DC MOTOR WITH SLIDING CONTACTS Russian patent published in 2017 - IPC H02K99/00 

FIELD: electricity.

SUBSTANCE: motor includes a stator and a rotor with the rotation axis and the sliding contacts of the ring type located thereon, enclosed in the folding case. As the stator, two ferromagnetic toroids of the magnetic material fortified to the casing, are used, placed respectively in the first and the second cylindrical coil, coaxial rotation axis. The coils are wound in the ferromagnetic stator toroids around the generators of these toroids. The rotor is designed in the form of the ferromagnetic toroid located between the ferromagnetic stator toroids and the third cylindrical coil fixed to the ferromagnetic rotor toroid. All coils are incorporated to the DC source in series so that the magnetizable ferromagnetic rotor toroid is unidirectionally mutually repelled from the magnetized ferromagnetic stator toroids. The coils, wound around the generators of the stator ferromagnetic toroids, are incorporated so that the magnetic fields, generated inside these ferromagnetic toroids, are unidirectional.

EFFECT: simplified design.
