V-Type is a carbon brush holder designed to attain balanced spring pressure, current distribution and reduced carbon brush wear. We have achieved this by using a main spring for all the brushes in the same phase and ensuring the angle to the slip ring is always 90°. This allows for adjustment of the angle of the pressure fingers to compensate for the spring’s various properties and the carbon brush’s actual weight when the brush is worn down.
The V-Type carbon brush holder also has a pressure plate that distributes the pressure. It also eliminates conductors in the carbon brushes from coming into contact with the slip ring when the brushes are worn down.
A carbon brush is not homogenous but pressed with a specific density that results in small variations of brush wear. To solve this, the V-type is equipped with compensation springs for each individual carbon brush.
