Robust design
for highest reliability
Cylindrical outer core frame made of mechanically welded steel with raised legs IM1101 and steel shields. Its compact construction guarantees the grater rigidity and resistance of the generator against mechanical stresses.
Generator shields designed to withstand axial and radial mechanical stresses and high vibration values. The shields could include a SAE flange adaptor on demand.
Double bearing design equipped as standard with two ball bearings.
