You can't use a rheostat or autotransformer to slow the motor down because you are only changing the voltage. The frequency determines idle speed and the voltage applied to the motor affects only the torque when operating against the load. If you decrease input voltage enough to slow the motor down, you'll burn it up.
Now a DC motor is a whole 'nother animal.Equipped with red and blue... and red and green!
