Subject:Re: Leslie ramp down speed

George;

This is tricky at best. The rotor changes from fast to slow when the
smaller motor's shaft makes contact with the wheel between the two
motors--the rather abrupt change in speed is kinda inherent in the design.
You might try adjusting the position of the slow motor so that the contact
between the slow-motor shaft and the rubber tire is not as tight--that
might let the rotor spin down over a longer interval.

If you look at the way the slow motor is mounted, there are three screws
that go thru the motor and into the metal plate the motor is mounted on.
Two are on either side of the motor shaft, and the third is about an inch
back on one side of the motor. That's the one that adjusts the contact
between the motor shaft & the tire. There should be two nuts on that
screw, one one either side of the stack of thin metal plates. These two
nuts are used to adjust the motor position--just make sure they're nice &
tight when you're done, or the vibration will undo your adjustment in no
time at all.

If you have a copy of the owners manual/service manual for your Leslie,
it'll have a diagram of the motor that might clarify what I said above.
You can download copies of these manuals from Captain Foldback's website,
if you don't have one. It doesn't matter which manual, since the motor
assemblies for all the two-speed Leslies are essentially the same (except
for the recently-built ones, which have a single 2-speed DC motor, so I am
told).

Good luck!
