Abstract
According to a preferred embodiment of the present invention, in a structure in which a permanent magnet is embedded radially outwardly from a rotor portion, a pair of permanent magnets is embedded in a V-letter shape and a slit in a longitudinal direction is radially formed between the pair of permanent magnets. According to the preferred embodiment of the present invention, it is possible to implement relatively higher torque performance while minimizing the number of permanent magnets embedded in an interior permanent synchronous machine (IPMSM).
Claims11
A rotor assembly, comprising:
- a rotor portion provided with an embedded hole in which a rotating shaft is embedded;
- and
- a first magnet and a second magnet embedded into a first embedded hole and a second embedded hole that are formed at a cross section axially vertical to the shaft of the rotor portion radially outwardly from the rotor portion and formed so that a width of a spaced space increases radially outwardly from the rotor portion from a rotating central shaft of the rotor portion,
- wherein a slit is formed between the first magnet and the second magnet.
A rotor assembly, comprising:
- a rotor portion provided with an embedded hole into which a rotating shaft is embedded and including a first magnet and a second magnet embedded into a first embedded hole and a second embedded hole formed at a cross section axially vertical to the shaft so that a width of a spaced space increases radially outwardly from the rotor portion 10 based on a rotating central shaft;
- and
- a stator portion including at least one stator salient pole formed to correspond to the first magnet and the second magnet of the rotor portion and a stator yoke accommodating the rotor portion,
- wherein a slit is formed between the first magnet and the second magnet.
