Motor control IC


Recommended Posts

I have a motor control board that drives

a 3 phase switched reluctance motor.

I am trying to identify the control IC that

is being used. So far the only thing I can make

out is the date code. It is a 28 pin Dip chip.

Has anyone seen this one before or have

any ideas. I will attach a picture file

Hi Glen


This looks to me like it is a custom device, could be an embedded processor or masked ROM. I suspect the first. I can only suggest that you should contact the manufacturer and ask them.


Best regards,
