Unmatched Performance of Our Electric Dynamometer:
In constant speed mode, the Electric Dynamometer excels with both driving and reversing capabilities.
In constant torque mode, the Electric Dynamometer delivers exceptional dynamometer loading performance.
In the dynamometer loading state, the energy generated by the electric dynamometer can be efficiently fed back to the grid directly or dissipated through the chopper brake resistor.
Electric dynamometers eliminate the need for a cooling water system, simplifying operation and reducing maintenance costs.
