Extracted text: A 150 V, 6-poles lap wound DC motor has an armatre resistance of 0.5 2. The number of conductrors of the armature winding is 500 conductors. The armature draw a current of 20 A when the magnetic field is 15 mwb. If the total copper losses is 0.5 kW. Draw the circuit with indication all values and find: i) The motor speed ii) Themotor torque iii) The devloped power iv) The copper losses in the field winding v) Thefield resistance
