Abstract
The utility model discloses a coil winding on a power generator, which is arranged on a stator for generating magnetic field or a rotor for energy conversion. The coil windings are symmetrically arranged on the power generator. Each coil in the same phase winding is arranged under different pairs of magnetic poles. Teeth and grooves under each pair of magnetic poles shift in relatively large space, thus the composite electric potential in the winding is weak and relatively good electric potential sine waveform is obtained and simultaneously the resistance torque due to teeth, grooves effect is also reduced.
