"DIRECT CURRENT MOTOR HAVING OUTER ROTOR AND INNER STATOR" ABSTRACT OF THE DISCLOSURE 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 outward 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 comprises a rotatable cylindrical cage positioned concentrically around the stator. The cage supports cir- cumferentially spaced rows of longitudinally aligned spaced magnetic inserts which are positioned to register with the stator rings. 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.
