Re: [Emc-users] Success driving Panasonic Minas S (MUMS) brushless motors
Jon and Dave, That seems to be a nice small motor/ drive combo. I have 4 of them. I have one of the drive/motors running on a Motenc lite board. Other work pulled me away from it. I need to get back to it and tune the drive.

[Emc-users] Success driving Panasonic Minas S (MUMS) brushless motors
Please excuse a short commercial plug Dave Engvall gave me a Panasonic brushless motor at the CNC Workshop to see if I could figure out how to run it. It took me a LONG time to get around to figure it out, but I have finally got it! It has a serial output that contains the commutation signals, so I have to add a little decoder for that signal. Otherwise, i have gotten it to work with my Universal PWM Controller and brushless PWM Servo amp. It works quite smoothly, better than a number of other brushless motors I've tried. The motor I have is a Panasonic MUMS042A1A, but I would assume all the motors in that Minas S series would work as well.
