Patented wave spring for EV market 08 October 2024

The new patented InterShim™ wave spring design from Rotor Clip has been engineered for high acceleration electric motor applications and features alternating turns between inactive (flat) and active (waved) turns to ensure reliable performance under torsional loads and precise rotational movement.

While initially developed for Electric Vehicle (EV) applications, Rotor Clip’s Intershim™ wave spring offers benefits that extend far beyond the automotive industry. It is highly customisable, with options open for the number of waves, number of turns, the arrangement of shims/troughs as well as a variety of speciality alloys. The option of either floating ends or bent ends also helps prevent damage to the mating surface during application. 

Intershim™’s advanced design addresses physical challenges such as extreme forces and vibrations, making it a versatile solution for high-speed and high stress applications across various industries. 

“The development of the new wave spring design represents a significant milestone and underscores our dedication to meeting the evolving needs of our customers. By listening to feedback, and leveraging our expertise, we have engineered a solution that offers unparalleled performance in high acceleration applications. We are proud to introduce this design to the market and look forward to its positive impact on our customers’ operations,” reported Elmar Kampmann, European sales engineering director at Rotor Clip Ltd.
