我可以作一个小小的赛道与直流电动机来衡量的实际输出功率的引擎在不同进气压力。
I may make a small dyno with a DC motor to measure the actual power output of the engine at various intake air pressures.
它们都工作在300千赫兹，直流母线电压400伏特，输出功率120瓦特，输出电压16伏特。
All of them have been operation at 300 kHz, bus voltage of 400 V, output power of 120 W, output voltage of 16 V.
若将他励直流电动机输出功率的机理等效为一个与电动机电枢绕组并联的可变电阻，可以得到他励直流电动机可变电阻型等效电路图。
The output power mechanism of a separately excited DC motor can be equivalent to a variable resistance, which is parallel with the armature winding of the motor.
