<p>In the stator of the electric motor, the windings (16) are disposed in two groups (16a, 16b) wound according to opposite current directions. Each group of windings is formed by a plurality of coils. The motor comprises a rotor speed commutator device (18-23) adapted for selectively cutting out current supply to at least one coil (16'a, 16'b) of each group of coils. The motor comprises an electronic circuit adapted for allowing sequential current supply to all of the motor coils during the initial starting rotation of the rotor assembly and allowing current supply, once the motor has reached its predetermined nominal speed, only to those coils which have been selected by the commutator device. <IMAGE></p> |
