Eddy Current Dynamometer /Eddy-Current Brake Dynamometer

Eddy-Current Brake Dynamometers are perfect for high-speed applications and those with middle to high power requirements. These dynamometers deliver increasing torque as speed rises, reaching peak torque at rated speed. They are designed with low inertia, thanks to their small rotor diameter, making them ideal for fast and efficient performance.

Key Features:

• Torque increases with speed, peaking at rated speed
• Low inertia design with small rotor diameter
• Water-cooled system for heat dissipation
• High continuous power ratings up to 140 kW
• Accuracy of ±0.2% to 0.5% full scale

Options:

• High-speed version (up to 65,000 RPM)
• Speed pickup
• Mechanical rotor blocking device
• OEM version IS
• Vertical mounting

Operating Principle:
Eddy-Current Dynamometers use electromagnetic induction to generate braking force. As the conductive rotor spins in a magnetic field, eddy currents create opposing forces, allowing precise load control。

Eddy current dynamometers are especially suited for

• Development and testing of all kinds of power engines
• Quality control, running-in and endurance testing of combustion engines
• Components tests such as valve actuation, injection systems and ignition systems
• Fuel and lubricating oil tests with engines

Benefits

• High speeds for testing of passenger cars engines
• High torques at very low speeds for commercial vehicle engines
• Large attachable masses allowing the use of several connecting shafts
• Suitable for two rotating directions
• High measuring accuracy due to contact-free speed measurement via a pulse generator as well as torque measurement via a load cell
• Robust design, which integrates the load cell inside the frame
• Long life time circle resulting from new mechanical design of cooling chambers and water pipes
• Easy maintenance due to optimised mechanical design
• Cooling chambers and coil can be changed without dismantling the bearings
• Self-monitoring (cooling water)
