I intend to construct use a PIC to control the speed of a single phase <100W
AC motor but have not much idea how they are controled? Could it be
controled by Phase Control just like some light dimmers?
Any ideas?
Thanks

What kind of motor is it?
In some appliances, such as hair driers, there are permanent-magnet DC
motors with a full-wave rectifier. You can easily control them with PWM.
Induction motors (synchronous or otherwise), require variable frequency
AC power for speed control.
