TESTING
Pushing Limits – at Zoerkler's State-of-the-Art Test Center
Zoerkler operates one of Europe's most advanced test centers for drivetrain systems. Our state-of-the-art test benches are designed to push systems to their limits and beyond – under real-world conditions. We develop and manufacture custom test benches tailored to specific customer requirements, including full certification, performance analysis, and failure diagnostics.
High-End Test Benches for Aerospace, Automotive & E-Mobility
Main Gearbox Test Bench for Helicopters
Unique in Europe: Enables indoor testing of conventional and coaxial helicopter gearboxes – ideal for the aerospace industry.
E-Drive Test Bench for E-Axles
Developed, built, and assembled by Zoerkler for testing electric axles. The flexible layout supports gearbox and single-stage motor testing, including a 300 kW battery simulator for realistic e-mobility conditions.
Hydraulic and Pump Test Bench
Designed for testing individual hydraulic components and complete systems. Includes dry-run capability, leak rate testing, and flow analysis under variable oil pressure and temperature conditions.
Fatigue Limit Test Bench
For highly stressed driveshafts and gears: Determines torque strength limits and finite lifetime at up to 1500 Nm average load and ±500 Nm amplitude at approx. 6 Hz test frequency.
Rotor Brake System Test Bench
Our test bench includes a device for simulating rotational inertia. This allows for reliable testing of vibrations, concentricity, and stability. Additionally, the simulation of rotational mass enables targeted evaluation of rotor brake systems in terms of performance and endurance.
Universal Gearbox Test Bench & Tail Rotor Shaft Test Bench
Suitable for tail gearboxes, intermediate gearboxes, automotive gearboxes, and – with adaptations – e-mobility gearboxes and electric motors. The tail rotor shaft bench allows precise testing of vibration, runout, and stability.
