Explain the United States' tremendous success story in postwar Japan versus its failure in China. Who was responsible for the fall of China to the communists? Did American postwar foreign policy toward Nationalist China and its leader Jiang Jieshi play a crucial role in the fall of China? Alternatively, were the keys to the "loss of China" to be found in the shortcomings of the Nationalist government and the political and military strength of Mao Zedong and his communist armies?
What will be an ideal response?
A bipolar BLDC motor with k? = 1.0 Vs is running at 500 rpm when the modulation factor is 80% and the load torque is 30 Nm. The voltage of the dc source is 200 V, and the armature resistance of the motor is 1.0 ?. Compute the dynamic braking resistance that would limit the braking current to 160% of the pre-braking condition. If the torque is unidirectional, compute the steady-state speed of the motor.
