RE: speed of the motor
Separate topic. Quite a remarkable products at:
http://www.magnadrive.com/
The product that they call and "adjustable speed drive" takes the place of the coupling and allows variable (externally-controllable) slip between the motor and the load (pump, fan etc). Take a look at their video.
RE: speed of the motor
It is normal in a motor of 220Vac that must apply 150Vac or less depends it the motor and the resistant pair.
The reduction is with a autotransformer.
