The stator coil is exactly the same as a 3 phase induction motor. The difference being the rotar which has 3 phase wiring in star point or delta connection and also has the sliprings connected to the wiring of the rotor. Brushes are use for the contact between the surpply and the rotor. By controling the current we can control the torgue and speed of the motor. This is done with resistance. Resistance can be greated by means of a resistance bank, liquid resistance or a variable resistance. The basic Idee is: The higher the resistance, low starting current, high torque, high % slip. Motor runs slowly
Low resistance , Higher starting current, lower torgue, lower % slip Motor runs faster.
Thus by varing the rotor resistance the motor can be adapted for a spesific load.
The motor Are mainly used for Overhead cranes, Elevators in buldings, Pumps under pressure and large fans

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 are the reasons of sparking on the slip ring of a slip ring motor?
ring is dirty or brushes arent seated
How do you calculate resistance box for slip ring motor?
how to calculate resistance box for slipring motors
What is the slip of synchronous motor?
A synchronous motor runs at synchronous speed, so there is no slip, or zero slip.
How do you slipring motor is convert to inducton motor?
With a synchronous motor shorting the slip-rings together should make it work as an induction motor although perhaps not to an optimal degree.
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.
Do dc motors and generators has slip ring if so for what?
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.

What is the basic difference between carbon brush of AC slip ring motor and carbon brush of Direct current commutator motor?
The only difference between slip rings and commutator is that commutator can change the frequency where as the slip rings can not do it.
