Stator of three phase induction motor creates Rotating
Magnetic field.But why not Transformer?
Answer Posted / martin
A transformer is like a single phase stator. It has a
single oscillating magnetic field( flux ). You need an
emerging magnetic field to push an existing field into
motion. Hence, a two phase stator is the minimum required
to create a moving(rotating) magnetic field of flux. Flux
generated by the first phase gets pushed out of the way by
the succeeding phase flux (180deg away). The flux is beng
pushed and so moves. Its a field of flux being pushed
sideways by the ascendency of emerging flux. Inside the
circular stator it forms a flux whirlpool.
