FACE ELECTROMAGNETIC MACHINE (VERSIONS) Russian patent published in 2008 - IPC H02K26/00 H02K21/24 

FIELD: electricity.

SUBSTANCE: invention is related to the field of electrical engineering, namely - to slow-speed electric machines and electric drive. Suggested face electromagnetic machine contains stator with toroidal magnetic conductor and coil winding, disk rotor with permanent magnets with axial magnetization and alternating polarity, bearings and shaft. At that according to this invention stator is rigidly fixed in shaft, and rotor rotates in bearings in relation to axis of shaft, number of coils in coil group of stator b = 2, 3, 4, 5... - integral positive number that is more than or equal to 2, and number d of coil groups in phase, number z of stator teeth and number p of rotor poles pairs are connected with the following ratios: 1 < z/p < 4, at that z/p ≠ 2, and p/d = k, where k = 1, 1.5 , 2 , 2.5 , 3 , 3.5... - integral positive number, or number that differs from it by 0.5, if k is integral number, windings of coil groups in every phase are connected in accord, and if k differs from integral number by 0.5, at that windings of coil groups in every phase are connected back-to-back. According to the second variant of this invention implementation, rotor of suggested face electromagnetic machine consists of two disks with permanent magnets that face stator.

EFFECT: creation of efficient face electromagnetic machine.
