I've been thinking on how to build a tool changer for NMTB, without
having to add a spindle encoder and fine motor control. Since the
spindle has two drive lugs, probably an alignment jig that pinches

Is the drive train self locking, so that if you loose power, the load
does not drop?
Or do you have a brake on the motor or someplace else?
One thing I have heard that can be a problem when using a squirrel cage
AC motor like this at very low speeds, is that the motor can overheat

Field oriented control can be considered just another name for vector
control in this context. There is a distinction in that a vector
*controller* is the name given to the functions which convert the 3-phase
motor into a 2-phase reference frame upon the rotor. FOC is the whole thing
- i.e. using

You might find that if you add some bias to the PID controller then
you can make the behaviour more symmetrical. Hopefully symetrically
good, not symetrically bad. (you should find you need less P to get it
to move up)

The joint is moved by means of a lead screw of 50 mm of diameter and 8 mm
of pitch. The
That is a good price for a drive that can do that.
Sounds like the motor will last a very long time if you run it as you
describe.
