Rotors

Centrifugal Force Test / Spin Test / Burst Test and Finite Element Analysis
PLB Test Laboratory for Operating Strength GmbH

Test options at Rotors of electric motors:

- Static and dynamic deformation measurement at the commutator and at rotor metal sheets with
eddy current sensors and laser measurement systems

- Burst testing of rotors at maximum permissible operating temerature

- Highspeed videos of the fracture mechanics
