| 1. | Slip rings and brushes are used to conduct current to the rotor.
|
| 2. | The AC slip rings also allow the machine to act as an alternator.
|
| 3. | Accordingly, the field is mounted on the rotor and supplied through slip rings.
|
| 4. | During the start-up a typical rotor has 3 poles connected to the slip ring.
|
| 5. | While commutators are segmented, slip rings are continuous, and the terms are not interchangeable.
|
| 6. | Rotary transformers are often used instead of slip rings in high-speed or low-friction environments.
|
| 7. | Patina is also found on slip rings and commutators.
|
| 8. | Slip rings however inject commutator noise into the connection.
|
| 9. | Power is carried to the motors via slip ring brushes at the center and cables.
|
| 10. | In this instance, the rotating contacts are continuous rings, called slip rings, and no switching happens.
