Abstract

Dispositif d'isolement de l'enroulement d'excitation d'un moteur synchrone dont le rotor consiste en un aimant permanent. Il comprend un manchon de matière plastique qui est emprisonné entre des plaques opposées du stator et aussi entre les joues d'un bobineau sur lequel l'enroulement d'excitation est placé, afin d'isoler électriquement le fil de l'enroulement des autres éléments du moteur. Application aux moteurs synchrones équipant des dispositifs de mesure du temps, tels qu'horloges ou minuteries.Device for isolating the excitation winding of a synchronous motor whose rotor consists of a permanent magnet. It comprises a plastic sleeve which is trapped between opposing plates of the stator and also between the cheeks of a coil on which the excitation winding is placed, in order to electrically isolate the wire of the winding from the other elements. of the motor. Application to synchronous motors fitted to time measuring devices, such as clocks or timers.
