Rating plate
The rating plate shows the identification data and the most important technical data. The data
on the rating plate and the contractual agreements define the limits of proper usage.
Rotor
The rotor is designed as a squirrel-cage rotor. The number and design of the shaft extensions
are shown and described in the technical data.
Cooling
The cooling system is designed as a closed, internal cooling circuit. The mounted cooler is an
air-to-water heat exchanger with a pipe system. The heat lost from the machine is dissipated
via the surface of the cooling pipes to the cooling liquid flowing in the pipes. External fans
facilitate the circulation of the cooling air in the primary circuit.
External fan
The machine is fitted with an external fan. For IC 666, there are two external fans. The electrical
connection data are stamped on the rating plate of the external fan.
Supplementary devices
Temperature sensors are integrated in the stator winding to monitor the winding temperature.
Various supplementary devices can be integrated or mounted, depending on the order. These
include, for example, anti-condensation heating to prevent condensation or temperature
sensors for monitoring bearings.
