A slip ring motor contains a slip ring, which is a mechanical device that transmits power and electrical signals from a stationary to a rotating structure. They are commonly found in engines used in cable reels, wind turbines, packaging machinery and radio telescopes.

What will happen if we slip rings are used in motors intead of commutator?

If slip rings are used, a dc field current fed to the rotor through the slip rings causes a magnetic field that rotates with the rotor. This is used in synchronous motors and also in alternators in cars and power plants. In a car alternator the dc current supplied to the rotor is used to control the votage generated in the stator, which is connected through diodes directly to the battery.


How many Slip rings in synchronous motor?

If the synchronous motor is single phase then there are two slip rings & if this motor is three phase so the slip rings are three in number. Correction; I have never seen a single phase synchronous motor. It would cost more that it was worth. A synchronous motor has a separately excited field. If the excitation comes from a stationary DC source it has 2 slip (collector) rings. A brushless induction motor has no slip rings because the exciter armature rotates and so do the rectifiers. A permanent magnet motor, used with variable frequency drives, is another type of synchronous motor that has no slip rings. A three phase motor with 3 slip rings is a Wound Rotor motor. Wound rotor motors are variable speed motors that were used for such applications as bridges and cranes before variable speed drives.


When the slip ring induction motor is preferred?

larger synchronous motors start with a squirrel cage and run when dc is applied thru the slip rings small motors can have magnets in the rotor these can accelerate from rest to synchronous speed in a few seconds


Slip rings and split rings?

Slip rings are used in AC while split rings are used in DC generators


What is the need for slip rings?

Slip rings offer a means of connecting a rotating winding to an external circuit. Slip rings are used when an a.c. output is desired.


What are slip ring motors?

slip ring motors are one in which the rotor is connected to the slip ring directly in which the slip ring also connected with the shaft so that it rotates with the rotor simultaneously..


Where can I obtain electrical slip rings online?

Electrical slip rings can be purchased from a number of online sources. Some of these stores, include Mercotac (www.mercotac.com) and Lucas Alternator slip rings (at www.tradekey.com).


What is the differences between the slip and split rings?

Split rings are in AC generators ( alternating current) while slip rings are in DC current (direct current).


Why are the slip rings needed in dc motor?

Slip rings are needed to connect a rotating armature to external fixed circuits.


In the generation of electricity commutator would be used on an alternating current generator and slip rings would be used on a direct current generator?

No. Just the opposite. An AC alternator uses slip rings, a DC generator uses a commutator. Most modern auto alternators are in fact AC alternators that rectify the AC output to DC using a diode bridge.


Where can I purchase electrical slip rings?

Electrical slip rings are available from Sibley.com and Mercotac.com. You can also find them at local electrical supply stores.


What the main different between shunt motor and induction motor and AC motors?

induction motor is AC motor also synchronic motors are AC motors but second one has not slip but first one has slip . shut motor is DC motor
