How do Stepper Motor Drivers Overcome the Speed Restrictions Due to a Charging Coil?

I am sure you will not offend anyone. Sadly I am an incorrigible know it all and my foot is permanently in it

Hi Matthew

Just to clarify Robin’s earlier comment. You are not offending anyone here. Far from it, you are asking interesting questions. Robin was referring to new posts from builders who come on this site having bought some big motors and are sometimes offended when told they have bought the wrong thing. It has happened a lot.

Thank you, I understand, I think I must have misunderstood originally - I definitely didn't want to be putting anyones nose out of joint, especially after having had such good advice on here in the past.

Aliexpress.
I've not personally used them (I opted for Kinco from Zapp), however at least a couple people on here have used the cheap Chinese servos without any problems.

Drive/Motor set can be had for under $300.
The main drawback is the drives are only powered via the 240VAC, so if they lose power, you lose position. Whereas the logic in the Kinco drives is powered via 24VDC, so you can cut the 240VAC (i.e. an estop) and all the encoder circuitry remains active.

Thank you, it's definitely worth thinking about - I started learning a little more about servo motors after I saw your reply. All this time I was under the impression they all had a built in gearbox like those servos you get in model-aircraft and RC-cars, but that doesn't seem to be the case!
