Unformatted text preview: c) What is the power flowing into or out of the machine? What is the torque? Neglect losses. d) If the speed were changed to 550 rad/s what would happen to the current? If the speed were increases to 550 rad/s the induced voltage would increase to 55 volts and the current would increase to 17.5 amps. e) If the speed were changed to 450 rad/s what would happen to the current? If the speed were decreases to 450 rad/s the induced voltage would decrease to 45 volts. Since this is less than the battery voltage current would flow into the loop and the machine would act as a motor. The resulting current would be 7.5 amps. Question 2....
