Electric motors

Liebherr electric motors are compact, robust and maintenance-free three-phase squirrel cage motors with high power density. Down to the smallest size - round model BG 132 - all motors are designed with a self-supporting stator core, which supports the housing in addition to the electrical functions.

The engines have been specially designed for operation in variable-speed drives with frequency converters and also for highly dynamic applications. They are designed for a constant rated torque from standstill to the rated speed and in addition for constant power.

The electrical design and the construction principle offers a low volume-performance ratio in combination with the effective cooling. The compact design means low noise level and very quiet operation. All models can be fitted with the required attachment components (external fan, tachogenerator, incremental encoder, rotary encoder, centrifugal switch) in a modular system and are suitable for a wide range of applications.
