Title
(EN) STRUCTURE OF MOTOR HAVING BUILT-IN ELECTROMAGNETIC BRAKE
(FR) STRUCTURE DE MOTEUR A FREIN ELECTROMAGNETIQUE INTEGRE
Abstract
(EN)
In order to provide an electromagnetic brake (24, 26, 27, 30) in a motor, a brake core (30) must be correctly positioned with respect to the output shaft (10) of the motor. So far, therefore, the bottom surface (18A) of the core housing (18) to which the brake core (20) is secured and the bottom surface (20A) of the brake core (30) have to be machined highly precisely, resulting in an increase in the cost and making it difficult to decrease the size. According to the invention, the brake core (30) and the core housing (28) are formed integrally as one piece by injection-molding plastic material to decrease after-treatments. Thus a compact motor having a built-in electromagnetic brake can be provided.
(FR)
Dans le but de ménager un frein électromagnétique (24, 26, 27, 30) dans un moteur, une partie centrale de frein (30) doit être correctement positionnée par rapport à l'arbre de sortie (10) du moteur. Par conséquent, la surface de base (18A) du carter (18) de la partie centrale auquel est fixée ladite partie centrale (20), et la surface de base (20A) de la partie centrale de frein (30) doivent être usinées avec une extrême précision, ce qui entraîne un accroissement du coût et ne facilite pas la réduction dimensionnelle. La partie centrale de frein (30) et son carter (28) sont moulés d'une pièce par injection de matière plastique pour réduire les traitements ultérieurs. On obtient ainsi un moteur compact possédant un frein électromagnétique intégré.
