• Compatible with computer control systems

The CARTESY engine dynamometer system comprises:

• Professional measurement & control software
• Intelligent control system
• Eddy current dynamometer unit
• Driver assistant system
• Dedicated control cabinet
• Complete supporting accessories

The eddy current unit consists of stator, rotor, electromagnetic coils, and electromagnets on both sides. It operates based on electromagnetic principles where eddy currents are generated when a moving magnetic conductor cuts magnetic lines of force, creating resistance torque.

When electric current flows through the electromagnets, a magnetic field is generated. Simultaneously, strong eddy currents are produced on the rotating rotor, converting electrical energy into thermal energy. This heat is dissipated into the air by the rotor cooling fan, creating friction-free resistance between the stator and rotor.

Where:
N – Load, Unit: Newton (N)
n – Rotational speed, Unit: r/min

Where:
N – Load, Unit: Newton (N)
L – Calculated arm length, fixed at 0.95493 meters

Note: For quick and convenient brake power calculation using dynamometer force measurement readings, a weight arm length of 0.9738 meters or its simple multiple is adopted. During static calibration, 1kg weight corresponds to 10N display value or its multiple, confirming the calculated arm length as 0.95493 meters.
