Inexpensive gear head source?

[Guanton75]

Can anyone offer a good inexpensive source for gear heads for a NEMA 23 motor? I need a ratio of around 20:1 with e final output torque around 32 in-lb and 150 rpm. Back drivable is need too. Of course, a good cheap 75 watt 3-phase motor would be helpful too but the Pittman motors seem ok. Quantity is around 300/year.

Thanks,
Seth

Check the Grainger or Minarik catalogs for gearmotors large and small at the quantities you need. (About 70 of my designs are in both.)
