Shaft
The shaft is manufactured of forged or rolled steel and
machined to exact specifications. The shaft ends can be
cylindrical, conical or flanged, or two shaft ends can be
provided (double end drive).
Rotor windings
The rotor windings are either made of preformed enameled
rectangular copper wire or flat copper. Proper supports
between adjacent windings are used to ensure stability up to
the rated overspeed. The rotor windings are made to match
the insulation class of the stator. This ensures outstanding
reliability and a long service life, even with asymmetric loads
or under exceptional conditions.
