The electromechanical device that is used to transfer the electrical energy (in the form of current) across the moving interfaces or device (like as a rotor) is called as a 'Slip Ring'. Kids have a Hot Wheels track. However, a slip ring does not convert the ac to dc or dc to ac but the split ring does. The split ring is a movable device used for reversing the polarity of the current. A commutator consists of split rings two rings with some space between them and brushes attached to the circuit. a split ring commutator changes the current direction every half turn Once the conducting brushes reconnect with the commutator after a half turn: current flows in the opposite direction. Without a split ring commutator, the same process would then take place in the opposite direction, causing the motor to repeatedly rotate 180 degrees. The split ring uses in DC motor for getting the pulsating input voltage. Split Ring Commutator. Log in. It is called a mechanical rectifier in generator and an inverter in motor. The slip ring is a closed ring (continuous), whereas the split ring is divided into two parts or more. They are used in DC electric motors to maintain a steady current to the windings which should produce a constant torque since the current direction in a coil is reversed after each half turn. A slip ring can be used in any electromechanical system that requires rotation while transmitting power or signals. A slip-ring commutator simply maintains a connection between the moving rotor and the stationary stator, whereas a split-ring makes the current change direction every half-rotation. When a dc motor shaft comes into contact with a split ring, the split ring reverses the current to maintain the shaft torque in a magnetic field. It has two halves, each connected to the power supply, completing the coil circuit. They are attached to the commutators, and the commutators are attached to the wire loop.
