摘要:
A slender-type cylindrical coreless motor for use in battery driven equipment in which power-consumption is low, high reliability is achieved, miniaturization and long-term battery driving of the equipment are realized. The slender-type cylindrical coreless motor includes: a pipe (2) with one end fixed to a frame (1); a cylindrical magnet (3) disposed around the outer surface of the pipe (2); and an inner bearing (7) for holding a fixed portion of a shaft (5) to a rotor assembly body (4). A second end portion of the pipe (2) has a length that does not permit protrusion thereof from an end surface (3b) of the magnet (3), and the inner bearing (7) is located at the end surface (3b) of the magnet (3) concentrically with the outer diameter of the magnet. Portions of the inner bearing (7) and the end surface facing each other are joined with solder material, and portions of the pipe (2) and the magnet (3) facing each other are joined with solder material.
