Slipring in AC Motor

Slip rings transport power, electrical signals, or data between fixed and revolving components. They are also known as electric swivels, rotary electrical couplings, and collector rings. A slip ring’s design will depend on how it will be used; for example, a slip ring used to transmit data has to have a greater bandwidth and better EMI (electromagnetic interference) mitigation than one used to transfer power. However, slip rings generally consist of a spinning ring and fixed brushes. Fabco Universal is the carbon brush manufacturer in Delhi NCR.It would be conceivable to employ spools with enough cable length and rotating speed to accommodate the needed revolutions if the rotation of one component requires a fixed number of them, however, cable management in this arrangement can be highly challenging. However, it is sometimes impractical or unreliable to use cables to carry signals between rotating and stationary components if one of the components spins continually. You might have observed that a commutator and a slip ring have extremely similar structures and operations. Even though the two have some similarities, slip rings and commutators differ significantly. Physically speaking, a commutator is segmented, whereas a slip ring is a continuous ring. Slip rings serve as a continuous conduit for the transmission of power, signals, or data. They specifically convey resistance to the rotor windings in AC motors.Contrarily, commutators are employed in DC motors to switch the polarity of the current flowing through the armature windings. Each armature coil’s ends are joined to 180-degree-apart commutator bars. Brushes deliver current to opposing commutator segments and, thus, opposing armature coils when the armature spins.
