Commutators made in Steel
Group in steel, bolted or screwed, depending on the case.
Mechanical Test- Speed, temperature and duration of tests are defined depending on the case.
Other tests should be done depending on the desire of clients (specifications).
Electrical Tests- The all production is submitted to this control. 1500V 50Hz between strip and mass; 500V 50Hz between strips.
Different voltage tests can be eventually specified by the client. (Reinforced insulation (3000-4000 Vca 50Hz)
Materials- All the materials used must pass the severe quality control established by our research laboratories.
Mechanical Test- For each produced, we forecast a statistical sample of commutators submitted to the mechanical control defined by the clients.
