The invention discloses a carbon brush for an industrial motor. The carbon brush for the industrial motor comprises a carbon brush body. Gaps are evenly formed in the side face of the carbon brush body which comprises a carbon brush seat and a carbon brush. The carbon brush seat and the carbon brush are integrally formed. Two strands of wires are led out from the carbon brush on two sides of the carbon brush seat. The middle of each of the strands of wires penetrates through a copper block. Four ways of channels are formed in the copper block in a separating mode. All strands of wires penetrate through corresponding channels and are combined and then are connected with a metal piece in a welded mode. The carbon brush for the industrial motor has the advantages that the two strands of wires are led out from the carbon brush on the two sides of the carbon brush seat, the middle of each strand of the wire penetrates through the four ways of the channels of the copper block, and therefore the middle of each wire is not prone to cracking due to vibration of the motor, the gaps are evenly formed in the side face of the carbon brush body, the carbon brush with the structure is clamped on a metal support and is not prone to dropping, and service life is long.
