Abstract:
Provided is a flat type vibrating motor capable of reducing a consumed current of the motor while maintaining torque of the motor, lengthening even more an operating time of an apparatus such as a mobile communication apparatus in which the flat type vibrating motor is mounted, and shortening a charging period. At least one auxiliary coil separated at a predetermined mechanical degree with respect to a center of the primary coil mounted on the substrate, and series-connected to the primary coil is provided, so that a current flowing through the coil is reduced and torque equivalent to or greater than that of a related art motor can be obtained. Accordingly, an amount of a consumed current of the motor is reduced.
