Abstract

Un alojamiento para un anillo de tierra que incluye una cubierta de alojamiento configurada para aceptar un anillo de tierra y mantener el anillo de tierra en una posición predeterminada alrededor de un eje que está conectado eléctricamente a un eje de accionamiento de un motor eléctrico. El anillo de tierra tiene una primera abertura para el eje de accionamiento y la cubierta del alojamiento tiene una segunda abertura para el eje de accionamiento. El alojamiento incluye un acoplamiento configurado para mantener la cubierta del alojamiento alrededor del eje para disipar una carga eléctrica y para formar una cavidad que contiene el anillo de tierra e incluye un espacio predeterminado entre un perímetro de la segunda abertura del alojamiento y una superficie del eje de accionamiento.
