In addition, our generators come with a stator core pressing system that utilises bolts through the stator core. This way, we give you pressing force precisely where it is needed: in the core, not at the back of it.
Our stator windings are insulated with class F main insulation using mica-glass tapes - either as a preimpregnated system (Duritenax) or as a dry tape system with subsequent vacuum-pressure impregnation (VPI, Micadur).
A closed loop air ventilation circuit is provided as standard with our medium and large machines. In cases where high output is required or where the output per pole of a high speed machine is very high, we offer state-of-the-art cooling systems. These feature direct water cooling in the stator winding by means of stainless steel hollow strands and direct water cooling of the rotor winding.
