Chiaravalli – Technical Data-sheet – Cast Iron Motors

Role
Cast-iron motors where stiffness and vibration damping are needed in severe duty.

Parameters

• Efficiency class and duty (S1 baseline) with ambient/altitude derating.
• IP rating, insulation class, bearing types and regreasing intervals.
• IEC mountings (B3/B5/B14) and terminal box orientation.

Checks

• Confirm supply (voltage/frequency) and start method vs. protection devices.
• Assess load inertia and start frequency; verify shaft height/frame.
• Select seals for dust/humidity/chemicals; log baseline vibration.
