Title:
DOUBLE AIR GAP-TYPE SURFACE PERMANENT MAGNET SYNCHRONOUS MOTOR PROVIDED WITH NON-MAGNETIC SHIELDING MEMBER
Document Type and Number:
WIPO Patent Application WO/2022/114388
Kind Code:
A1
Abstract:
The present invention relates to a double air gap-type surface permanent magnet synchronous motor provided with a non-magnetic shielding member. More specifically, the present invention has a double structure of rotors and stators, one pair each, for improved torque, and for high efficiency and high output power density satisfying IEC international efficiency rating of IE5, and is provided with a non-magnetic shielding member to prevent magnetic flux of the two permanent magnets from offsetting each other.
