1.A 230 V shunt motor has a nominal arma- ture current of 60A. If the armature resist- ance is 0.15 N, calculate the following: a. The counter-emf [V] b. The power supplied to the armature [W] c. The mechanical power developed by the motor, [kW] and [hp] 2.a. In Problem (a) calculate the initial start- ing current if the motor is directly con- nected across the 230 V line. b. Calculate the value of the starting resistor needed to limit the initial current to 115 A. 1.A 230 V shunt motor has a nominal arma- ture current of 60A.
