Answer Posted / vikas_04el
SIMPLIFICATION MOTOR PRINCIPLE :- whenever current carring
conductor place in the magnetic field, the electric flux is
cut by it.Now if rotor ckt is short ckted the then current
is flowing.
Now doe to that force (revolving force) occure in the
rotor. And hence motor is rotates.
WHERE AS IN CASE OF TRASFORMER THERE ARE TWO WNDING
1. PRIMARY WNDIG
2. SECONDARY WINDING
WHICH IS BOTH MOUNTED IN SAME CORE(WHICH IS STATIONARY)
NOW IF WE SUPPLY THE PRIMARY WNDING THE EMF IS INDUCED IN
THE SECONDARY WINDING BY ELECTROMAGNETIC EFFECT. THIS EMF
INDUCED BY MUTUALLY INDUCTION PRINCIPLE
SO THERE IS NO RELATIVE EFFECT OCCURE.
THATS WHY MOTOR ROTOR IS ROTATE WHERE AS TRANSFORMER IS NOT
ROTATE
