slip ring

Patina is also found on slip rings and commutators.

During the start-up a typical rotor has 3 poles connected to the slip ring.

This can be accomplished using slip rings, wireless telemetry, or rotary transformers.

They use slip rings providing greatly extended brush life over a commutator.

The field current is supplied to the rotor windings by slip rings.

Only a small amount of field current must be transferred to the moving rotor, using slip rings.

Accordingly the field is mounted on the rotor and suppplied through slip rings.

Lift off the spout, which rests on a plastic slip ring at the base of the faucet body.

Which was a very good thing most of the the young apprentices would never know about slip rings.

Two slip rings had cracked, there were only the holders of the carbon brushes left, and the drive shaft looked doubtful.
