CA 2174152

Apparatus may be inserted in the casing of a d.c. motor or a d.c. generator for measuring not only the magnetic fields prevailing in the machine but developing other useful information. The magnetic fields between the field poles and the armature, and also the armature/mmf fields aligned with the brushes may be measured. The measurements of the fields permits a complete plot of the fields in the machine and also permits a test to be performed to see if the brushes are at their optimum positions. If a brush is not at its optimum position, the brush may be shifted back and forth until the maximum mmf, due to the current through the armature is aligned midway between the leading and trailing ends of the brush area coverage on the commutator.

L'invention est un appareil qui peut être inséré dans le boîtier d'un moteur à courant continu ou d'une génératrice de courant continu pour mesurer non seulement les champs magnétiques internes, mais pour fournir également d'autres informations utiles. Les champs magnétiques créés entre les pièces polaires et l'armature, et également les champs alignés avec les balais, peuvent être mesurés. La mesure des champs permet de tracer le graphique de leur distribution dans la machine et d'effectuer un test visant à déterminer si les balais sont positionnés de façon optimale. Quand un balai n'est pas à sa position optimale, il peut effectuer un mouvement de va-et-vient jusqu'à ce que la force magnétomotrice maximale soit atteinte du fait que le courant dans l'armature se trouve à mi-chemin entre les extrémités de la zone couverte par le balai sur le commutateur.
