Figure 2-2 Schematic representation of machine type 1GG6<br />
Ventilation and cooling<br />
Terminal boxes<br />
Fan unit<br />
The machines are open-circuit ventilated with degree of protection IP23. The<br />
separately driven fan (cooling method IC06), normally mounted on the non-drive<br />
end, forces the cooling air through the machine. Optimized cooling-air passages in<br />
the stator and in the rotor ensure good heat dissipation from all windings, the<br />
laminated rotor core and the commutator.<br />
The terminal box has terminals for main circuits, shunt circuits (excitation) and, if<br />
appropriate, auxiliary circuits. The terminal boxes conform to degree of protection<br />
IP55.<br />
The unscrewable entry plate is supplied as standard without holes drilled so that<br />
the design, number and size of the cable glands can be adapted to the chosen line<br />
conditions.<br />
If a separate terminal compartment is prescribed for certain auxiliary circuits, an<br />
additional auxiliary terminal box must be mounted on the side of the box frame.<br />
The <strong>DC</strong> machine has a built-on fan unit that provides for separately driven<br />
ventilation.<br />
