LINE ELECTRIC MOTOR Russian patent published in 1995 - IPC

FIELD: electrical engineering. SUBSTANCE: this line electric motor is designed for discrete electric drives. It is composed of multielement stator each element of which has magnetic core with poles and magnetizing coil and armature. Poles of stator and armature are manufactured in the form of magnetic rings bordering on air gaps alternating with nonmagnetic rings. Nonmagnetic rings of one element bulge out relative to its magnetic rings on diameters adjacent to air gaps by value of air gap combining function of plain bearings. Space between magnetic cores of magnetizing coils is filled with grease. EFFECT: enhanced operational safety. 3 cl, 2 dwg
