MODULAR MACHINE FOR GEAR-FREE HIGH-TORQUE DRIVE Russian patent published in 2020 - IPC H02K16/00 H02K11/30 

FIELD: electrical equipment.

SUBSTANCE: invention relates to the electrical equipment. Modular machine consists of N modules, which are electric motors made using permanent magnets or short-circuited rotors windings, and comprises housing common for all modules, on which protective shields are installed, module rotors located on common shaft, stators of modules with phase windings, each of which is connected to corresponding power electronic control unit with possibility of modules torque modulation by harmonic law: where M is amplitude value of torque; ω is shaft rotation frequency, rad/s; ϕ_k is phase shift, wherein angle ϕ_k depends on the number of modules N and is determined by formula: where k is module number.

EFFECT: technical result is providing high power and torque of drive.
