The magnetization curve of a 100-Volt series DC motor is shown in the figure below. At full-load, the motor draws 60 A from the DC power supply at a speed of 800 rpm. The motor has an armature resistance of 0.25 ohm and the resistance of the field winding is 0.15 ohm. There are 20 turns per pole in the field winding. Answer the following questions: a) Find the no-load speed of the motor. b) Find the speed of the motor for an armature current of 30 A. (Ignore armature reaction). c) Calculate the induced torque of the motor for the conditions in part (b). EA (Volt) 145 140 120 spe lA 100 30 70

Transcribed Image Text:The magnetization curve of a 100-Volt series DC motor is shown in the
figure below. At full-Hoad, the motor draws 60 A from the DC power
supply at a speed of 800 rpm. The motor has an armature resistance of
0.25 ohm and the resistance of the field winding is 0.15 ohm. There are
20 turns per pole in the field winding.
Answer the following questions:
a) Find the no-load speed of the motor.
b) Find the speed of the motor for an armature current of 30 A. (Ignore
armature reaction).
c) Calculate the induced torque of the motor for the conditions in part
(b).
