Abstract
A compressor motor and a method for magnetizing a rotor thereof are provided. The compressor motor includes a stator and a rotor configured to electromagnetically interact with the stator to be rotated, wherein the rotor includes a core, a plurality of magnets inserted into the core, and a cover configured to cover both end portions of the core and to be injection-molded so as to fill accommodation spaces that are formed between the core and the plurality of magnets.
Claims20
A compressor motor comprising:
- a stator;
- and
- a rotor to electromagnetically interact with the stator to be rotated,
- wherein the rotor includes:
- a core having upper and lower end portions and a plurality of insertion holes formed within the core between the upper and lower end portions of the core;
- a plurality of magnets respectively inserted into the plurality of insertion holes of the core to form accommodation spaces between the core and the inserted plurality of magnets;
- and
- at least one injection-molded cover injection-molded to the core that fills the accommodation spaces and covers both of the upper and lower end portions of the core.
