how to reduce RPM of AC motor

i have an AC motor of washine machine dryer.. i want to control it using arduino but its RPM is too fast (1000RPM) and i want to reduce it to 100RPM.. what should i do?

Turn it on for 6 seconds, and off for 54 seconds.

Or use 1:10 gearing/belt, as suggested in your other thread. Leo..

i did try doing that in my codes not working can i use voltage regulator?

We don't know what type of AC motor you're talking about (there are many), but you can't easily change the RPM of an AC motor. Post an image of the motor. Leo..

my problem with the RPM is solve by using belt and pulley.. however my problem now is the torque is too weak.. how can i increase or upgrade it

If you reduce the speed with a pulley syste, the torque is increased. What are you driving? It sounds like your motor is not powerful enough. Tom.. :)

Without full details of your hardware we can only guess.

What motor?

Show us a photo of the pulley system.

What torque do you need?
