Need Help!- Building driver for bipolar step motor

[boogi1976]

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?

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

Nobody?
I saw TMC249.
Any suggestions?

Have you looked at the Toshiba TB6560 driver Chip?

This one can do 5amps. http://www.cnczone.com/forums/steppe...o-stepper.html



I just realized that this is an old thread.

Hello;

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

Is the current of 3,5A enough for my motors?

[boogi1976]

Thank you Kreutz,

I was looking your post about Allegro A3986 and schematic called ster3986-07_sch.png.
I am planing to buid it and I was wondering could you send me values of components on schematic?
Thanks in advance

You list your motor in your first post as 3.6A.
Yes, 3.5A is enough for your motors.
