Moulded commutators technologies :
We realised 3 technologies of commutators, to give the bestest solution at your needs.
Copper segments :
electrolytic copper A1 or E-Cu and according to customer requirements with
silver 0,03% , 0,1% or other.
According to the
technology, we use phenolic, epoxy or polyester compound, all are glass fibre
reinforced. These are all Class “H” compounds and have very high dielectric
traction quality ( organic or inorganic)
steel or laminar gray iron (FGL 250-300) or spheroidal (nodular) (FGS 400-7
or FGS 500-7). The hubs can be provided with cooling surfaces as well as
front and rear flanges of different forms. They can be finished to customer’s
specifications complete with keyways, specific bore tolerances, threaded
holes, recess, and all other forms.
The riser is
usually a large part of the copper segment, slotted or unslotted. It can also
be a fabricated riser with flag/terminals welded on (Tin soldered or Electron
beam welded on).
