VALVE MOTOR WITH INTEGRATED ROTOR ANGULAR POSITION SENSORS Russian patent published in 2019 - IPC H02K29/08 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the electrical equipment. Valve motor with integrated rotor angular position sensor contains electronic control unit, stator with number of teeth z_st=m⋅k⋅t, where m is the number of phases of the stator winding, k is the number of coil groups in the phase, n is the number of coils in the coil group, each of which consists of successively – oppositely connected coils covering each stator tooth. Coil groups of each phase, when n is even, are interconnected oppositely, and when n is odd and m is three, it agrees. Rotor is made with alternating polarity poles made of radially magnetized permanent magnets mounted on a magnetic core, the number of which is 2p=z_st±k. Hall sensors are used as sensors of the angular position of the rotor. Hall phase sensor at n even is installed in the stator slot, located on the symmetry axis of the coil group of the corresponding phase, and when n is odd in the next phase groove group closest to the symmetry axis of the coil group. Each phase contains an additional Hall sensor mounted from the main Hall sensor on the symmetry axis of the coil group of this phase on the number of teeth divisions in the range from 1 to z_st/2k.

EFFECT: technical result consists in increasing the efficiency.
