Title:
FLAT BRUSHLESS MOTOR
Document Type and Number:
Japanese Patent JP3255131
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To arrange terminals with a high density near adjoining electronic components on the board of an apparatus, and to permit high-efficiency mounting by a surface mounting system, by providing an outer shell composed of a bottom surface, side surfaces, and an upper surface, and fitting a plurality of terminals having a function of joining mechanically and electrically to the board of the apparatus on the bottom surface side.
SOLUTION: A stator 1, a printed board 2, a bearing device 3, a rotor 4, and a cover 5 are provided, and the cover 5 mainly forms the upper surface and the side surfaces of a motor, and the printed board 2 forms parts of the side surfaces of the motor and a bottom surface. The stator 1 is formed by covering the surfaces of the stator core 6 with insulating films, and winding coils 7 after that. Besides, a plurality of lands 2a, 2e are provided on the bottom surface of the printed board 2, and a plurality of lands 2b are provided also on a stator fitting surface. A metal surface 2c for soldering the projection 5b of the cover 5 is formed on the peripheral side surface. The lands 2a, 2e have terminal construction suitable for soldering by a surface mounting system.
