    I have a 10,000 lb load frame. It came with a Dayton motor 4Z382A. 90V DCPM 61 RPM 113 in-lb, 1/8 hp, 30:1 gear ratio. This motor would not run slow enough. So I replaced it with a 4Z383A. 90V DCPM 31 RPM, 244 in-lb, 1/8 hp, 57.7:1 gear ratio But with this motor I can not run fast enough and It
    stalls out at the very low end. My frame translates motion using a Acme thread shaft. I would like to have a speed as low as 0.0001"/min (but I can live with 0.001 "/min) and as fast as 0.05 "/min or greater. My top end is only 0.04 "/min so it is very close. It uses a rheostat type knob with
    about 10 revolutions of travel to adjust the speed.

    Motor Details here: http://www.grainger.com/Grainger/wwg/viewCatalogPDF.shtml?browserCompatable=true&adobeCompatable=true&CatPage=183


    How can I get a larger rpm range and still maintain the torque to keep from stalling?
    It is belt driven so I could change pulley size.
    Thanks in advance.
