Those are simple "dimmer" style controls. *They are *not* for
induction motors.

It says Shaded Pole motors, which ARE induction motors. *Unless you can
show me a shaded pole motor that is not an induction motor? *I'd love to
see it!
You won't find a whole house fan that uses a shaded pole motor, but go
ahead and smoke your fan.
I said those dimmers were indeed for shaded pole motors, someone
disagreed, I don't really care who it was. *But the fact is that the
speed controls I suggested can be used on shaded pole motors.


I didn't see anyone saying that they weren't for shaded pole motors (or
universal motors, for that matter), only to *not* use them on induction
motors.


Oh, OK. *Now show me a shaded pole motor that isn't an induction motor.

Hell, I don't even have a whole house fan, so I don't suppose there is
much chance of me smoking my fan. *Unless it was made of hemp. *No not
really.


The thread is about controlling the speed of whole house fans, idiot.


So I have to own one to reply? *Show me a shaded pole motor that isn't
an induction motor.


Idiot. Not all induction motors are shaded pole. Shaded pole motors
are *NOT* used for whole house fans.
