"Susie,
See 4600-008, 010, 011 & 050 for the gears used.
It comes with instructions on gear selection but you get higher ratios by adding progressively more stages and having the longer output shaft in the middle or the outside mouting holes. One stage gives you 4:1, each additional stage gives another 4:1 reduction. Just remember that two 4:1 stages gives 16:1, 3 stages 64:1 etc.."

"Do you have the dimensions for the gears? And which combinations provide each diffferent ratio?
Ta"
– Susie
26/04/2012, 21:05
"Theo,
Sorry but that figure is not quoted by the manufacturer. However, we would assume 15mm as the output shaft is in the middle row (from the photo) and that the overall height is 30mm."
– Admin
26/04/2012, 14:59
"Hi, what's the distance vertically from the base of the unit to the output shaft axis?
Many thanks in advance!"
– Theo
29/10/2011, 19:45
"Ken,
We have added a 'Details' tab which details the motor performance.
The shaft is 3mm diameter."

"Hi,
What's the diamter of the shaft of the gearbox?
Thanks!"

"Hi, what is the full load current of this motor?
Thanks"
