A four-pole induction motor drives a load at 2405 rpm. This is to be accomplished by using an electronic converter to convert a 400V dc source into a set of three-phase ac voltages. a) Find the frequency required for the ac voltages assuming that the slip is 4 percent. The load requires 2hp. b) If the dc-to-ac converter has a power efficiency of 93 percent and the motor has a power efficiency of 80 percent, estimate the current taken from the dc source.
