Posted on May 17, 2011 at 10:17 Hi,
I am interested in driving the low voltage (12V) BLDC motor in a small industrial pump application at low-ish RPM (2000-8000). I am a new comer to the ST range of chips and I would like to know:
What is the difference between the ST7MC family chips and the presumably older ST72C141 chip Kanda supply in their motor control kit, and are they interchangeable.
Is the intention for the MC range of chips to be a self contained part, like a replacement for an analogue chip like the ML4425 for example, which just happens to have some spare cycles for doing other things as well. It seems to be going that way, with the automated code generation that seems to be available…
Does any one know how the ST7MC chips compare for ease of use / price / performance, with the dsPICs that can apparently do motor control.
How do the Kanda and Softec motor control evaluation kits compare.
Does anyone know of any similar products from other manufacturers that I should be considering?
I have been looking into this for a few days now, and am still unsure which is the best way to proceed, any help would be appreciated.
Cheers
dc
