Abstract

UN RESISTOR (8) PCT LAMINADO DE METAL ESTA SITUADO EN LA TAPA DEL EXTREMO (2) DE UN MOTOR ELECTRICO. LAS SUPERFICIES TRANSVERSALES OPUESTAS (9 Y 10) DEL RESISTOR PTC (8) ESTAN SUJETAS POR MIEMBROS ELECTRICAMENTE CONDUCTORES (11 Y 12) QUE ESTAN CONECTADOS RESPECTIVAMENTE A UNA DE LAS ESCOBILLAS (5) Y A UNO DE LOS TERMINALES DEL MOTOR (6) DE TAL FORMA QUE EL SUMINISTRO DE ELECTRICIDAD SE INTERRUMPE CUANDO EL RESISTOR PTC (8) SE CALIENTA POR ENCIMA DE UNA TEMPERATURA PREDETERMINADA COMO RESULTADO DE UN FLUJO DE CORRIENTE EXCESIVO. EL RESISTOR PCT (8) ESTA SUJETO EN CONTRA DEL MOVIMIENTO PERPENDICULAR A LAS SUPERFICIES TRANSVERSALES (9 Y 19), EN AL MENOS UNA DIRECCION, Y POR LO TANTO DE FORMA INDEPENDIENTE DE AL MENOS UNO DE LOS MIEMBROS DE CONTACTO (11 Y 12) DE TAL MANERA QUE, COMO MAXIMO, SOLAMENTE UNO DE LOS MIEMBROS DE CONTACTO (11 Y 12) ES NECESARIO PARA SUJETAR EL RESISTOR PTC (8). AMBOS MIEMBROS DE CONTACTO (11 Y 12) PUEDEN ADEMAS CONSTITUIR EL PUNTO DE CONTACTO CON EL RESISTOR PTC (8) YELLO MEJORA EL FUNCIONAMIENTO INHIBIENDO LA CONDUCCION DE CALOR HACIA O DESDE EL RESISTOR PTC (8)
