Answer / prakash d sdmit, ujire

Generator requires dc
current to energise its
magnetic field, soo
called excitation. And
dis dc current can b
obtained frm a
sepepate source also
v used to call dat as
exciter. Either dis may
b static or rotating.

It is a three inch fan and i want it to rotate to other direction .I've tried cutting the wire and reconnecting them inverse like black to white and white to black ,but it won't start rotating when i plug it in that way.And then it works again when i rejoin the wire to the way it is. I don't know what causing the problem.Is there anyone familiar with these small mortor?Any suggestion would be appreciated.Thanks!! http://i296.photobucket.com/albums/mm163/sasukebloodwheel/110527-105859.jpg
