摘要： A bracket assembly of a universal motor comprises: a bracket composed of a base portion formed as a certain shape and coupled to a motor stator, a plurality of supporting portions extendingly formed at the base portion with a certain length, a bearing mounting portion extendingly formed at an end of the supporting portions with a certain shape and for inserting a bearing thereto, a plurality of holder portions extendingly formed at the base portion with a certain shape and having a heat emission insertion hole therein for inserting a brush and emitting heat, and a plurality of spring mounting portions; brushes respectively inserted into the bracket holder portions; and springs respectively coupled to the spring mounting portions of the bracket, for elastically supporting the brush. In the bracket assembly of a universal motor, the number of components constituting the motor is reduced thereby to greatly reduce the fabrication cost. Also, the number of assembly processes is reduced thereby to enhance assembly productivity.
