摘要
自从电动机出现就已经有了轴承电流的存在,最近几年来,这种电流所造成的破坏出现了上升的趋势。为了避免轴承的损坏,需要提供正确的接地,使得漂移电流返回变频器外壳而不是通过轴承。
While bearing current have been around since the advent of electric motors, the incidence of damage they cause has increased during the last few years To avoid damage occurring, it is essential to provide proper earthing paths and allow stray current to return to the inverter frame without passing through the bearing
