摘要： The invention relates to electrical engineering and electric machines with stator-mounted magnets, and can be used in electric drives for machines and mechanisms as well as in electric power generators. A brushless machine contains a rotor comprising a shaft and at least one toothed fragment thereon, said toothed fragment having teeth positioned along the boundary of a gap. A stator comprises a toothed magnetic core and a winding, the coils of which are placed in the slots of the magnetic core of the stator. A multipolar magnetic system is made of a hard magnetic material, positioned between the rotor and the magnetic core of the stator, affixed to the stator and magnetized in such a way that an equal number of alternating opposite poles are arranged on the surfaces of the stator teeth, which teeth face the gap along the direction of rotation of the rotor. The stator is in the form of a solid of revolution with a plurality of teeth positioned along the axis of rotation of the rotor. Each coil of the winding is placed in one stator slot. Only the teeth of one toothed fragment of the rotor are positioned over each stator tooth. The number of teeth on each of the toothed fragment equals half of the number of poles found on a single stator tooth. The essence of the invention consists in increasing the power density of an electric machine and decreasing the mass of active materials.
