i want to use a 1µF capacitor to start the motor with a TRIAC to control the speed. Does anyone have the TRIAC circuit :?:

Do you want two separate circuits for starting and speed controlling?

This article gives a few circuits with application notes.

And here is project with PCB layout, too.

Look starting of motor has nothing to do with Speed control, as first motor has to start and go running then it will be possible to control speed. Here is a circuit to give you bit clarification of this:

And if you want circuit notes, visit:
AC Motor Speed Controller

Any further help, if needed, is welcomed.
