Yes a slip ring motor is there. There is a slip ring and a brush in the motor to add external resistance to the motor inorder to be able to control its speed.

When slip ring get negative charge in ac generator?
you apply dc voltage to slip rings in synchronous generators polarity will make no difference ( other than when it is first applied )
Why DC motors and DC generators are commonly known as DC machines?
because the dc motor will act as dc generator as same as dc generator acts as a dc motor .so it is called as dc machines.AnswerBecause generators and motors are machines, and operate on d.c.'A.C. machines' are generators, transformers, and motors which operate on a.c.
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
How do you change an ac motor to a DC motor?
Ac motor have slip ring, to remove the slip ring,connected to the commutator its a dc motor.
What is the purpose of using slip rings?
This is the standard answer for both split ring commutator and slip ring. A split ring commutator is to reverse the current direction through an armature every half turn A slip ring is to ensure that the current continue to flow to the external circuit Last bit of additional information. Carbon brush ensure that the slip ring are in contact with the circuit containing the external load *Note: Do not get confused with split ring commutator(d.c.generator) & slip ring(a.c. generator)
Slip rings and split rings?
Slip rings are used in AC while split rings are used in DC generators
How can you generate a DC?
U sohuld replace the slip-ring which it is in the AC generator to a commutator. It is a split-ring. Then u can produce DC generator.
How many types of DC motor?
Types of AC MotorsClassification Based On Principle Of Operation:(a) Synchronous Motors.1. Plain2. Super(b) Asynchronous Motors.1. Induction Motors:(a) Squirrel Cage(b) Slip-Ring (external resistance).2. Commutator Motors:(a) Series(b) Compensated(c) Shunt(d) Repulsion(e) Repulsion-start induction(f) Repulsion induction
What are the devices that make used of electromagnet?
AC/DC Motors, Generators etc. are the devices that make Used of electromagnets.
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).
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
What is type of DC and ac motors?
DC Motor :- SHUNT MOTOR, Series Motor, Compund Motor, ( mainly used in traction system only. as there performanace is very poor & DC supply is not available easily so there uses is less then AC motors,) AC Motor:- Induction Motor ( Slip ring Type, squrrile cage Induction motor) Syncronous Motor.
