Motor and Generator Components
Whatever the source of power is, Luvata makes it happen
Luvata's offering includes rotor copper components for motor and generator applications.
The quality requirements are high for both all measures and surface and typically only oxygen-free copper can be used for this application.
Rotor bars are manufactured according to customers specifications, so all of these may have special features that make these products perfectly suited to your needs.We can offer ready to install rotor bars.
Depending on the requirements, we can:
- Cut the product to length according tight tolerance when needed
- Bars delivered burr free
- Brushed surface and machined to the required shape
- Customized packaging
The products will be delivered to you at a competitive delivery time from the smallest sample to lot mass production.
Luvata has long experience in manufacturing d-sections. Thanks to our capable process, we can offer a cross-sectional area of 4 mm2-9000 mm2. Even larger cross-sections are possible through the forging process.

Luvata’s seamless copper hollow conductors are typically used in power generator stator and rotor windings. Stator tubes are rectangular shape hollow conductors made from oxygen free copper grade. We supply also slightly hardened stator tubes for generators which specifications require higher mechanical strength.
Rotor tubes are mainly manufactured using silver bearing copper alloys. Small amount of alloyed silver increase the softening temperature of pure copper and the mechanical properties at elevated temperature are higher than in pure copper. Like our other oxygen free copper grade, silver bearing copper can be joined with all welding and brazing methods and it is suitable for manufacturing processes requiring extreme deformability.
Our hollow conductors have been used in different size of generators over five decades. We have a long experience in manufacturing these demanding products for turbo generators as well as smaller air cooled generators.
Our offering for stators include thick wall OF-OK tubes for high voltage terminals and phase rings.
Oxygen-free copper ensure high electrical conductivity and can be joined safe by all joining methods without risk of hydrogen embrittlement. The tubes are manufactured to customer's specification and after final testing can be cut to a set of different lengths.
