Re: [TCML] Variable RSG

[bartb <bartb@xxxxxxxxxxxxxxxx>]

Yes, I saw a picture at harbor freight website. It had a "full" and 
"variable" switch with center off position. So, one could get the motor 
up to full speed then switch to "var" and decrease the speed of the 
motor with the dial. A high rpm motor is needed for access to the higher 
speeds since it would be from 0 to full speed. I suspect it's a clipping 
circuit removing portions of the waveform for the variation rather than 
a variable voltage (must be something like that to be in such a small 
controller). I'll have to pick one up someday and check it out.
