In the manufacturing and processing of electric motors, ventilation channel steels need to be welded on rotor sheets. The ventilation channel steel is an important part of the heat dissipation structure of an electric motor. During operation of the electric motor, a large amount of heat is generated. The ventilation channel steel conducts heat to the channel steel through contact with the motor housing and dissipates the heat through the ventilation channel of the channel steel, thereby reducing the temperature of the electric motor. The components inside the electric motor, such as windings and bearings, are sensitive to temperature. Excessive temperature can cause damage to these components. The ventilation channel steel protects the internal components of the electric motor through heat dissipation, thereby prolonging the service life of the electric motor.
