Liebherr unveils permanent magnet electric motor for off-highway equipment

Liebherr, a German-Swiss equipment manufacturer based in Bulle, Switzerland has introduced a new permanent magnet electric motor specifically for use in off-highway equipment.

The motor offers the same power density as a hydraulic version, but the use of a permanent magnet electric motor will eliminate the need for the installation and maintenance of multiple hoses and other components required by hydraulic systems, which will lower overall machine weight as well, according to the company. The motor features an oil-cooled design developed specifically for use in battery- and diesel-electric traction drives. This will allow for quick installation and simplified electrification of existing hydraulic drive concepts, Liebherr said.

Liebherr was presented with an innovation award on the eve of the opening of the Bauma trade show in Germany. The innovation award recognizes groundbreaking developments in five categories within the construction, construction materiel and construction machine industries. The award for “digitalization” was given to Liebherr for a product called Liebherr Autonomous Operations, which works with multiple product offerings including the Liebherr S1 Vision 140-ton autonomous hauler the company is developing.

Liebherr has production sites in over a dozen countries, including Australia, Ireland and the United States, and its main production facilities and origins are in Germany. The company was founded by Hans Liebherr in 1949. Liebherr, when he opened a production site in Killarney, Ireland, found that the local hospitality industry was virtually nonexistent in the area and that the simple guesthouse he had planned to build would not suffice. He therefore took lakefront property he had acquired for a factory and built his first hotel, the Europe. The company now owns six hotels, including three in Austria.
