explain the principal of working of simple electric motor what is role of split ring in a electric motor? how are commercial motors different from simple electric motor
Answers
Answer: The principle of an electric motor is based on the current carrying conductor which produces magnetic field around it. A current carrying conductor is placed perpendicular to the magnetic field so that it experiences a force.
Split ring is used for reversing the direction of current in the coil. ... Therefore, after every half rotation of the coil the direction of the couple rotating the coil remains the same and the coil continues its rotation in the same direction.
In commercial electric motors, field coils are used for producing magnetic fields and not a permanent magnet as in simple electric motors. These coils become magnetized when current is passed through them. ... Therefore, the suitable field coil sizes are used for various commercial purposes.
