Hello,
I am looking for information on the HA13626 (Hitachi?)
it is a three phase brushless dc driver on a hard drive circuit board. I am trying to figure out how to make the disk turn at full speed constantly.
as it is it turns on twice for a few seconds then shuts off.
the hard drive is dead as far as data goes. I just want to use the motor and disk for a gyroscope.

on another hard drive board I have a chip with the fallowing numbers, top first; L6278 1.2E

B996W0411

I think this is the driver, probably three phase bldc.
I want to do the same to it.

any info that would help me figure this out would be appreciated.
data sheets are usually enough.
