Abstract

Un motor electrico tiene un rotor y un estator. El rotor se soporta por un cojinete sinterizado asociado con el estator. El cojinete 10 coopera con un empalme 18 en el rotor para formar una interconexion de empuje. El empalme tiene una superficie 19 plana con un diametro A exterior. El cojinete 10 tiene una superficie radialmente exterior cilindrica, un orificio 13 central con un diametro B y dos caras 12 de extremo. Una cara de extremo tiene una superficie 16 de empuje axialmente inclinada que tiene un borde interior con un diametro C y un borde exterior con un diametro D en donde: C < A < D y B <= C <= 1.5B.
