A DC motor delivers power to a load at a speed of 2250.0 r/min. The armature current drawn by the motor is Ia = 15 A. The armature circuit resistance of the motor is R = 6.4 Ω and total losses are Pf = 1440.0 W. On the motor nameplate it says U = 320 V and P = 2100.0 W. a) Convert angular velocity: b) Determine voltage induced in rotor: c) Calculate the power to the motor d) Determine the mechanical power delivered by the engine:
