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.

Please clarify, 1. Is it required to lay two runs of GI wire along with Armoured LT cable if it is laid between one big mains (63Amps TPN SDF) to small main (32A TPN SDF) with proper glanding termination? 2. If the armoured cable with proper glanding is laid from DB to CNC machine, is it required to run two runs of body earthing to the Machine from DB? 3.If the armoured cable with proper glanding is laid from Substation to Hangar, distance is approx. 100 mtrs, is it required to do earthing at shop area though the primary termination at substation is earthed through gland.
