DC,

It's interesting that those HYST motors have flats on the armature.
The HYST motors I've seen have no flats and can lock in any
random position at start-up.  It would appear from all this that
there are different types of HYST motors.  Folks still need to
be careful with other types of HYST motors; ones other than
the ones you sold to folks.
