Nice rebuild - incidentally, in this context "charbon" is "brush" and "collecteur" is "commutator"

In theory with certain motors yes, the excitation coils must be fed in a different way in order to produce the maximum of magnetism during the welding not too much between the periods of welding in order to avoid overvoltages.

Do not know your generator, but in principle you have to put a rehostat in the excitation circuit. A variac is for AC.

Très belle vidéo et très détaillée. Mais je suis un peu étonné, c’est que dans toutes les procédures, même avec le moteur tournant, qui est donc alimenté ; la personne n’a pas du tout utilisé de gant. Je m’abonne à cette chaine, car cela est vraiment intéressant à connaitre. On s’aperçoit qu’il existe énormément d’appareils et outils de travail que l’on voit tous les jours, sans se poser la question de savoir comment cela est fabriquer, monté ou réparé.

Pour ce qui de la question de port de gants, tout travail manuel que se soit comporte des risques de blessures, pour bien des tâches représentées ici le risque est bien moindre que de couper une carotte dans sa cuisine avec un couteau plus ou moins bien affuté ! Pour les risques électriques le travail directement sur des parties sous-tension impose le port de gant spécifique dans tout les cas. Sur un machine ou des appareils où la source de l'alimentation est déconnectable physiquement (Fiche-prise dans notre cas), l'opérateur est seul responsable des risques potentiels qu'il prend lors des préparatifs. Le fait d'évoluer à proximité d'un appareil électrique en service n'impose pas le port des gants. Trop de sécurité nuit à la sécurité, les gens trop déresponsabilisés ne font plus attention à ce qu'il font !

140 Fraken per Stunde? Klingt nach viel, ist es aber, meiner Meinung nach, nicht. Alleine bei der Präzsion die hier beim drehen des Kommutator angesetzt wird, kann man eine Stange mehr verlangen. Wohl gemerkt, der Motor wird schon etliche jahre in Betrieb gewesen sein und es ist für den Betrieb billiger, diesen neu aufbauen zu lassen als einen gleichwertigen, neueren Motor zu beschaffen. Das sagt einiges über die Langlebigkeit alter Technik aus. Das Einzige was mich etwas gestörrt hat waren die offen zugänglichen Kontakte während der tests, aber das auch nur, weil ich michs elber kenne und irgendwie dagegen gekommen wäre.

It is odd that the 6th brush holder is not used. It would reduce amperage per brush, and distribute brush / segment wear more evenly. They're not conserving anything by not having the 6th brush installed. At 6:10 he shaves off the unused brush surface thickness to the same depth as everything else.

@YvesMamin

3 жыл бұрын

This is a false belief. A brush behaves better and there is less wear and tear when it is moderately hot. if there is too much brush, the amperes per square minimeter are too low and seizure or stains on the collector may appear. When there are quality problems on the collector surface, the first attempt to correct the problem is to reduce the number of brush or their section. As a general rule one should not have less than 2 amps per square minimeter, this rule is not absolute the environmental conditions can also have an influence.

@YCbCr

That's an interesting topic! I wonder how it is managed in locomotives' DC traction motors where the brushes should work just as well at max (rated) current while starting-accelerating, and at much lower amperage at speed - anywhere from -2000 to 2000 RPM. A common loc around here for example: 1400 V, 1050 A (starting 1700), series excitation (with shunts), sensitive beast prone to flashover - and two pf these to double the fun :)

Quels sont les domaines d'utilisation d'un moteur à courant continu ??

@YvesMamin

Жыл бұрын

Ce type de moteur était couramment utilisé partout ou il y avait besoin de pouvoir facilement modifier la vitesse de rotation (ventilation, pompage...) ou de gros couple au démarrage (Traction ferroviaire). Il sont remplacé aujourd'hui par des moteurs triphasés avec des variateurs de fréquence bien meilleur marché à entretenir. Notons que dans le cadre de mon activité professionnelle on voit réapparaitre bien quelques moteurs de ce type depuis quelques mois à cause (ou grâce..) à la pénurie de composant électroniques pour les variateurs de fréquence.

Looks very expensive and time-consuming. No wonder they're replacing these with VFDs and induction motors.

For new installations yes ! For the perfectly functional old no! These engines are 30 years old and operate without problems. We also work with VFDs, their lifespan does not exceed a few years and there are always compatibility problems when they are changed. It is a waste of raw materials ! The VFD generates other problems just as expensive as the overhaul of these old engines ( kzread.info/dash/bejne/fqeAz9l-mafKhLQ.html )

La remarque à déjà été faite ici il y a une année environ (en anglais, voir ci-dessous Jojo Villanueva). L'eau de cette place de lavage est récoltée dans deux fosses de séparation des graisses et stockage des eaux usées, le contenu de ces fosse est vidé et traité comme déchets spéciaux par une STEP. Vous noterez qu'aucun produit de nettoyage n'est utilisé, seulement de l'eau chaude ceci afin d'éviter la dissolution des corps gras dans l'eau. La législation Suisse sur la protection des eaux est très stricte et des infractions dans ce domaine coutent une petite fortune !
