You can't change the speed of an AC motor. The speed is governed by the
60 cycle current.

While the speed is determined by the frequency , it is easy to change the
speed. Just use an inverter such as:

Where I work we have 100's of them. They range from fractional horse power
to over 100 HP motors.

For small motors , it may cost as much or more than the motor.

For a table fan I use an x10 controler and do it remotely, I dont know
what type of motor the fan is but X10 might have something, but 1hp
draws alot of current

Most X10 modules do have limits on motor loads (as well as
incandescent lights), but outlet modules are often rated 15A
unconditional. If you don't want this installed in a wall, you can use
an electrical box with a cord. I'm currently doing that for holiday
lights (I use 4, on 4 different circuits).
