I need a 1/4 hp motor that can be controlled at constant speeds of between about 100 rpm and 5000 rpm. A stepper motor, and controller, is probably needed for holding a given set speed within about a 1% variation for periods of weeks to months.
I know nothing about these things; I need suggestions on manufacturers and suppliers. Any help would be appreciated a lot. If you can help, please write to me at snipped-for-privacy@yahoo.com.
Much thanks,
Bob
