Rotor Bars

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.

Materials

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.

K65 - Sustainable and efficient

Sustainable and efficient – two keywords that have had a decisive impact on our time and have gained in relevance in recent years, especially in refrigeration. Increased environmental awareness in society and industry has therefore led to a kind of renaissance of natural refrigerants, especially CO₂. Wieland supports this turnaround with a tube system that meets the high requirements of CO₂ as a refrigerant.

Wieland K65 tubes have been designed for CO₂ applications in the commercial field, especially that of supermarket refrigeration systems. Wieland K65 alloy provides the mechanical strength high enough to withstand the high operating pressures of CO₂. At the same time, K65 tubes have outstanding processing properties, similar to those of standard copper (Cu-DHP/C12200).

All Wieland K65 tubes are available in the soft condition (R300/O61) to ensure excellent bending / flaring and collaring properties.

Wieland K65 tubes are offered from stock in two pressure ranges, 80 bar and 120 bar, and in dimensions ranging from 3/8” up to 2-1/8”.

Moreover, K65 tubes are also available in individual dimensions and different delivery forms.
For industrial processing, in particular CO₂ heat exchanger (evaporator / gas cooler) manufacturing, level wound coils (LWC) are offered.

K65 - Sustainable and efficient

two keywords that have had a decisive impact on our time and have gained in relevance in recent years, especially in refrigeration. Increased environmental awareness in society and industry has therefore led to a kind of renaissance of natural refrigerants, especially CO2. Wieland supports this turnaround with a tube system that meets the high requirements of CO2 as a refrigerant.

Wieland K65 tubes have been designed for CO2 applications in the commercial field, especially that of supermarket refrigeration systems. Wieland K65 alloy provides the mechanical strength high enough to withstand the high operating pressures of CO2. At the same time, K65 tubes have outstanding processing properties, similar to those of standard copper (Cu-DHP/C12200).
Wieland K65 tubes are offered from stock in two pressure ranges, 80 bar and 120 bar, and in dimensions ranging from 3/8” up to 2-1/8”.

All Wieland K65 tubes are available in the soft condition (R300/O61) to ensure excellent bending / flaring and collaring properties.

Other dimensions and delivery forms such as level wound coils are offered for industrial processing, in particular manufacturing of CO2 heat exchangers (evaporator/gas cooler).
