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.
