Electric Motor

A universal motor is a single-phase series motor.

Universal motor is able to run on either ac or dc .

The field windings of a series motors are connected in series with the armature

windings.


Construction of a universal motor is similar to the construction of a DC series motor.

The whole magnetic path (armature, stator field circuit etc) is laminated.

The flow of current is in one direction in all the conductors on one side of the

armature, and in the opposite direction in all the conductors on the opposite side

of the armature.

CONCLUSION


We know that In the coming years new technologies are

created and everything will be supervisory control.

Automation system provide excellent services in installation and

commissioning for various industrial manufacturing, production,

power generation, fabrication, chemical, Petrochemical, and

refining processes and day by day it is getting wider.

The increasing capacity of microcontrollers continues to offer new

opportunities for product differentiation in real-time control

systems.
