ROTOR ASSEMBLY OF FLAT TYPE OSCILLATION MOTOR

摘要

PURPOSE: A rotor assembly of a flat type oscillation motor is provided to simplify a structure to be assembled, improve efficiency in manufacturing a rotor, enhancing an oscillation performance and making the motor being thinner. CONSTITUTION: An upper substrate(80) is a circular printed circuit board which enables a circuit to be printed on a surface. An insert hole(81) is formed on a rotary central part of the circular upper substrate(80). A commutator has a plurality of segments at uniform intervals. A plurality of coils(90) are arranged on an upper surface of the upper substrate(80) and correspond to each other based on the insert hole(81). The coils(90) are firmly bonded by an adhesive agent and soldered with a circuit terminal on the upper substrate side. The coils(90) are slightly eccentrically formed toward a side on the upper substrate(80). An eccentric unit is formed by integrally coupling a bearing part and a weight part.
