In an electric motor, the electromagnetic torque developed is
In opposite direction to both load torque and frictional torque
In an electric motor, the electromagnetic torque developed is in opposite direction to both load torque and frictional torque.
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
