Re: [TCML] Phase Controller

[mddeming@xxxxxxx]

Hi Gary, All, 

True, it is all trial and error at this point. If there were enough examples of data on the Make, HP, Voltage, RPM, and Cap Size, and Variac size of all the existing, SUCCESSFULLY phase-controlled  SRSGs on the list, perhaps some sort of useful "cluster patterns" might emerge. I would be willing to do the compiling & analyzing if there is a convenient place on the list to host any results that may come from it. I realize it may be some time before enough data is collected to analyze. Please send any data off-list.

Matt D.

Trial and error is what we all use.  Way easier than pioneering a mathematical 
odel and solution.  Don't we all have a junk box full of motor caps? ;-)
Since the caps are used (energized) continuously, they need to be motor RUN 
aps, as opposed to motor START caps, which are only suitable for momentary 
peration.  
I suggest asking others using the same size and type of motor as you are, what 
hey use.  FWIW, with my small 3600RPM Teletype motor, I use a 40uF cap.

 Ok so using John Freau's design, whats the best way to get in the ball
 park on cap size? Can someone throw some supporting math out there
 instead of guessing? I would assume the type of cap used is important as
 well. Thanks all.
