Let's talk Servo motors

Mike, are you saying that your tripping the main breaker in your shop if you turn on your clutch motor while the ac is running?

DC servo motors don't load up and draw more current at start up like ac clutch motors do, so you shouldn't have the breaker popping issue. I'm on the road for the next week otherwise I'd throw an amp clamp on my servo and my clutch motors and give you real current draw numbers at startup and wide open.

Low voltage raises current (amps), which makes heat that trips your breakers. If you have any electrician friends you could have them wire in a buck boost transformer in front of your power panel to give you more voltage and more headroom on your breaker.

not the main breaker  but the ac and Maine plug and a ligbt I'd on one breaker

Do you have an extension cord on your sewing machine or ac unit?

Standard clutch motors require the most power at startup cor sure.  I have no idea the comparison between clutch startup and an active running servo at all.

no just wall
plug

Bobbin,

I'm surprised the Relaible motor you have is noisy.  Usually they are a quiet running motor, really.  I wonder if the motor pulley is not getting hung up, or it could be defective. 

I'll send an email again and make a recommendation, if I may.

Gregg, I've had 2 e-mails bounced back to me... please tell me my e-mail addy isn't "spam".  OUCH, you are cruel, man!
