Thanks to our patented cut and fill technology, we succeed in filling the rotor in a uniform and controlled manner and thus create the basis for the optimal performance of your e-motor.

The fields of application of copper rotors can be divided into two classes.

Rotors for industrial motors: Here the rotational speeds are often less, so that we can work with pure copper as the rotor material.

Rotors for e-mobility: Outstanding motor efficiency is achieved here for high rotational speed concepts. The copper rotor is under strong mechanical stress caused by the centrifugal forces of the rotating mass. The required rotational speed of a given rotor diameter determines whether it is possible to use technically pure copper. If the threshold is exceeded in relation to thermo-mechanical loads, we recommend our pure copper mircoalloy, which offers increased tensile strength and high temperature strength.

CORE COMPETENCE

The core competence of Breuckmann GmbH & Co. KG is high pressure die casting with raw materials whose the casting exceeds the threshold of 1000°C.

The high pressure die casting process offers ideal conditions for the economic manufacture of precise castings with a high surface quality.

We primarily cast silicon tombac, pure copper and brass for customers in the lock and fitting industry, the electronics and automotive industries in addition to general mechanical engineering.

High pressure die casting at temperatures of over 1000°C is remarkable as the same steel moulds are used again and again, even though these moulds melt at temperatures of approx. 1500°C. Thanks to 50 years of experience in this area, we succeed in delaying the heat-related wear to the mould at such high temperatures, and we also manage to efficiently repair once worn-out moulds. This know-how allows us to combine excellent casting properties with an extremely economical production process, all to the benefit of our customers.

Our great production depth and exceptional innovation expertise differentiate us from our competitors. The company’s commitment to these objectives is seen in the high demand for scientific education and training among our engineers and management and, not least in the substantial investment volume we have made over the past years. Today, Breuckmann GmbH & Co. KG is one of the most modern foundries in the market and a powerful partner with solutions for your tasks.

This makes us strong: All the steps involved in the production of our products are carried out in-house. Direct access to all departments guarantees us lasting quality and flexibility.
