Twice The Life

For series universal motors longer brushes mean longer life. Typically, brush length is limited by the effectiveness of the spring that holds it in place. AMETEK solved this problem with a curved brush that allows it to increase brush length on its Eternity Brush motors by as much as two thirds. The result is a life span that is two to three times that of traditional straight brush-design motors. In 12-amp applications, the curved Eternity Brush translates into an average of 1500 hours of service life. In lower amp motor applications, vacuum motors with Eternity Brushes have operated for 5000 to 8000 hours.
