BRUSHLESS TORQUE MOTOR Russian patent published in 2019 - IPC H02K29/06 H02K1/06 

FIELD: electrical engineering.

SUBSTANCE: two belt sections with transverse cuts are placed coaxially along the rotor axis in the gap between the rotor magnet and the magnetic conductor. Both sections are mounted directly on engine housing, providing better heat removal. On the tapes, from which the sections are wound, there are both main and additional transverse cutouts ensuring the required flow of distributed current creating the motor torque with minimum pulsations. Rotor magnet has a pole overlap factor of 0.5, the length of the main and additional cutouts should be equal to 0.9 of the band width. Additional cutouts are located at the distance of one-third of the length of the section limited by two adjacent main cuts, and the band width is 1.2 of the length of the said section. Beginning and end of tape of each section through reverse switches are connected to switches, which are controlled by signals of rotor position sensor.

EFFECT: technical result consists in expansion of arsenal of brushless torque motors with simultaneous increase of developed moment and reduction of its pulsations.
