Hi everybody,
I bought 3 Sanyo Denki (103H7126-1740) stepper motors to build a CNC but I got some problems with drivers, I tried the L297+L298 stepper driver but the L298 gets hot after a while and burn out, then I tried the L297+ 2XL6230 which turn off once hot, I also tried PIC microcontroller + Mosfets (TIP161&TIP145) but the mosfets burn out after few minutes. I'm trying to make them work fine months ago with no result.
The motors scpecifications are:
- Bipolar
- Current: 4 A
- Grade: 1.8 ° + / - 0.09 °
- Holding torque: 165 Ncm
- Resistance: 0.48 Ohms
- Inductance: 2.2 mH
- inertia: 360 Kgm ² x 10 -7
- Theoretical acceleration: 45,800 rad x sec -2
- Constant voltage: 31 V / krpm
- Weight: 1 Kg

Help me pleaaaaaaaaaaaase :'(, thank you verry much.

The DIY open source THB6064 is a perfect candidate for a 4Amp and 2.2mH motor.

Thank you so much Lucas for your reply but I didn't find the THB6064AH chip in the store.

Almost everybody uses full partkits, some only a PCB and chip.
I can supply the chip only, please send a PM if you need some.

The link does not show a motor.

@H500:
That link is automatically created by CNCzone to one of their sponsers for additional income, it's not a link to his steppers, the spec's are in the first post. I have been confused by this for a while also, you can turn most of these auto-created-links off in the user control panel.

@scalance:
Your first post showed that you are a DIY guy, that's why I linked to a DIY solution wich is a good drive for these motors.
There are other drives: Gecko G540, Leadshine... but these aren't cheap.

Thanks Lucas, but as you said those drivers aren't cheap and I like to make myself things so I undertand how they work exactly

On that page there's : 416073 Replacement THB6064AH chip.
Click on that and there it is: 6064 Stepper Motor Driver (CHIP ONLY!)

A few posts back you said the same, I then replied:
"I can supply the chip only, please send a PM if you need some. "

What more do you need?
