Split ring is used for reversing the direction of current in the coil. For the continuous rotation of the coil in the same direction, the current in the coil must be reversed.
What is the function of split ring in electric motor Class 10?
The purpose of split ring is to reverse flow of current after every half rotation of the coil and make coil rotate in a single direction. If split ring was not used in an electric motor, the coil would have rotated half in clockwise direction and half in anticlockwise direction.
What are split rings?
1 : a metal ring which consists of two complete turns of a helix pressed flat together and upon which objects (such as keys) may be strung. 2 : a primitive form of commutator for a dynamo or motor consisting of a simple ring or cylindrical shell split axially with the parts insulated from each other.
What is the difference between a split ring and a slip ring commutator?
A split-ring commutator makes the current change direction every half-rotation, whereas a slip-ring commutator merely maintains a connection between the moving rotor and the stationary stator.
What is the basic principle of electric motor?
The electric motor works on the principle of magnetic effects of current. Its principle is when a rectangular coil is placed in a magnetic field and current is passed through it, the coil rotates as a result of the forces acting on the coil.
What is the function of a magnet in an electric motor?
In electric motors, the magnet is used to generate rotation using electrical current passing through loops of wire. Many of the magnets we are most familiar with are considered permanent magnets.
