how do I search for/find the motor or gear reducer that I need for root washer?

Topic Type: 

We have everything seemingly ready for our washer except the motor. We have a 1/2 hp 1725 rpm motor, bit no gear reducer, and I'm really stumped on how to search for and find one that will be compatible with our motor (image attached). Likewise, I don't know what search terms to use to find a pre-assembled motor+gear reducer, and to know that I am purchasing what I need.

The info on this page is already giving me more than I had to go on before, but I'm a total motor novice. Any advice?

I likewise don't know anything about gear reducers but this seems to be similar to the one Versaland is referring to.

Chris Callahan, UVM ag engineer has some additional info to add: 


The motor they have is fine, there is a prior thread on the topic.  ½ HP 1725 RPM.  Need to check whether the face is 56C or not.  It makes connecting to the gear reducer easier.


For gear reducers, they should search “56C 40:1 gear reducer”

The 56C face is a standard 4 bolt face that makes attaching the gear reducer easier and more stable.  Doesn’t look like the motor they have has that face."

I think this may be the previous thread he's referring to.

I was looking in on a discussion on HomesteadingToday a while back, and a tinkerer addressed the geared-reduction issue. This guy said he'd come up with a solution applicable to a number of projects: kitchen mixer motors/gear sets. Remember there are both the common rather puny ones for home kitchens, and heavier-duty ones made for commercial kitchens and even industry.  Advantages: variable speed controls, & solid gear reduction - and the guy said, also, easy to mount and use.  The guy said he got some sort of a "Mix Master'" from eBay for $25.

Remember, these are motors and reduction gears that are joined together - and that could be an advantage.  Otherwise, you'd be working out the specifics of mounting.  I must say I was shocked to see brand new gear-reduction boxes selling in the $500-1000 range.

Back to the HT guy and what he recommended: besides eBay, he recommended restaurant-supply providers (new & used equipment, often) - industrial cooking supply.

Another thing he mentioned that might possibly be adapted is an electric drill (think of h.d. half-inch-drive D-handled drills with lots of power, not cordless compact ones).  Again, will supply you with geared reducer sets/housings.  You'd have to work out the mounting.

Good luck.
