Abstract

"ESTATOR CONFIGURADO PARA UTILIZAçãO EM UM MOTOR, E, PROCESSO DE FABRICAçãO DE UM ESTATOR DE PAREDE ESPESSA". São divulgados um estator (320) de parede espessa do tipo Moineau e processo de fabricação. O perfil externo (355) do estator segue o perfil helicoidal interno (353) do estator. A aplicação de uma camada de elastómero (330) ao perfil interno do estator resulta em uma espessura constante da camada do elastómero e proximidade para as paredes do estator. Isto melhora a durabilidade do motor, por causa da baixa geração de calor e da melhor dissipação de calor. As paredes do estator também suportam a camada de elastómero. Além disso, as paredes espessas do estator preferido eliminam a necessidade de uma tubulação de perfuração adicional ou de outro suporte colocado adjacente ao estator. Assim, são eliminados os custos de tubulação adicional e as dificuldades de se colocar o estator dentro do tubo de perfuração ou da estrutura da cadeia de perfuração. Além disso, a resistência mais elevada do aço da parede espessa, quando em contraste com a contraparte de parede fina, permite uma maior queda de pressão de operação para um dado comprimento de estator, resultando em uma maior potência. Ainda mais, o perfil externo ondulado do estator dá uma aparência distinta à tubulação do estator.
