Question

What is the functions of the following:
1. Carbon Brusher in dc motor
2.Split rings in dc motor
3.armature coil
4.Axle

Answer 1

a)-The brush transfer the electricity from outside of motor to spinning winding in the centre of the motor.
b)-When a current is allowed to flow through the coil by closing the switch the coil started rotating anti clockwise. it keeps the torque in the DC motor from reserving every time the coil moves through the plain perpendicular field to the magnetic field split ring at this time used to reserve current at this time.
c)-Armature is a power producing component of a machine. The armature role is twofold. The first carrey current and other one create Magnetic Flux.
d)-Axles are important parts of a vehicle. The axle keeps the wheels an equal distance from each other. 

Answer 2

A carbon brush is a critical part of a dc motor, which relies on the brush for the transmission of electrical current coming from the machine's rotating part. ... Aside from these functions, thecarbon brush keeps the surface of the slip ring, or the commutator, clean

To keep the torque on a DC motor from reversing every time the coil moves through the plane perpendicular to the magnetic field, a split-ring device called a commutator is used to reverse the current at that point


Armature reaction drop is the effect of a magnetic field on the distribution of the flux under main poles of a generator. Since an armature is wound with coils of wire, a magnetic field is set up in the armaturewhenever a current flows in the coils

a rod or spindle (either fixed or rotating) passing through the centre of a wheel or group of wheels....
