3.3.1
Machine design
Machines of this series are low-voltage three-phase induction drives with a cylindrical shaft
extension and keyway. They can be supplied as single-speed machines with different efficiency
classes or as pole changing machines for several speeds.
In the case of machines with feet (IM B3 type of construction), the feet are cast or bolted on.
It is possible to change over the bolted on mounting feet on the machine enclosure, for
example to change the terminal box position; only authorized retrofit partners may carry out
this work.

Cooling and ventilation
The machines of this series are three-phase induction machines with a closed primary (internal)
cooling circuit and an open secondary cooling circuit (surface cooling). The surface cooling
varies depending on the version.
