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.
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.
What will happen when running DC motor's field will open?
speed will increase
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.
What is the best dc motor to use when building a wind generator?
A brush-less DC motor (BLDC)
What is the brush used for in a DC motor?
To deliver the current to the rotating armature

Define the brush on a dc motor?
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.
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.
What causes a meter to read negative voltage across a DC motor?
The main cause for a meter to read negative voltage across a DC motor is a loose ground wire. The ground wire can be loose or may need to be cleaned.
What will happen if resistors are connected in DC motor?
The value and kind of resistors, connected in series or paralell, type of dc motor, what is the purpose, etc.
Can you reverse a DC permanent magnet brush motor?
Yes. Used on toy trains all the time.
What will happen if you will give ac supply to dc shunt motor?
it will not work.
What will happen when running DC motor's field will open?
speed will increase
