Title:
ELECTROMAGNETIC MOTOR
Document Type and Number:
WIPO Patent Application WO/2005/034307
Kind Code:
A1
Abstract:
It is possible to increase the efficiency and output without requiring a complicated manufacturing procedure or increase of the cost. An electromagnetic motor includes: a stator fixed to a rotary shaft; a u-phase coil winding unit, a v-phase coil winding unit, and a w-phase coil winding unit which units are arranged radially from the stator and have a phase difference between them; and a first power supply terminal, a second power supply terminal, and a third power supply terminal for supplying a predetermined power to the coil of the respective phases. The motor uses &Dgr -shaped line connection. At least a two-layered coil layer is formed in the coil winding unit of each phase u, v, w by repeating at least twice the coil winding sequence consisting of: the first power supply terminal → the u-phase coil winding unit → the second power supply terminal → the v-phase coil winding unit → the third power supply terminal → the w-phase coil winding unit.
