The Influence Of The High Temperature Of The Carbon Brush On The Motor Causes The Temperature Rise Of The Carbon Brush Of The Motor To Be Too High Or Abnormal Wear

The influence of the high temperature of the carbon brush on the motor causes the temperature rise of the carbon brush of the motor to be too high or abnormal wear, so you must pay attention to it when using it. Compared with steel collector rings, copper collector rings such as bronze castings have good sliding characteristics, so they are widely used, but when they contain a large amount of lead with low melting point, they are deleaded due to the heating of the energizing point, which is easy to cause wear of the collector ring or abnormal wear of brushes. In the coordination between the collector ring and the brush, when the abrasiveness of the carbon brush is too strong and the material of the collector ring is too soft, the stepped wear equivalent to the width of the brush often occurs on the collector ring. In particular, fully enclosed motors with high temperature and low humidity are more likely to cause excessive wear of brushes or collector rings.
