Stator windings
On the following sites we offer you an overview of possibilities in manufacturing stator windings.
AC round wire windings
This manufacturing area has specialised on the production of round wire windings in single-layer, double-layer or specialised designs. Modern production technologies are used, such as: winding machines, infeed devices, slot folding machines and welding equipment. Find out more:
Three-phase diamond coil windings
One of the most important components of our company is the production of preformed windings with profi led wire. The smaller dimensions of preformed coils are primarily produced for traction machines. The largest dimensions can be produced up to a fi sh length of 5.6 m. The individual coils can weigh up to 60 kg and are produced on special preformed coil forming machines. Pole numbers from 2 to 24 are possible.

Roebel bar windings
For generators up to approx. 30 MVA and for special motors, so-called Roebel bar windings are used. These bars, consisting of a large number of individual braided strands, make possible improved current distribution within the slot, resulting from current displacement phenomena.
Field coil windings
The pole coil winding is a component of synchronous machines, among others, and is typically found on rotors. These coils are wound or plugged directly on the pole. They are available in different versions (from insulated fl at or round wide, wound on edge from bare copper or soldered together from individual copper parts). The individual coils are switched together so that the form an alternating north and south pole when excited by direct current.
