AC Drill Speed Controller

Due to high RPM of drilling machine,sometimes drill bit will be damaged. To avoid this problem I made this speed controller. We can use this for any type of AC motor's, saw's, fan etc... and also as light intensity controller.

Step 1: Parts Needed

• Gang box
• AC socket
• AC wire

• Voltage Regulator Dimming Module

Step 2: Assembling

• Drill two holes in the gang box. One for AC wire and another for dimmer controller.
• Insert the dimmer in one of the hole and fix it.
• Fix the AC socket.

Step 3: Connections

Wire according to the picture above

Step 4: Finally

Make a Label and attach it.. It's finished.

I don't mean to be unpleasant, I just feel frustrated:
it is not actually a speed controller, it's an electrical power controller (I have it).
If you choke your drill or whatever motor it will slow down.
A speed controller would try to keep speed constant.
EVERYBODY on the 'net makes this mistake.

diagram and photo is different of the wairing please check...

Great instruction. I ordered the same,and it is working well. however it is making a noisy sound,when I decreased the power, like ziiiii. When it is on full power,that noise is gone.

Can I please tell me if yours is making that noise? It is a bit scary.

It 's a good idea for angle grinding machine.

omg... yet another buy from shop, read manual, install as per instructions.... instructable. Did you re-type it all by your little self? or did you just cut and paste the manual that came with it?

I bought it from china... No manual is provided with it.

It did not work.

I like the idea, but I would use this sparingly. Running an electric motor at low voltage can damage the motor. The motor will run hot and wear out quicker.

Dremel used to offer a variable speed controller box you could plug your Dremel (or other tools) into. It kept the voltage constant at all speeds so your tools were safe. I believe it modified the frequency instead of the voltage. There's probably something similar out there that would do the job without risking your tools.

I like your work.

Thank you

These are indeed very handy to have. I would only make one suggestion though; to add a fuse for circuit protection, this controller may be used in several different applications so a safety device would make sense.

Thank you for your suggestion

Very cool!

With controller like this it would be pretty easy to make a drill lathe.

Yes. Thank you for your comment
