Title:
IRON CORE AND MAGNETIC CIRCUIT MULTIPLEXING REDUNDANT POWER DRIVING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/166229
Kind Code:
A1
Abstract:
An iron core and magnetic circuit multiplexing redundant power driving system. A magnetic circuit multiplexed iron core of an iron core and magnetic circuit multiplexing electric motor can serve as a magnetic circuit multiplexing channel of an electromagnetic field, so that a plurality of converters are connected to a plurality of sets of windings of one iron core and magnetic circuit multiplexing electric motor, and drive the iron core and magnetic circuit multiplexing electric motor together; thus, the power of the electric motor is not limited by the power of a single converter, the requirement of the driving system for an ultra-high power is met, and a plurality of driving branches meet the redundant requirement of the driving system. The system comprises: an iron core and magnetic circuit multiplexing electric motor, at least two converters and at least two sets of power supplies, wherein the iron core and magnetic circuit multiplexing electric motor comprises at least two sets of electric motor windings and a magnetic circuit multiplexed iron core; at least two sets of power supplies, at least two converters and at least two sets of electric motor windings form at least two driving branches; and the at least two driving branches provide electromagnetic fields, and the magnetic circuit multiplexed iron core serves as a magnetic circuit multiplexing channel of each electromagnetic field.
