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.

Brushless electric motor with self starting asymmetry

The invention provides an electrical machine having an inductor and an armature at least one of which has at least two independent winding assemblies. The switching into and out of circuit of each winding assembly is controlled by a processor which receives monitoring parameters of the machine and desired value parameters, thereby controlling in real time the operating characteristics of the machine. The machine may be a wind-driven generator.

Electrical machine having controlled characteristics and its application

A tubular stator capable of creating a magnetic field having both linear and rotary components comprises a tubular magnetic frame formed from longitudinal magnetic elements which are angularly spaced. The magnetic elements have teeth which extend radially inwardly. Circular induction coils are disposed between the teeth and undulating coils are disposed longitudinally between the magnetic elements. A magnetic sleeve surrounds the magnetic frame. An electric motor comprises a cylindrical rotor mounted within the tubular stator so as to be rotatable and translatable.
