Abstract
A rotor of T-shaped section lies on the motor shaft. The rotor comprises two external symmetrical collars which comprise radial magnetized permanent magnetic poles. Two identical stator parts, symmetrically arranged in the motor comprise external pole teeth lying external resp. internal of each of one of the collars of the motor. This gives rise to a radial flow of magnetic flux in the external lying, radially magnetized permanent magnetic poles of the rotor which leads to a high torque and efficiency. The construction of the motor is simple. Relatively thin material may be used. Relatively high number of poles are possible due to the fact that the effective poles, of the stator and of the rotor lie at the outside.
