Anybody know what the speed range is?? Be careful here.....I'm looking for motor speed "NOT" the spindle speed. If it is available, it will probably be in the owners manual.

Thanks.

Not listed in the manual.

I'll check tonight and post it. For some reason I'm thinking 0-1725 but I'll confirm it.
 
Thanks, guys.

From your comments, it is obvious that I still haven't asked exactly the correct question. Actually, I am interested in the motor's "controlled" speed range. Scott is certain;y correct in his suggestion that the lower end is zero; but what I am interested in is the motor speed when the spindle is at its low end published speed of 500 RPMs and its speed when the spindle is at its published high end speed of 3975 RPMs.

Frank: Have you looked at the JET web site lately? It sucks!!! The old site was pretty good.....lots of information and reasonably well organized. But they changed it recently and it is a disaster. I can't even get into the site anymore using the www.jettools.com address.....have to back door it through the www.wmhtooolgroup.com address. How bad is it, you ask......they no longer even have the manual pdfs for the JET Mini or the VS on the web site. I used to refer people to the site all of the time when they needed information that was in the manual. And the new 1220 manual.....no where to be found. I had to call customer service and they apologized for the omission and offered to email me one.

And on top of that, they now make you create an account and log in before you can look at the manuals. That is a real pain too as I only visit the site about once every few months and can never remember my login ID or password.
 
Forget the website, even the manual doesn't have it published.

Data from motor plate:

1800 RPM 162DC Volts @ 3 Amp

Mine was manufactured Nov 2006.

Zero RPM would be with switch off.
Switch on with variable resistor at lowest setting and belt on slow speed yields a spindle speed of 500 RPM - measuring pulley sizes top and bottom will yield motor RPM. Likewise, if motor is running at max of 1800 RPM and published hi speed spindle rpm is 3,900, measuring the pulleys should yield an advantage of 3900/1800 or 2.167. Variations can be many reasons such as old motor, bearing drag, different pulley size, etc.
 
Thanks, Jim. I will have to think about your comments a little. Seems like we might be able to calculate the low end motor speed without needing to know the pulley diameters. Of course we would have to "ASSUME" that the top spindle speed was achieved at the 1800 RPM motor speed and that may not be an accurate assumption.

FYI, I called JET today and chatted with several of the techies and no one there knew the answer to the speed question.
