Why dc shunt motor in lathe, compound motor in rolling mills
Answer Posted / karan sharma
Lathe machine operation needs linear torque nd this is done in DC shunt motor i.e constant torque at constant current i.e linear torque. While rolling mills can have diffrent values of torque while considering its operation in certain applications, which can be provided by compound motor i.e b/w series nd shunt.
