The document summarizes the main parts of an electric motor construction. The two major parts are the stator, which houses the field winding, and the rotor, which is the rotating part. Other key parts include the yoke, which forms a protective covering; poles made of core and pole shoes that produce magnetic flux; field windings wound on pole shoes to form an electromagnet; an armature core with windings to induce current; a commutator that collects alternating current and converts it to direct current; and brushes that make contact with the commutator to deliver current to the stationary circuit.

1. Main construction diagram

3. Main
partsThe two major parts required for construction :
1. Stator
That houses the field winding
1. Rotor
Rotating part that rotates in magnetic field

5. Other
parts□ Eye bolt
□ Yoke
□ Poles(pole core and pole shoes)
□ Field winding
□ Armature core
□ Armature winding
□ Commutator
□ Brushes
□ End covers
□ Bearings
□ Shaft
□ Terminal box
□ Interpoles

6. Yoke
□ Its main function is to
form a protective
covering over the inner
sophisticated parts of
the motor and carries
the flux produced by
the poles.
□ Made up of cast iron or
steel.

7. Pole
s□ The magnetic poles are
structures fitted onto the inner
wall of the yoke with screws.
□ The construction of magnetic
poles basically comprises of
two parts namely, the
core and the pole
stacked together
hydraulic pressure and
pole
shoe
under
then
attached to the yoke.

8. Field winding
□ Made with field coils
(copper wire) wound
over the slots of the
pole shoes
□ The field windings
basically form an
thatelectromagnet,
produces field flux

9. Armature
□ The armature core are
provided with slots to
which the armature
windings made with
several turns of copper
wire distributed
uniformly over the
entire periphery of the
core.

11. Commutat
or□ It is a cylindrical structure
made up of copper segments
stacked together, but
insulated from each other by
mica.
□ Collects the current from the
armature conductors
alternating current
in the armature
into unidirectional
□ Converts
induced
circuit
current.

12. Brush
es□ Made with carbon or
graphite structures,
making sliding contact
over the rotating
commutator.
□ Collects the current
from commutator and
make it available to the
stationary ckt.
