Split ring vs slip ring (1 Viewer)

[Drsoccerball]

Split ring = DC motors/generators
Slip ring = AC motors/ generators
Split ring reverses current direction every 180 degrees
slip ring ?

 

[Squar3root]

slip rings are used just to maintain contact between the motor and the stator iirc

slip rings are used just to maintain contact between the motor and the stator iirc

so no other job?

iirc, I don't think so they just connect the stator via the brushes to the rotating armature so it always maintains contact

Basically this.
Its just a way for the motor to receive current. Imagine if the two wires were attached at each end of the coil and the coil rotates.

What would happen? It would get tangled and won't spin.
The slip ring is just a way to overcome this problem.

The only other job is to ensure the connections to both the rotor and external circuit is not tangled

Slip rings (also called a slip-ring commutator) are only used in AC motors. They maintain electrical contact between the coil (which spins) and the brushes (which don't). The current in the coil needs to change direction for the coil to keep spinning; DC motors (with a constant supply voltage) achieve this with a split-ring commutator (the back-to-back C shapes), while AC motors achieve this with the alternating current changing direction 100 times per second (i.e. 50Hz or 50 full cycles per second). Slip rings don't need to change current direction (as a split-ring commutator does) because the current itself changes direction.

This question was answered ages ago................

But in the exam, to use physical terminology you should say 'allowing torque to constantly act in one direction' instead of 'keep spinning' on it's own.
