  • Brake motors are a particularly important application of the electric machine system according to the invention. These are units from a motor and a safety brake, which is usually constructed as a disc brake. The hub of the brake disc is connected to the shaft of the motor and rotates with it.
  • the brake disk which is provided with a braking surface on one or both sides, is pushed by an armature disk which can only be moved axially by spring force against a stationary brake bearing plate which is firmly connected to the motor.

Le bout (14) de l'arbre (6), qui déborde du palier (11) situé du côté borgne (2), comporte, afin de préparer un assemblage par liaison de forme (5), un manchon d'entraînement (7) enfilable sur l'extrémité côté borgne de l'arbre (6). Afin d'assurer un assemblage par liaison de forme (16), solidaire en rotation, l'intérieur de ce manchon d'entraînement (7) est réalisé de manière à correspondre à la forme du bout (14) de l'arbre (6) et l'extérieur dudit manchon est solidaire en rotation du moyeu (8) de l'accessoire de charge élevée (1b). Ce dernier peut être, comme décrit ici, un frein de sécurité. Il peut aussi être une roue libre à antiretour. L'accessoire de faible charge (1c) est réalisé ici sous forme de ventilateur, mais peut être également un générateur tachymétrique ou un générateur d'impulsions.
