Abstract
Le détecteur d'usure de palier selon l'invention comprend trois bobines de détection 10, 12, 14 montées en étant décalées angulairement d'environ 120 degrés sur le stator 16 de l'appareil électrique dont on veut mesurer l'usure des paliers; lesdites bobines étant reliées en série pour donner une tension résultante qui indique le déplacement des axes 18 et 20 l'un par rapport à l'autre par suite de l'usure des paliers. Applications entre autres moteurs et générateurs électriques.
