The mechanical power developed by a dc motor maximum is maximum when
Back emf is equal to half the applied voltage
The mechanical power developed by a dc motor maximum is maximum when Back emf is equal to half the applied voltage.
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
