AI Technical Summary
Technical Problem
Existing methods for testing crimp connections in electrical machines, such as those in traction motors, fail to simulate real-world stress conditions, leading to inaccurate predictions of service life and requiring complex, resource-intensive system tests.
Method used
A dynamic testing method that applies cyclic loading to crimp connections, simulating centrifugal forces and other operational stresses, allowing separate testing of assemblies without the entire system, using a device that monitors connection parameters under controlled conditions.
Benefits of technology
Enables precise determination of fatigue strength and load-bearing capacity, improving design reliability and reducing costs by allowing faster, more efficient quality monitoring and resource use.

Abstract
Method for testing an assembly (2) for an electric machine, in particular an externally excited synchronous machine, comprising two electrical conductor elements (3, 4) which are connected to one another by a crimp connection (5), wherein the crimp connection (5) is cyclically loaded, in particular by applying a test force to one of the conductor elements (3, 4), wherein a connection parameter of the crimp connection (5) is determined.
