Top performance at high speeds
Powerful drives thanks to precise balancing The trend toward higher speeds amplifies the effects of imbalances. Therefore, reliable and high-quality balancing is becoming increasingly important to ensure functionality and quality. With Schenck balancing machines for electric anchors, you can ensure smooth running and a long service life for electric motors. Benefit from maximum performance in a compact design and completely balance (electric) anchors in just one pass.
Flexibility and quality for your manufacturing processes Our balancing machines for electric motors combine versatility and high balancing quality. Thanks to quick changeovers to different rotors, good accessibility, simple controls, and linear units with locking positions, you can make your production processes even more efficient with the eTENO.
Spinning stands: key components in electromobility Spinning stands are indispensable for the development, prototype testing, quality assurance, and production of electric rotors. Due to the low imbalance tolerances of electric rotors, the spinning process and subsequent balancing are crucial. Spinning stands are indispensable in the development, production, and quality assurance of rotors in the field of sustainable mobility. A special quality feature of our spinning stands: The vacuum-tight container with integrated burst protection is dimensioned to absorb the expected fragment energy when a rotor bursts.

Centrifugal testing – centrifuge testing for research, development, and production.
-
When rotors are subjected to high centrifugal forces during operation, you need to be sure that they will not permanently deform or burst. Proven methods include strength tests and durability tests at speeds above the operating speed, burst tests, or life cycle tests using cycle testing. This gives you the assurance you need for the operation of your rotors. We perform a wide range of necessary tests on your rotating components for new and further developments or as part of quality assurance.
Our centrifugal tests at the Green Technology Center offer you modern analysis options and customized services for your requirements.
With the Centrio centrifugal test rig from Schenck, you get a highly efficient solution for centrifugal testing in your company. With significantly reduced noise emissions, low energy consumption and space requirements, and carefully perfected ergonomics.
