The mechanical output available at the dc motor shaft is equal to
Electrical power input less total losses (copper loss, iron loss, friction and windage losses)
The mechanical output available at the dc motor shaft is equal to Electrical power input less total losses (copper loss, iron loss, friction and windage losses) .
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
