I would recommend looking at “world wide electric” for the gear reducers.

http://www.worldwideelectric.net/product-category/gear-reducers/inline-helical-gear-reducers/

Simply select the speed/torque you want, and then you will see the motor requirements.

Inline helical gear reducers should be a bit more robust and cheaper than a worm gear or helical bevel reducer, but takes up more space.

You can then source a C-face motor to suit your needs. Single phase motors above 2HP are expensive and sometimes hard to find. Keep in mind that 3-phase motors are quite a bit cheaper than single phase motors, and often times you can use a VFD + 3 phase to convert single phase to 3 phase. With a VFD you have the ability to do all your controls on the drive, so no additional switches/reversing contactors/etc are required, and you can adjust speed to your liking.

If I was to go back and do mine over again, I would have used a slower speed (higher torque) reducer and used the VFD to speed it up if I wanted more speed. For my shredder I thought that 80 RPM was a little fast, so I’m going to look at getting a different reducer to run more like 50-60 RPM.

Motor with a reducer will be easier to find. the people who hve built the shredder recommend a 2HP Triphasic motor reduced to 70-100 rpm
