ELECTRIC MOTOR Russian patent published in 1994 - IPC

FIELD: electrical engineering. SUBSTANCE: electric motor includes stator with winding and rotor with space filled with ferromagnetic dispersing filling agent put on shaft anchored in frame. Rotor is manufactured from nonmagnetic material. Rotor space is divided into tight chambers uniformly located over circumference of rotor and filled with dielectric fluid. Elements of ferromagnetic dispersing filling agent are produced from heavily magnetized anisotropic material. Biggest size of these elements should not exceed value 0.01 of pole pitch of rotor. EFFECT: enhanced operational characteristics. 8 cl, 4 dwg
