PERMANENT MAGNET MOTOR Russian patent published in 2013 - IPC H02K29/00 H02K21/12 

FIELD: engines and pumps.

SUBSTANCE: proposed permanent magnet motor consists of n equal modules, each of which includes a housing, a stator with phase windings, a rotor with constant magnets, which are magnetised in radial direction. Similar phase windings of adjacent modules are connected in series, housings and rotors of modules are connected to each other mechanically, and each module includes circular orientation elements of the stator with phase windings and rotors. At that, according to this invention, in each rotor, one half of magnets is offset relative to the other half in a circumfenertial direction by the half of the tooth division of stator t_zs, and in adjacent modules, similar magnets of rotors are offset in a circumferential direction through value t_zs/(2n).

EFFECT: improvement of start-up properties of permanent magnet motor owing to reducing pulsations of reactive moment; providing reliable connection of modules and permanent magnet motor as a whole.
