Title:
MOTOR OR GENERATOR CAPABLE OF CHANGING SPEED AND CHANGING EFFICIENCY RANGE ACCORDING THERETO
Document Type and Number:
WIPO Patent Application WO/2023/054953
Kind Code:
A1
Abstract:
The present invention provides a motor or a generator in which the number of poles of winding is reduced and phases are converted in the forward direction by means of a neural point changeover switch and a phase changeover switch, and thus maximum efficiency can change according to changes in speed, or impedance and counter electromotive force are changed by means of series/parallel and start-delta connections of windings, and thus speed can change and maximum efficiency can change according thereto.
