READ MORE· Working Principle of Synchronous motor : Synchronous motor works on the principle of the magnetic locking. When two, unlike poles, are brought near each other, if the magnets are strong, there exists a tremendous force of attraction between those two poles. In such condition, the two magnets are said to be magnetically locked.
