| 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? Boogi P.S. Since English is not my mother tongue I have to apologize if I made some mistakes |

| This one can do 5amps. http://www.cnczone.com/forums/steppe...o-stepper.html I just realized that this is an old thread. Last edited by KOC62; 02-17-2012 at 08:15 AM. Reason: Old thread |

The above mentioned drive is neither for sale nor available for DIY anymore, the bipolar output stage's design and commercialization rights were sold a few years ago to a local company who uses them in a proprietary robotic mechanism. The PC interface (K4) board's schematics, firmware, B.O.M. etc are posted on a CNCzone thread and are 100% free, you can use the K4 PC interface with 80v 8 Amps unipolar (Mardus Kreutz) power stages. Note that the K4 requires a few 0603 SMD components and the assembly level is not recommended for beginners. Best regards, Kreutz |
