TWO-PHASE FLAT-TYPE VIBRATION MOTOR

摘要

PURPOSE: A two-phase flat-type vibration motor is provided to extend the driving torque by increasing the number of winding and flux linkage, to produce motors with ease, and to secure stable driving by eliminating death point and disrupted section. CONSTITUTION: A two-phase flat-type vibration motor includes following steps. The number of stator magnate(20) equipped on a lower base panel is at least two. An amateur coil(50) connected to an upper base panel(40) has pi/2 phase difference of electrical angle from the upper base panel(40). A pair of brushes(30) are disparted from each other with pi electrical angle as well as connected to at least one of the segments(71).
