Abstract

An over-load protector for the motor of cleaner features that the electric brush module of said motor is composed of brush fixing supporter, brush casing, brush, spring for making the brush in always contact with stator module, and the leaf spring terminal which is in contact between stator module and brush casing. When the current applied to stator module is higher than a predefined value, said leaf spring terminal can cut off the current path.

Description
