How Does the Eddy-Current Brake Dynamometer Work?

Der Bremsdynamometer mit Wirbelströmung uses electromagnetic fields to apply braking force without physical contact. Here’s how it works:

Eddy-Current Principle: The dynamometer’s rotating drum generates an electromagnetic field that induces eddy currents in the brake system being tested. This interaction produces a resistive force, simulating the braking action.
Dynamic Load Simulation: By adjusting the strength of the electromagnetic field, the system can precisely simulate dynamic braking loads, including deceleration, stopping, and energy recovery.
Eddy Current Dyno Heat Simulation: The dynamometer can replicate high-stress braking conditions to test the heat dissipation properties of the braking system, ensuring that components are tested under realistic conditions.
Real-Time Monitoring: All test data is collected in real-time, providing engineers with immediate feedback on the brake system’s performance.
