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] ]

Large / special motors

Our particular strengths

Tailor-made motors – design, manufacture and reverse engineering of rotating
machines. HELMKE is specialised in made to specification motors. HELMKE can offer direct 'drop-in' replacements for their own or other manufacturer machines. Through application of motors with higher power rating, but identical dimensions and mounting, the turnover and efficiency of the user’s plant will be increased significantly. Flexible manufacturing procedures allow customer specific products which will perform in the most demanding environments:

  • Reduced losses for optimized efficiencies
  • Design for low noise emissions
  • Low starting currents while maintaining high starting torque
  • Keyed bar rotor cage construction providing extremely rugged rotor construction
  • Design flexibility
  • Optimised stator and rotor slot numbers, independently selectable
