ROTATING ELECTRICAL MACHINE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240136874 titled 'ROTATING ELECTRICAL MACHINE
Simplified Explanation
The rotating electrical machine described in the abstract includes a rotor with a rotor core and a combination of magnetic poles made up of permanent magnets and dummy poles. These poles are arranged alternately in both axial and circumferential directions, with non-magnetic holes between adjacent magnet and dummy poles in the axial direction. The dimensions of the poles and holes are such that the machine satisfies specific length relationships.
