Title (EN) SYNCHRONOUS ELECTRIC MOTOR WITH MAGNETIZED ROTOR AND METHOD FOR FABRICATING SAID MOTOR
(FR) MOTEUR ELECTRIQUE SYNCHRONE A ROTOR AIMANTE ET PROCEDE DE FABRICATION DE CE MOTEUR
Abstract:
(EN) The disclosed motor comprises at least one magnetized disc (407) rotatingly mounted in the air gap of a stator assembly (416) comprising two pole piece assemblies, which assemblies are axially displaceable with respect to each other during the assembly operation. Spacer elements (such as 429) are placed between the faces of the magnetized disc and the respective pole pieces, before fixing the disc (407) on a support part (406). The support parts (406, 426) of the disc are provided with openings in order to remove the spacer elements after assembly of the motor.
(FR) Le présent moteur comprend au moins un disque aimanté (407) monté de façon rotative dans l'entrefer d'un ensemble de stator (416) comportant deux ensembles de parties polaires axialement déplaçables l'un par rapport à l'autre lors de l'assemblage. Des pièces d'espacement (telles que 429) sont placées entre les faces du disque aimanté et les parties polaires respectives, avant la fixation du disque (407) sur une partie de support (406). Les parties de support du disque (406, 426) comportent des ouvertures permettant l'enlèvement des pièces d'espacement après l'assemblage du moteur.
