Parts of an electric motor
The Armature
–the structure attached to the centre piece that conducts theelectromagnetic flux reaction from the material to the field magnet.
Commutator
–a rotational switch curved around the centre piece or axle that switchesthe flow of current on the armature so the electromagnetic flux alternates as it makescontact with any one of the poles, to encourage repulsion in one direction only.
Brushes (Brush motors only)
–the best conductor used for rotating shafts wherecollecting electrons from a negative pole would be difficult using a solid conductor,whereas this one would bend, flex, and catch the commutator rings without stoppingthe rotation. However, the on and off contacts with the commutator promotes sparkingand then heat.
Axle
–Quite simply, the centre piece of the rotating shaft that turns on its axis.
Field Magnet
–The field magnet’s role is to encourage the rotation of the ar
maturewhere the electromagnetic impulses from the rotor decides the polarity and swapsthrough the commutator rings. Opposing polarities forces the magnets to push thearmature in one direction where the other pole would attract it and the cycle continuesvia a swap in polarity in the armature.
DC power supply
–In any electrical device that functions, this is extremely necessary. Asa matter of fact, without the power supply, this whole apparatus would be impossible. If there was no electrical energy, there would be no conversion to mechanical energy viathe electromagnetic effects
