Machine design

Machines of this series are low-voltage three-phase asynchronous drives with a cylindrical
shaft end and featherkey way. 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 the feet bolted on the housing of the machine, e.g. to change the
position of the terminal box; however, only have this performed by an authorized retrofit
partner.
With the appropriate post working, ensure that the feet mounting surfaces are again on one
plane and parallel to the machine shaft, and shim when required. Professionally touch up
damaged painted surfaces.
