Why is rotor field winding excited by DC but not AC?
I see. Does the frequency of the AC current have any effect on the motor's performance?
Yes, the frequency of the AC current determines the speed of the motor. A higher frequency will result in a faster motor speed, while a lower frequency will result in a slower speed. However, it's important to note that the frequency should still be within a certain range for the motor to run properly.
