Hello,
Lathe spindle speed control: electronic vs mechanical
Could you please look at the diagram below as a common generalised gearing mechanism for, say, driving a lathe spindle.
Now, comparing this with an
AC motor speed controllers like the following:
Is it possible to do away with the mechanical cone pulley system with this type of electronic speed controller?
Judging by many examples of lathes for sale online it appears the answer may be yes. For example this one appears to be directly driving the spindle without gearing:
Please note: I am not asking about this particular circuit as such. My question is a general one
