Samsung patents motor design with bent metal bridges in rotor
Samsung has been granted a patent for a specific type of electric motor. The design features a rotor core made of layered metal parts connected by bridge sections that bend back toward the main structure.
In the filing’s own words
A motor may include a shaft, a stator and a rotor. The rotor may include a plurality of magnets, a casing and a rotor core. The rotor core may include a plurality of first core layers and a plurality of second core layers. The first core layer may include a base part through which the shaft passes, a plurality of core parts spaced apart from each other along a circumferential direction of the base part, and a plurality of bridge parts configured so that each of the plurality of bridge parts extends from a corresponding core part of the plurality of core parts toward the base part, and is bent toward the corresponding core part.
What exactly they claim (claim 1)
1. A motor comprising: a shaft; a stator; and a rotor, wherein the rotor includes: a plurality of magnets; a casing; and a rotor core, wherein the rotor core includes a plurality of first core layers and a plurality of second core layers, wherein the first core layer includes: a base part through which the shaft passes, a plurality of core parts spaced apart from each other along a circumferential direction of the base part, and a plurality of bridge parts configured so that each of the plurality of bridge parts extends from a corresponding core part of the plurality of core parts toward the base part, and is bent toward the corresponding core part.
