Page: 29 / 188

Rotors
The rotor assembly is pressed onto the shaft together with the cage winding. The drive end of
the shaft usually has a cylindrical shaft end. Dependent on the design, a second shaft end
may be located at the non-drive end.
Drive
The motor speed is controlled using a converter. It has been optimized for operation with
SINAMICS low-voltage converters.
Other converters must comply with certain requirements: You can find more information in the
catalog or in the engineering documentation.
Line operation
The motor is supplied from the line system.
NOTICE
Destruction of the machine when operated directly from the line supply
The machine will be destroyed if it is directly connected to the line supply. Only operate the
machine using a converter.
NOTICE
Machine damage for operation on the converter
If you connect the machine to a converter, the machine can be damaged. Operate the
machine only on the electrical supply system.
Cooling
The cooling system is designed as a closed, internal cooling circuit. The heat lost from the
machine is dissipated partially via heat conduction and partially via the cooling air at the cooling
water flowing through the cooling pipes. A shaft-mounted fan ensures circulation of the cooling
air.
Degree of protection
The machine is available with degree of protection IP55.
