Hi,
I don't have much experience in DC motors other than basic speed control using PWM but I would like to build a very simple small coil-winding machine consisting using this simple lathe from Amazon:
https://www.amazon.co.uk/gp/product/B07HKZPDDD/ref=ox_sc_act_title_1?smid=AJPBV39SXHGIV&psc=1and I am going to guide the wire by hand.
It uses a 12V DC motor and ideally I would like it to:
- run at very low RPM, maybe even as low as 30 to 60 RPM
- maintain constant speed regardless of load (a very small range in load). The load is just my finger which presses against the coil while it is being wound
From past experience, especially at extremely low RPM, the smallest change in load made the DC motor behave a little erraticaly.
Are there simple low cost solutions/controllers that can achieve both of the two points mentioned above?
Perhaps some back EMF controller or some other technology/system/solution?
I could not find any on Amazon (but perhaps I was searching for the wrong keywords)?
Thank you
