Answer Posted / p.prabhakar
Normally the motors works on the principle of Faraday's law and Lenz's law.There are two types of motors namely DC and AC motors.
In DC motors,the stationery part carring manetic flux is called field and the rotating part is called armature.when the current passes through the field and armature,a rotating driven force(called torque) is acting on the armature.Due to this the motor rotates.
Here the given supply is AC. Commutator is a device which converts AC to DC.In AC motor,commutator is not required and field is replaced by the name stator and armature by rotor.

I want to put this query to SENIOR & EXPERIENCED ELECTRICAL ENGINEERS. 1)I want to know about the control circuit diagrams for control panels. I found it difficult to understand. Is there ant booklet through which we can learn the circuit diagrams? 2)I want to learn about conduiting, laying cables, preparing cable schedules and various techniques which is the part of building infrastucture(construction field). I don't have any experience in this area. I have experience in control panels only. that's why i am not getting any opening in building infrastucture (construction field).Can I get the job in this field as Trainee Engineer?
