Title:
DYNAMO ELECTRIC MACHINE
Document Type and Number:
WIPO Patent Application WO/2019/026725
Kind Code:
A1
Abstract:
Provided is a dynamo electric machine with which the generation of a counter electromotive force is inhibited, whereby high rotation can be achieved without applying a high voltage, and the reliability of a rotor can be maintained even when high rotation is continued for a long period. A motor 14, provided with: rotors 200 in which a plurality of permanent magnets 202 are disposed along a rotation circumference R1, the magnetic poles of the permanent magnets 202 facing directions along a rotation axis L1; and stators 300 in which a plurality of windings are disposed along the rotation circumference R1 in the directions in which the magnetic poles of the permanent magnets 202 face. A stator 300 is formed in a direction in which, when a rotor 200 faces end parts of the first winding 301 through fourth winding 304, the magnetic path from an end part of the stator 300 into the stator 300 intersects the direction of the main magnetic flux from the rotor 200. In the plurality of stators 300a, 300b provided along the rotation axis L1 of the rotors 200, the positions of gaps between the windings are shifted along the rotation circumference direction. The motor 14 can also be made to function as a power generator.
