Flat brushless motor

Abstract

The present invention relates to a miniature pancake brushless motor. It includes button-shaped base seat, enclosing cover, PCB printed circuit broad and IC control integrated circuit. On the base seat a supporting shaft is fixedly mounted, and on the supporting shaft a rotor component is cover-mounted, and the stator component is placed around the rotor component. The described PCB printed circuit board is cover-mounted on the supporting shaft and positioned over the rotor component and stator component and placed in the enclosing cover, and the described IC control integrated circuit is placed on the PCB printed circuit board.

Description

technical field [0001] The present invention relates to a micro motor, in particular, to a flat brushless motor for a cellular phone. Background technique [0002] The use of cellular phones has brought us mobile communications, and people cannot live without it. One of the components in cellular phones is the vibration motor as a standard feature, which is used to notify incoming calls or messages in quiet places. [0003] However, almost all of these motors are mechanically commutated vibrators. This type of vibration motor has a short life and generates electric sparks. Recently, this type of vibration motor has been applied to more functions due to the disadvantage of short life. However, there are obstacles in the development of mobile phones, because these mobile phones are expensive and cannot be discarded as quickly as before; on the other hand, for example, in some flammable environments, the electric sparks generated by mechanical commutators also have some side e...
