The Ac motor is single phase with 220V, 6 A and 1horse power.Is it possible to use fan regulator to control this ac motor as well?
It strongly depends upon the type of AC motor. A synchronous motor would require a change in AC frequency to change its speed. (Or a change in its wiring configuration for the number of poles in the windings). A universal motor could use a dimmer to continuously control voltage and adjust its speed to any speed (within reason) .
