Abstract: Brushless motors for portable information equipment that can be simultaneously reflow-soldered to a substrate and efficiently and densely mounted thereon in such a way that the coupled portion between the motor and the substrate has a high impact resistance, thereby providing small and reliable portable information equipment having a high productivity.

Abstract: A brushless motor, comprising a rotor having a magnet, a coil for generating a magnetic field for drivingly rotating the rotor, and a power supply terminal for supplying a power to the coil from outside, wherein all electrical connection parts ranging from the power supply terminal to the end of the coil are connected to each other through welded parts.

Abstract: A motor includes a rotor, a stator facing to the rotor, a motor-base-assembly for journaling the rotor and holding the stator. The motor-base-assembly is made of resin and includes a motor-base having openings and terminals made of metal. These terminals are inserted into the openings to be mated with the motor-base, and lower faces of the terminals are exposed from the bottom of the motor-base. This structure allows the terminals to be mated with the motor-base without using an insert-molding method, and permits high productivity of the motor. This advantage appears conspicuously in such a small motor, among others, as can be directly re-flow soldered to a board of a device. The device employing this motor enjoys high productivity and reliability because the motor can be directly re-flow soldered to the board of device.

Abstract: A motor includes (a) a stator having a stator core wound with a coil, (b) a rotor having a magnet facing the stator core via an annular space and a yoke disposed on an outer wall of the magnet, and (c) an unbalancing weight disposed on an outer wall of the yoke. This structure allows the motor to be small in size, light in weight, thin, flat and to function as a vibrating motor producing maximum vibration at low power consumption. The motor thus contributes to realizing a portable device with a small size, a low weight, and which is operable for many hours.

Abstract: A motor includes a motor-base-holder which comprises (a) a base, (b) a bearing supporter vertically protruded from the base for supporting a bearing, (c) a stator supporter concentric with the bearing supporter for being mounted with a stator, (d) a motor base having terminals made of a metal plate and insert-molded around the bearing supporter, and (e) a frame made of the same metal as the terminals and linked to fringe of the motor base. This structure solves difficulties of mini-motors such as difficulties of handling the motor, difficulties of mating those elements each other, and time-consuming bonding action. A method of assembling the same motor achieves high productivity.

Abstract: In a motor mounting mechanism, a cylindrical motor includes a frame (6) serving as a stator and an electric power supply terminal (2) attached to a bottom surface of a bracket (1). When the motor is mounted to a motor attachment device, a first external electrode (10) is mechanically and electrically connected to a cylindrical side surface of the frame (6) while a second external electrode (11) is mechanically and electrically connected to the power supply terminal (2). The first and second external electrodes are both located outside the motor, and thus, the process of providing lead wires for connecting the external electrodes to the printed board can be omitted, allowing the total size of the motor mounting mechanism to be reduced.

Abstract: A motor includes a stator core having a plurality of projected poles, a stator coil wound around an insulating portion of the stator core, a printed circuit board for supplying electricity to the stator coil, and a holder having a hollow projection and fixed to the stator core. The projection of the holder is inserted and fixed in a hole formed in the printed circuit board and is used for positioning and fixing the stator core. A portion of the projection of the holder has a hole. A terminal pin is fixed in the hole of the projection of the holder and has a step portion around which the stator coil is. The step portion is fixed to a solder land of the printed circuit board to be wired to the stator coil so as to make the terminal pin and the land electrically conductive.
