I got a mini project to design the speed control of 1 phase induction motor using TRIAC. I googled a lot for it but all in vain. I need the specifications of the components to be used and the circuit diagram. Kindly guide me how to proceed.
Specify the type of motor, speed range desired and the application.
A small 1/20 hp shaded pole motor driving a light load like a fan would be a candidate for a simple triac control.
A 1 hp motor driving a large fan or heavy load would be a candidate for a variable frequency drive or a mechanical speed adjuster
Big difference in complexity. There might be some specialized IC's to make a VFD simple since there is a lot of call for it. When going to a VFD for speed control, there's a lot of incentive to use three phase because capacitor run/start motors don't take kindly to different frequencies and 3 ph does.

Thanks everybody for the help. Actually the project has been assigned to me by a very strict instructor of mine, so I can't tell her that its trivial or very hard etc etc. Also nothing else has been specified. As far as I understand I have to use TRIACs to design a variable voltage/frequency source, but thats the only thing I know. Can anyone suggest me a site or something from where I can get atleast a circuit diagram or the components to be used to design such a circuit.
Thanks for the suggestion Rich but let me tell you that I wasn't demanding to be spoon fed. I was just asking for the right place to start with. Morever I had googled a lot before asking the question in this forum.
