ELECTRIC MACHINE WITH CONSTANT MAGNETS

摘要

An electric machine with constant magnets has a stator with a winding, a rotor with a layer of constant magnets located inside the stator, separated from the stator by an air gap and mounted on a shaft, elements of stator construction located coaxially to the rotor. Coaxially to the rotor at list on one end face ferromagnetic disks are located at a distance which is more than the air gap. The external diameter of the disks is not less than the rotor diameter; internal diameter of said disks is not more than the internal diameter of the layer of constant magnets.
