General Mach Discussion / Re: Looking for help with a spindle motor.

Well, I'm a happy camper.
I finally got time to give it some serious attention and it's now running just the way it should. Smooth and silent from 30 to 3000. I didn't try going over the design rpm but I'm sure it would.
Right out of the box the acceleration and deceleration seem quite acceptable. Once it actually is moving the spindle rather than just sitting on the floor it will be easier to tune it in.
The gory details: My first problem turned out to be the way I had been checking for a signal. My VOM has a frequency function and I had been using that. I finally realized the computer doesn't push a signal out, it offers it up. If the motor isn't accepting the signal, no sinking occurs and there is nothing for the VOM to read. Once I realized that, I went back and took a much closer look at my setup. I had plugged the motor into the wrong power supply so it was not getting adequate voltage. So much for doing things according to memory. Once it had the proper supply, things got turning and from then on, it was just a matter of sorting out the settings to get it spot on.
Now I finally feel comfortable with ordering the rest of the stuff needed to complete the installation.
