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

In addition, where signals and power need to pass to the model, some form of slip ring arrangement is required.

Neither brushes nor slip rings are used, which reduces the number of wearing parts.

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

Slip rings and brushes are used to conduct current to the rotor.

Power is carried to the motors via slip ring brushes at the center and cables.

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

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

Patina is also found on slip rings and commutators.

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

The slip ring device is also limited by temperature, as mercury solidifies at approximately -40 C.

Ordinarily, slip rings and brushes connect the rotor to external power.

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.

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

A DC motor is usually supplied through slip ring commutator as described above.

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

The slip ring assembly requires maintenance and compromises system reliability, cost and efficiency.

The electrical contacts are usually made through a "brush" or slip ring, which results in large losses at the low voltages generated.

Slip rings are made in various sizes; one device made for theatrical stage lighting had 100 conductors.

In this instance, the rotating contacts are continuous rings, called slip rings, and no switching happens.

A slip ring (in electrical engineering terms) is a method of making an electrical connection through a rotating assembly.

A slip ring is an electrical connector designed to carry current or signals from a stationary wire into a rotating device.

The magnetic field on the rotor is either generated by current delivered through slip rings or by a permanent magnet.

A slip ring is an electromechanical device that allows the transmission of power and electrical signals from a stationary to a rotating structure.
