Abstract
A permanent magnet embedded motor includes: a stator, including a stator core and a coil for excitation, the stator core being formed in an annular shape by laminating a plurality of steel plates obtained by punching a rolled steel plate material; a rotor, arranged inside the stator and including a permanent magnet; and a housing, made of metal and including a fitting recess of a cylindrical shape centered on a predetermined axis for fitting the stator therein. The stator is shrink-fitted into the housing, with a rolling direction of the steel plate being oriented in an expansion direction in which an inner diameter of the fitting recess undergoes a large amount of change during heating of the housing.
