rotor is mounted to rotate outside the stator and comprises a plurality of longitudinally arranged magnetic elements circumferentially spaced around the stator. In operation, the stator rings are energized sequentially by suitable switching means to generate a torque in the rotor. The motor has capacity for variable speed and variable torque.
