2.5 - 75 kVA | NC-RNC series
Nuova Saccardo Motori
These electrical machines are expressly designed and manufactured for military, aeronautics and other purposes where high performances and reliability are required. They are constructed in the singleblock 2 ball bearings version and on coaxial 4 ball bearings version with couplement joint and basement.
They are available in both version: synchronous and asynchronous with 1% slip or 2% slip.
On request the electric drive panel is supplied.
GENERAL TECHNICAL DESCRIPTION
Asynchronous motor with cage or selfstarted syncronous motor by means special rectifier bridge.
Selfregulated 400 Hz alternator brushless type
