Our shipment of four motors arrived quickly and was well packed. We strapped one of the motors into our PFM/United UP 2-8-0 chassis and gave it a spin. The gearbox is an old United 40:1 that has not seen lube in way to many years and is bone dry. The suspension springs are also not yet installed so the gearbox can float up and down. We did not spare any expense in our mounting technique and used one of the few rubber bands we could find that was still pliable enough to hold together without breaking.
Using an old MRC power pack, the motor started the drivers at 3.5 volts but we then backed the voltage down to 2.5 volts and it kept the drivers spinning smoothly. About 7 volts established a rotation that would be about as high as anyone would want. Check out THIS VIDEO to see a brief demonstration of this motor in action.
It’s time we get back to the shops and dust off some of our projects!
