The brush is actually a piece of carbon placed on the rotating commutator of the motor. it will be in pairs. Since the armature shaft rotates but gets the continuity through these brushes.

What is the best dc motor to use when building a wind generator?
A brush-less DC motor (BLDC)
What will happen if you loose a brush in a dc motor?
It stops working.
What is the brush used for in a DC motor?
To deliver the current to the rotating armature
How do you locate the neutral brush position in a dc motor?
leave the brushes of the motor at the position where the induced voltage is zero
what are a few of the disadvantages to a brush-less motor controller?
The brush-less motor controller has a smaller output current than one DC motor. The brushless also has less of a output voltage. The maximum output voltage is 50V, where a regular DC motor would have a maximum of atleast 60V.
Syllabus for 1st semester Anna university trichy?
define dc motor
Explain how to locate the neutral brush position in a dc motor?
leave the brushes of the motor at the position where the induced voltage is zero
How rotar rotates of DC motor?
The rotor in a DC motor rotates because the magnetic field in either the rotor or the stator is constantly changing. If it is a brush type DC motor, then the rotor field changes as the rotor moves to a new position on the commutator. If it is a brush-less type DC motor, then there is some circuitry associated with the stator that changes the stator field.
Can you reverse a DC permanent magnet brush motor?
Yes. Used on toy trains all the time.
What causes the overheating of commutator in dc motor?
brush friction, poor ventillation, excessive sparking caused by high voltage
What is meant by bressless DC motor?
I've not heard the term "bressless" - I think you mean "Brushless" - which is a DC Motor that does not use the usual commutator/brush arrangement. For a great answer to this question, see the Wikipedia article in the related links section.
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.
