Title:
ELECTRIC MOTOR AND ELECTRICAL APPARATUS COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2016/042730
Kind Code:
A1
Abstract:
The electric motor (100) of the present invention comprises a stator (40), a rotor (10), and a pair of bearings (30). The stator (40) has a stator core (41) formed annularly. The rotor (10) is located on the inner circumference side of the stator core (41), and has a shaft (12), a rotor core (11) and bond magnets (14). The bond magnets (14) are loaded into magnetic holes (13). The bond magnets (14) are formed with a high density portion (14b) that has a high density, and a low density portion (14c) that has a density lower than the high density portion (14b). In the electric motor (100), the center location (11b) of the rotor core (11) is on the side where the high density portion (14b) exists with respect to the center location (41b) of the stator core (41) in the direction of the shaft center (12a) of the shaft (12).
