INDUCTOR TWO-PHASE NON-REVERSIBLE MOTOR Russian patent published in 2009 - IPC H02K19/10 H02K1/06 

FIELD: electrical engineering.

SUBSTANCE: present invention relates to electrical engineering and is meant for use in electric actuators of mechanism with varying capacity, for example in fans, pumps, compressors, etc. The inductor two-phase non-reversible motor has a salient-pole symmetrical stator (1) with concentrated windings, and a ferromagnetic rotor (2). The stator (1) is made with 2m=4 pole terminals and the rotor (2) is made with 2(m ± 1) pole terminals, with beak shaped projections pointing in the direction of movement of the rotor. According to the invention, the beak shaped projections have a triangular opening (7), the base of which is parallel the outer side of the projection. The pole terminals of the stator have a triangular opening (8), the base of which is parallel the inner side of the stator. The length of the beak shaped projections is equal to the width of the pole terminals of the stator.

EFFECT: increase in torque of the inductor two-phase non-reversible motor, as well as reduced vibrations and emission of sound waves during operation is achieved due change in the shape of the magnetic core of the motor, leading to increase in the azimuth component of interacting forces of the stator and the rotor, and decrease in the radial component, which leads to deformation of the core and, consequently, vibration and sound radiation.
