Fanuc servo shaft taper angle?

[Jonne]

Hello again!

Anyone knows what is taper angle on this Fanuc servo:


I can measure it with my Bridgeport, but if anyone know...

I believe that all Fanuc motors with a tapered shaft have a taper of 1:10.

I'm not sure if that's 1(diameter) to 10(length) or 1(radius) to 10(length), but a simple measurement will reveal this. The only diagram I could find online seemed to imply it was 1(radius) to 10(length), but the diagram was not properly dimensioned, so there is some doubt about this.

I do not know if it is 1:10. But 1:10 means 1mm increase in 10 mm length.

My i series motors are 1 dia. : 10 length
