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.

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.

Overview of possible materials:
(All copper-based materials are produced in-house and are available in various strength levels)

Through our unique and patented Laminar Squeeze Casting technology, Wieland eTraction Systems has succeeded in developing the Zero Porosity Rotor - ZPR®. As shown in the CT scans below, we outperform the industry in both the copper and aluminum rotors.  

As a result, Wieland eTraction Systems is quality leader within the global rotor manufacturing industry, offering the ZPR® from the smallest sample lot to volume production. 

The benefits of a Zero Porosity Rotor - ZPR® are as follows:

• Unique product quality
• Stable process capability 
• Significantly higher electrical conductivity 
• Higher efficiency of your electric motor

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.
