First of all I would like to hello everyone on forum and say this is my first thread.
I am in stage of collecting pieces for my machine.
I have 5 of Nanotec-Munich Modell: 4T5618S2404-A motors.
Bipolar-Parallel
Nennspannung / Phase = 1,25 V
Nennstrom / Phase = 3,6 A
Nennhaltemoment 2 Phasen = 0,79 Nm
Schrittwinkel = 1,8°
Widerstand / Wicklung = 0,35 Ohm
Induktivität bei 1 kHz = 1,2 mH
Wicklungszahl = 4
Litzen = 4
For a long time I am looking for drivers for them.I have to say that I want to build them (DIY).In first I was thinking something like L297/L298 or similar.
But I read it would be better that drivers have microstep mode.So,I started to search for that kind of drivers.I found a few of them but none for current my motors are rated( 3.6A ).
In one moment A3986 seem to be prefect for me ( one small chip ,few external components ,current limit, external MOSFETs...). But as I have read A3986 has some problems.
So,I am asking can somebody help me to solve my problem - DIY driver for motors above?
