Definition

Noun: A slip ring is a specialized electromechanical device. It consists of a conductive metal ring mounted on a rotating part of a machine. Its primary function is to allow the transfer of electrical power or signals from a stationary structure to a rotating component, maintaining a continuous connection via sliding contacts called brushes.

Usage

The term slip ring is used to describe the specific component that enables electrical connectivity in rotating assemblies. It is a technical term common in engineering, industrial machinery, and electromechanical design.

Examples

• The motor's slip ring was worn and needed replacement to restore proper electrical contact.
• To transmit data from the rotating radar dish, engineers installed a high-quality slip ring.
• The design incorporates a slip ring to supply power to the lights on the revolving restaurant floor.

Advanced Usage

• Slip ring assembly: Refers to the complete unit, often including multiple rings, insulation, and housing.
  • The generator's slip ring assembly failed, causing a complete shutdown.
• Slip ring commutator: While distinct in function (commutators reverse current in DC motors), the terms are sometimes discussed together in the context of rotating electrical interfaces.

Variants and Related Words

• Collector ring: Another term for a slip ring, often used interchangeably.
• Rotary electrical interface: A more general, descriptive term for the function a slip ring provides.
• Brush: The stationary conductive contact (often made of carbon or metal) that presses against the rotating slip ring to transfer current.

Synonyms

• Rotary connector
• Electrical swivel
• Collector ring

Related Phrases

• Slip ring induction motor: A type of AC motor where the rotor winding is connected to external resistance through slip rings, allowing for controlled starting.
  • The heavy-duty crane uses a slip ring induction motor for smooth acceleration.

Noun

1. connection consisting of a metal ring on a rotating part of a machine; provides a continuous electrical connection through brushes on stationary contacts
