MICRO-MOTOR AND APPARATUS USING THE SAME MOTOR

摘要

A motor includes a cylindrical frame (1) made of ferromagnetic material, a pipe (2) fitted in and disposed within the frame concentrically, a sintered bearing (7) press-fitted into the pipe, a cylindrical magnet (4) fixed on an outer wall of the pipe at an inner wall of the magnet, and a cylindrical coil (5) facing the magnet via an annular space, where the frame and the pipe are welded at a fitted section therebetween. This structure allows the motor to withstand a strong enough shock. An apparatus (100) requiring a vibration motor (200) can employ this motor having a large vibrator, so that great vibrations are available for the apparatus. As a result, the apparatus-utilizing the great vibrations as various functions-is obtainable.
