FLANGED MULTILAYER TORQUE MOTOR Russian patent published in 2005 - IPC

FIELD: electrical engineering; electrical machines and drives.

SUBSTANCE: proposed motor characterized in great number of pole pairs has rotor assembled of several disks mounted on common shaft and provided with permanent magnets whose polarity is tangentially alternating, as well as toothed wound stators. Stators disposed on both ends of any rotor disk carry ring windings of one phase only installed in each stator coaxially with respect to rotor between two hollow cylindrical magnetic cores of different diameters. Butt-ends of hollow magnetic cores facing the rotor have teeth whose number equals number of rotor pole pairs; teeth of external and internal cylindrical magnetic cores are shifted through angle equal to angular width of rotor pole and on other butt end cylindrical magnetic cores are joined with magnetic core stacks assembled of radially disposed laminations. Stators of different phases are spaced apart through angle equal to 2π electrical degrees divided by number of phases.

EFFECT: simplified design, facilitated manufacture, reduced labor consumption and manufacturing cost.
