BRUSHLESS VIBRATION MOTOR

摘要

PURPOSE: A brushless vibration motor is provided to improve the efficiency of a process by connecting a coil assembly formed by injection-processing a coil yoke and a coil with a land unit of a circuit substrate through a reflow process. CONSTITUTION: A stator(110) includes a bracket(111), a circuit substrate(113), and a coil(114). The circuit substrate supplies external power to the coil. The coil is connected to a coil yoke(115) to be placed on the side of a magnet(133). An operating IC(120) is placed on the top of the circuit substrate to control a current delivered to the circuit substrate. A rotator(130) includes a bearing(131), a rotor yoke(132), a magnet, and a polymer(134).
