To deliver the current to the rotating armature
A brush-less DC motor (BLDC)
Yes. Used on toy trains all the time.
It stops working.
dc series motor is used for traction...
leave the brushes of the motor at the position where the induced voltage is zero
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.
leave the brushes of the motor at the position where the induced voltage is zero
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.
Yes it can and the otherway aroud a DC motor can be used as a dynamo
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.
yes dc motor is used in textile mills for presicion control.
