Show transcribed image text R 1) A dc machine has and armature resistance of RA = 2.0 ohm The machine is attached to a load given by TL = 0.01 ohm The motor has the field maintained such that kE = kT = 0.4 Vs. Find the terminal voltage required by the machine to operate at a speed of 100 rad/s. Find the efficiency of the machine under this condition. Do a PSPICE simulation of the machine under this operating condition. R2) The dc machine of problem Pl is connected to a 24 V source. The field is then adjusted to get 75 rad/s. Find the new value of kE and the efficiency under this operating condition. R3) Do a PSPICE simulation to determine verify the results of R1 and R2. A steady state bias calculation should be acceptable for this calculation.
