Hello,
I got a Panasonic Minas S series motor from a friend, and have just gotten it running with my brushless drive and controller. This motor has the commutation signals (sometimes called Hall signals) turned into a serial bit stream on one differential pair, so I had to come up with a decoder for it. Once I had that figured out, I tried it with my brushless servo amp and it works VERY well, and is smoother than any other brushless motor I have tried so far. This particular motor is the Panasonic MUMS042A1A, but I suspect this decoder will work with all the motors from that series.
I am trying to gauge the interest in bringing this out as a product. I think a bunch of these motors were sold on the surplus market about 2007 - I should have bought some then!
