Eddy Current Dynamometer
An eddy current dynamometer is a non-contact load device that generates braking torque through electromagnetic induction. As the conductive rotor spins inside a magnetic field, opposing eddy currents create a precise, controllable braking force. Load is adjusted by changing the excitation current through external coils. No mechanical contact means minimal wear and highly repeatable measurements.
EconoTest ECW series eddy current dynamometers cover speeds up to 50,000 دورة في الدقيقة. The ECW05KB model (0.5 نانومتر) reaches 50,000 RPM for high-speed micro-motor testing; the ECW300KB model (300 نانومتر) handles speeds up to 7,000 RPM for large industrial motors. All models are water-cooled.
لا. Eddy current dynamometers cannot generate braking torque at zero RPM because the braking force depends entirely on rotor motion through the magnetic field. For zero-speed torque testing, starting torque measurement, or servo motor evaluation, a hysteresis or magnetic powder dynamometer is required.
All ECW series eddy current dynamometers are water-cooled. Short-term power ratings range from 200 دبليو (ECW05KB) ل 25,000 دبليو (ECW300KB); continuous ratings from 120 W to 15,000 دبليو. Water supply flow and pressure requirements are specified per model. The water circuit must be kept clean to maintain heat exchange efficiency.
ECW series eddy current dynamometers achieve torque accuracy of ±0.2% to ±0.5% full scale. The exact accuracy depends on the model and measurement range selected. Load cell-based torque measurement with non-contact speed pickup ensures consistent repeatability across test sessions.
Eddy current dynamometers excel at: high-speed electric motor performance testing, EV motor power and efficiency mapping, combustion engine development and calibration, quality control and endurance testing for motors up to 300 نانومتر, NVH testing, and high-speed component testing where low rotor inertia is important.
