<p>A fuel engine load servo device comprises a permanent magnet motor which has a first rotor and a second rotor, the first rotor being directly connected to the output shaft of the fuel engine, the second rotor being directly connected to the driving shaft, and the first rotor and the second rotor transmitting power each other by electromagnetic coupling, wherein the fuel engine load servo device also having a servo driver which controls the electromagnetic torque between the first rotor and the second rotor according to setting condition, so as to control the torque loading of the fuel engine and the output torque of the driving shaft; a speed/ position sensor disposed on the first rotor shaft, a position sensor disposed on the second rotor shaft, and an electric slip ring disposed on the rotor shaft of the coils to connect the coils with the servo driver. The invention can make the engine always operate on the optimal fuel consumption curve and output maximal power on same fuel consumption.</p> |
