ELECTRIC MOTOR
Document Type and Number:
WIPO Patent Application WO/2004/091957
Kind Code:
A1
Abstract:
The invention relates to electrotechnical and mechanical engineering, in particular to the structural embodiment features of electric motors, mainly for means of transport. Said invention is characterised in that the inventive electric motor consists of a rotor (3) provided with electromagnets (6), a stator (2) comprising a circular magnetic circuit (4) which is provided with an even number of permanent magnets (5) fixed thereto at an equal distance from each other, a distribution manifold (7) which is provided with conductive plates (9) and arranged on the stator body and current collectors (8) connected to the coil windings of the rotor electromagnets. According to said invention, the coil windings of the adjacent rotor electromagnets are connected to each other pairwisely in series aiding and connected in series opposition to the coil windings of the pair of diametrically opposite electromagnets. In addition, capacitors are connected to the ends of the winding, which are connected to the collectors, in such a way that resonance circuits are formed, the number (n) of the stator permanent magnets and the number (m) of said resonance circuits are defined according to a relation n=10+4k, wherein k=0, 1, 2, 3, , the number of the collector plates of the distribution collector is equal to the number of the stator permanent magnets, the central lines of the dielectric gaps (10) of the distribution collector are oriented along the central lines of said magnets. Said invention increases the torque of the electric motor.
