Question

P 16.3 1of4 Review Part A A four-pole induction motor drives a load at 2636 rpm. This is to be accomplished by using an electronic converter to convert a 400-V dc source into a set ot tnree phase ac voltages. Find thB frequency required for the ac voltages assuming that the slip is 4 percent. The load requires 2 hp. Express your answer to three significant figures and include the appropriate units. 91.5 He Previous Answers Correct Significant Figures Feedback: Your answer 91.53 Hx was either rounded differently or used a different number of significant figures than required for this part Part B If the de-to-ac converter has a power efficiency cf 89 percent and the motor has a power efficiency of 80 peron, estimate the current taken froTi the die source. Express your answer to three significant figures and include the appropriate units. I-alue Units Submi Next > Provide Feedback
