Title:
ROTARY ELECTRIC MACHINE
Document Type and Number:
WIPO Patent Application WO/1993/008634
Kind Code:
A1
Abstract:
A rotary electric machine constructed on the basis of a new operational principle, which is operated by using a magnetic repulsive force as its driving force and can be utilized as a motor, etc. In the rotary electric machine, provided are a hollow cylindrical rotor, an outside stator provided concentrically on the outside of the rotor with an outside gap between them, and an inside stator provided concentrically on the inside of the rotor with an inside gap between them. To the outside stator, attached is an outside field system having a plurality of magnetic poles of like polarity at certain spaces along the inner circumference of the outside stator; to the inside stator, attached is an inside field system having a plurality of magnetic poles of the polarity opposite to that of the magnetic poles of the outside field system at certain spaces along the outer circumference of the inside stator. To the rotor, attached is an armature having a plurality of magnetic paired poles disposed at certain spaces along the outer circumference of the cylindrical rotor in such a way that one of each of the magnetic pole pairs appears in the outside gap and the other appears in the inside gap. Provided is a commutation mechanism for so exciting the armature of the rotor that the outside magnetic poles of the rotor are the same polarity as that of the magnetic poles of the inside stator. The commutation mechanism, further, so excites the rotating armature that the magnetic poles of the armature disappear just before the magnetic poles of the outside and inside stators and that they appear again just after the magnetic poles of the outside and inside stators and that they appear again just after the magnetic poles, of the stators during the rotation. Since such a rotary electric machine has a large output torque, it can be used, for example, as a source for generating the driving force of an electric vehicle.
