Title:
PERMANENT MAGNET TYPE THREE-PHASE MOTOR
Document Type and Number:
Japanese Patent JPH10234167
Kind Code:
A
Abstract:

To increase the degrees of freedom in design by reversing the winding direction of a winding to be wound around a ties, where a phase difference is generated in a specific in-phase induced voltage with reference to an arbitrary ties of each phase, when all windings are wound in the same direction, thereby increasing the torque and thus the output.

When all windings 3 are wound in the same direction, winding direction of the winding 3 to be wound around a ties 4 in which a phase difference represented by 90<θ<270, where θ=a-360.INT(a/360) and a=360.3.2∼n.Tp/m is generated in an in-phase induced voltage with reference to an arbitrary ties 4 of each phase is reversed. More specifically, a reference ties is set for each phase and winding direction is reversed, as compared with the winding 3 for a ties 4 generating an induced voltage having a phase of electric angle 90°-270° with respect to the reference ties. According to the structure, the torque and thereby the output is increased, resulting in a increase in the degrees of freedom of a design.
