New Factory in SarstedtIn addition to the existing plant, a new state-of-the-art manufacturing facility is under construction at the HELMKE site in Sarstedt (near Hannover, Germany).[ [more] ]
Drive systems - engineered by HELMKEHELMKE is a worldwide acknowledged competence for the delivery of complete drive systems. The converter cabinets engineered by HELMKE are projected and manufactured for customized and branch-specific applications.[ [more] ]
Windings - Highest quality in production and delivery
In our workshops, equipped with state of the art technology, windings for new machines as well as for repairs of low, medium and dc voltage machines are produced. Our capablilities include:
