Repair and service of electrical machines since 1919
egm Elektrotechnik GmbH in Moers specialises in the service, maintenance, repair, conversion and new construction of electric motors and generators. Its experience in electrical machine engineering dates back to 1919. The range of services includes rewinding of stators and rotors, general overhaul/overhaul, vacuum pressure impregnation, commutator repairs, blasting and painting, as well as dynamic balancing of rotors up to 10 tonnes (Lmax 6,000 mm, Dmax 2,100 mm). In its own test field, no-load and short-circuit characteristics, load test runs, electrical measurements as well as vibration and temperature measurements are carried out. The company handles AC and DC motors, generators, converters, transformers and traction drives – including Ex-protected motors with ATEX inspection (licence from the state of North Rhine-Westphalia) and high-voltage machines. Customers come from industry, chemicals, railway technology, wind energy, energy technology (CHP), the steel and metal industry and conveying technology. Within Germany and the Benelux countries, the service team guarantees a standard response time of less than 24 hours; in addition, DC replacement motors and spare parts are manufactured to drawing or sample.
