Constant Force Spring
Constant Force Spring
Constant force spring for brush holder are generally made of stainless steel spring steel. Apply constant pressure to the carbon brush in the constant force brush holder to ensure that the carbon brush is in close contact with the torus to make it work stably. The constant force spring is relatively uneven in the force value avoided by the tensile and compression springs, so that the carbon brush performance can be fully utilized.SINO HUAYUAN can offer a complete set of constant force springs and brush holder designs.
