Materials

Wieland offers you ready-to-install copper rotor bars of consistently high quality at maximum cost efficiency. This is guaranteed by our fully automated processes across the entire value stream.

In addition, the rotor bars can be manufactured in complex geometries, varying lengths, straight or twisted, and with or without notches. This enables unique rotor designs - from development to series product - from the smallest sample batch to mass production.


Wieland manufactures rotors in copper and aluminum for highly efficient induction motors. This enables you to meet the increasing need for energy efficiency and economy without the need for rare earth minerals.
We also offer engineering support during the development of your application-specific design. Furthermore, Wieland offers two different processes to produce rotors to meet your individual requirements. Both processes offer manufacturing with a very high degree of material filling without air inclusions, and we can draw on a wide range of experience from prototypes to series production.

The fabricated Wieland copper rotor is a new and innovative design, which is designed according to your requirements. Due to the disc-shaped design of the short-circuit ring, different materials can be combined individually, and fulfill the requirements for higher power densities and rotation speeds.

Additionally, the fabricated design has a higher mechanical strength and enables a very scalable, flexible, and economical approach for rotor production.

Wieland's high-voltage components are hybrid components in which plastics are combined with copper alloys. With our distinctive knowledge in stamping, forming, laser welding, plastic injection molding, and automation; Wieland is already a long-standing component supplier in the field of e-mobility.
We offer individual solutions and support in development by taking DFM (= Design for Manufacturing) into account and can also offer prototypes from our prototype shop. We are happy to accompany you through all sample phases up to series production.

For contacting in the electric drive train or between the battery and the electric machine, Wieland offers you a wide variety of designs (e.g. fully overmolded; assembled) of ready-to-install connector units and overmolded busbars. The design of these is based on your requirements, which enables contacting in the tightest of spaces.
To evaluate your design and the corresponding requirements, please contact us via the contact address below.


The electron beam welded multi-metal strip can consist of up to five alloys. The stripes are also available in various dimensions, plated, or unplated. Large quantities of our multi-metal strips are supplied on coils. However, the delivery of piece sheet metal for prototypes is also possible.
We carry out all process steps in-house, and because of this we can find the best alloy combination for your application. Our offerings don’t end at only using our alloys. We also can evaluate using materials and alloys from other manufacturers.

With the use of our specially developed resistance alloys, electron beam welded multi-metal strips are ideal as pre-material for shunts.


Shunt resistors provide highly accurate and reliable current measurement over a wide temperature range, leading to a better battery management. Shunts are manufactured from an electron beam welded multi-metal strip using our specially developed resistor alloys.
Wieland offers shunts in various standard dimensions as well as customized designs. For this purpose, development, sample, and series production are located in-house.

Our standard shunts are designed according to uniform sizes and resistance values.


Currently, the Wieland portfolio includes the following basic shunts.
