Overview


Traditional loading methods include eddy current dynamometer, hysteresis dynamometer, magnetic powder brake, etc.Low speed eddy current load performance is not good, low speed can not even load; Magnetic powder brake can not be used in high-speed occasions, and hysteresis dynamometer can not be used in high-power occasions, and the above types of dynamometer are required to install cooling water circulation system.This system does not need auxiliary cooling facilities, which brings great convenience to use.





Application



With the unique digital control device, the electric dynamometer has two operation states of electric power and dynamometer, which can run in the four-quadrant state. It can be used for generator operation and motor operation.It can be loaded forward or backward.





Benefits at a Glance



During dynamometer operation, the mechanical energy of the generator is converted into electric energy consumption (feedback to the power grid), which saves energy, and its energy-saving effect is very obvious.
Constant torque and constant speed control stability is unmatched by other loaders, it can maintain extremely high stability (0.1-0.3%) in the full speed (even at zero speed) and torque range.​




Specifications



Accuracy of torque measurement accuracy ±0.05%F.S Depends on the accuracy of the torque sensor
Accuracy of speed measurement 0.1%±1r/min
Constant speed control stability 0.1%


overload capacity

136% 60 seconds
Rated torque:cycle in 300 seconds
Torque step rise time DC: at rated torque: 5ms
Step rise time of rotating speed AC: at rated speed: 20ms It's related to the inertia of the motor
