The slip ring is a device that allows electrical current to be transferred between a stationary conductor and a rotating conductor, typically in an electric motor or generator. It consists of a series of rings mounted on the shaft of the rotating component, and brushes that make contact with the rings to transfer the current.
On the other hand, a split ring is a type of conductor used in a DC machine (such as a DC motor or generator) to reverse the direction of the current flowing through it. It consists of a ring of conductive material that is split into two halves, with a gap between them. When the split ring is rotated, the direction of the current flowing through it changes as the gap passes over the brushes.
So, the main difference between slip rings and split rings is their function and the type of machine they are used in. Slip rings are used to transfer electrical current between stationary and rotating parts, while split rings are used to reverse the polarity of the current in a DC machine.

Key Differences Between Slip Ring and Split Ring
- Slip rings are used to transfer electrical energy between stationary and rotating parts of a machine, while split rings are used to reverse the polarity of the current in a DC machine.
- Slip rings are used in AC machines, while split rings are used in DC machines.
- Slip rings are typically continuous rings, while split rings are split into two or more parts.
- Slip rings collect power from a DC generator through brushes and transfer it to the coils of a motor, while split rings are used to change the polarity of the current.
- Slip rings are typically used in AC motors and generators to transfer electrical energy between the stationary and rotating parts of the machine. Split rings are used in DC motors and generators to reverse the direction of the current flowing through them.
- Slip rings are made of a conductive material, such as copper or gold, and are typically mounted on the shaft of a rotating component. Split rings are also made of a conductive material, such as copper, and are typically mounted on the rotor of a DC machine.
- Slip rings are often used in applications where it is necessary to transfer electrical energy over a long distance or where a high degree of electrical isolation is required. Split rings are used to reverse the polarity of the current in a DC machine, which is necessary for the proper operation of the machine.
- Slip rings are typically more expensive than split rings due to their more complex construction and the need for maintenance. Split rings are typically simpler in design and do not require as much maintenance.
- Slip rings are more prone to wear and damage due to the constant contact between the brushes and the rings. Split rings are generally more durable and have a longer lifespan.
What is Slip Ring?
Slip rings are commonly used in AC motors to transfer electrical energy between the stationary and rotating parts of the machine. The brushes are typically made of graphite or a similar conductive material, and they are placed on the outer surface of the slip ring to transfer the current.
The slip ring is connected to the coil of the motor, and as the motor rotates, the brushes maintain contact with the slip ring, allowing the electrical energy to be transferred between the stationary and rotating parts of the machine. Slip rings are available in a range of sizes and are also known by other names such as collector rings and rotary electrical rings.
What is split ring?
A split ring, also known as a commutator ring, is a device used in a DC machine (such as a DC motor or generator) to reverse the direction of the current flowing through it. It is typically made of copper or another conductive material and is split into two halves, with a gap between them.
When the split ring is rotated, the direction of the current flowing through it changes as the gap passes over the brushes. This allows the polarity of the current to be reversed, which is important for the proper operation of a DC machine. The split ring and brushes together are known as the commutator.
Split rings are commonly used in DC motors to convert the alternating current supplied to the motor into a pulsating direct current that is suitable for driving the motor. They are an essential component of DC motors, as they allow the current to be properly directed through the windings of the motor, helping to ensure that it operates smoothly and efficiently.
