About LOHO Elektromaschinen
LOHO Elektromaschinen GmbH, based in Murnau (Upper Bavaria), is a manufacturer-independent service provider for power generation and electrical machine engineering. The company offers an all-round service package: assembly of new generators, commissioning, modernization with digital controllers, inspection and maintenance as well as repair and overhaul on site and in its own workshop. The service spectrum includes rewinding of winding components, core stack renewal, laser-supported alignment, on-site balancing and diagnostics such as vibration analysis, partial discharge and dissipation factor measurement. In the company's own assembly crane hall, electrical machines up to 20 tonnes individual weight are tested and serviced. In addition, the offering includes service for motors, gearboxes and pumps, secondary protection testing of systems up to 100 MVA via partner companies, the manufacture of special machines for orthopaedic technology, and factory representation for Sulzer lift stations and industrial pumps. Customers come from power generation, industry, combined heat and power plants, hydroelectric power plants and wastewater/supply and disposal; service is provided nationwide, Europe-wide and worldwide.
