Hello, im working on a project involving a linear actuator+motor driver.
For now the prototype uses a L298N motor driver and a 3.2A actuator (I know the motordriver is limited to 2A... ).
I want to scale this prototype up using a 12V 20A actuator and a suitable motor driver, I have found this 35A(AEK-MOT-2DC40Y1) card using VNH7040AY motordriver from ST microelectronics.
To use the L298N motordriver it was fairly simple to find a library but I can't seem to find one for the VNH7040AY chip. Is there a way to run the motordriver on Arduino or can I only use ST's own platform to control the actuator?
(Im just a mechanical engineer with limited experience in electronics...)
I think it would be easier to roll your own MOSFET h bridge driver using a two complementary pairs. Coul probably be driven using the code you have now.
Okey. Thanks, but if I were to buy a motor driver, how would I proceed regarding library's/plug-ins? How do I find out where I can use that specific chip?
I wrote code for someone using this driver for a heavy-duty motion system and I was told it works very well. I don't personally have that unit, though. It just uses a standard speed & direction input.
Pololu has the best selection of motor drivers, but you need to know the start/stall current of the actuator. If 20A is the rated current, the start/stall current could be 100A or higher.
Yes it looks like it. It leaning towards the JRK G2 cards. But it seems like they are controlled by serial/i2c protocols, does that mean that I can control it directly from arduino or?
