  • Brushless electric motor with self starting asymmetry
    Patent number: 4940912
    Abstract: The motor includes a rotor (2) with permanent magnets and a stator (3) that surrounds the rotor and includes reluctance pads (9, 10) provided to place the rotor (2), upon stopping, in a position where the startup of the motor will be assured. The reluctance pads (9, 10) are asymmetrical with respect to the magnetic axis (A) of the coils of the stator (3) and include notches (4), at least some of which serve to accommodate at least one coil of the stator (3), in order to assure obtaining a maximum winding coefficient.
