Electric Machines
Liebherr manufactures electric motors as compact and maintenance-free three-phase squirrel cage motors and permanent magnet machines. In addition to their robustness, they are also characterised by their high power density. The motors are primarily suited for use in variable speed drives with frequency converters. They also support highly dynamic applications such as quick lifting and lowering of loads.
Liebherr electric motors are designed for a constant nominal torque from standstill up to the rated speed. For speeds above the rated speed, the motors retain continuous output up to 4,500 rpm.
Liebherr alternators are available in both synchronous and squirrel cage versions. Optimally adapted to the respective application, the alternators offer excellent efficiency in continuous operation and variable speed applications.
