Abstract

According to the embodiment, an interior permanent magnet rotor (30) comprises: a rotor shaft; a rotor core (10) mounted to an outer circumference of the rotor shaft; and permanent magnets (3) located inside the rotor core (10) and arranged to form one pair or a plurality of pairs with each other in a circumferential direction in each magnetic pole part. The rotor core (10) includes an inner core (12) mounted to the outer circumference of the rotor shaft, an outer core having a fan shape located in each of the magnetic pole parts, a filling member filled between the inner and outer cores, and a positioning member configured to maintain a relative position between the inner core and each of the outer cores. The inner core and the outer cores are formed so that the inner core and the outer cores engage each other via the filling member.
