Or if you have a 2-speed motor like me, the speeds are as follows:
(UK 50Hz)

Low range: 67-115-180-275 / 134-230-360-550
High range: 550-920-1500-2300 / 1100-1840-3000-4600

Or if you have a VFD the range is 3 RPM to 4000 or so in 8 steps..

Thanks X39 - exactly what I was looking for.

So the gear reduction is somewhere around 8.3:1? If I do the numbers, I get anywhere from 8.25 to 8.333.....

Anybody know the actual gear ratio?
