Just look at the capacitor start motor connection in the diagram (there is other stuff shown, which you can ignore)
RE: Connection diagrams for 1phase 240volt capacitor start electric motors
There are 3 wires on my motor, red, white and blue. The red and blue are connected to a 4 terminal capacitor. The other 2 terminals on the capacitor go to a control board. I am trying to salvage a motor from a garage door opener.

What do you plan to do with that motor, since it has a very SHORT duty cycle!
White is common, red & blue are forward & reverse.
RE: Connection diagrams for 1phase 240volt capacitor start electric motors
I plan to use the motor on a small lathe and it will run for short periods of time at heavy loads (which still should not tax a 1/2 horse motor) and longer periods say 15 minutes with little or no load.
Will this be a problem?

If you look on the ABB website:
http://search.abb.com/library/ABBLibrary.asp?DocumentID=B5.0207&LanguageCode=en&DocumentPartID=&Action=Launch
- it's quite a large file, single phase motors are covered in section 7 (p191), there are some diagrams which may help, or they may not.
RE: Connection diagrams for 1phase 240volt capacitor start electric motors
The load is not the problem for that motor. It's the time and lack of cooling!
Typically, that motor has no fan on it to cool it so you will need to force air over it constantly!
Also, it is probably a permanent split capacitor motor with a capacitor that WILL explode if you run it for 15 minutes!
I think you would do best to purchase a standard Continuous Duty Capacitor Start motor for your application, since the motor you have was never designed to do the job you describe!
RE: Connection diagrams for 1phase 240volt capacitor start electric motors
Will heed the advice and get an appropriate motor.
thanks again.
