why we can choose induction machine in wind mill? why can`t use synchronous machine?..

Answer / manish meena

The reason is that syn. motor is mainly designed for
constant speed operation,as wind is not blowing with
constant speed,so we can not use syn motor.

Answer / just some guy

It all depends on the connection to the grid. Synchronous
machines can be used as well, but they have to be decoupled
by power electronics to adapt the frequencies of the wind
voltage and current to the grid voltage. Induction machines
are very reliable and there is less maintenance expected. So
the answer would be: We could use the syn. machine, but the
distribution system would have to be built on different
considerations, which might be more costly.

Answer / sameer

first we know that
synchronous motor is
not self starting
motor so it reqired dc
exitation to the rotor
and this problem is
not in i.m so if we
consider to connect
motor to wind mill
than we need to power
produce not the use
otherwise it decrase
efficiency and also
synchronous motor is
complicated
construction then i.m
so
