I know this is an old thread but you may want to consider the following with respect to BLDC motors and controllers. When you use a cheaper motor control with these motors, they often use a sensorless control mode which detects rotor position by detecting the back EMF in the unpowered coil...

I wonder if the corrugated plastic that's used in wiring looms might do the job? http://www.cableorganizer.com/wire-loom/colored.html Nitrous

I have a compact 5 and a Craftex 7x that I'm looking at putting magnetic scales on. I have the DigMAG by iGaging, but I am interested in finding a cheap, Magnetic Scale source. I used to think that rotary encoders have no value in Lathe work but I did a little research looking into it. There...

I believe you're talking about sine error which is a fact regardless of what linear scale you use. But the quoted specs for iGaging are not great, especially in the context of a lathe. Description (from the iGaging site) Accuracy: ±0.002” per 6inch Repeatability: 0.001” Battery: 3V...

The point about back lash in (most) rotary encoders is true, but I understand that this is acceptable due to the nature of manual lathe work. I.e. You always take up the back lash in approaching the cut. That said, the iGaging linear scales from Busybee and others aren't particularly...
