In a dc compound motor, 4-point starter is employed not to affect the current flowing through Hold On coil even when the field current changes.
A dc shunt motor is driving a constant torque load with normal excitation. If the filed current is halved then the motor will run at
A dc shunt motor is driving a mechanical load at rated voltage with normal excitation. If the load torque is increased to double of the normal one, the speed of the motor will
