Just tried out another HDD board. This one had the 4 pads as you describe. The motorconversion runs pretty fine on it, but with very little torque; it's easy to stop it from turning by holding the shaft.

Also, this other board seems to turn off power to the motor after -exactly- 60 seconds.

The driver IC is a Hitachi HA13481. Have got the datasheet for it now.

Good fun, but not of much use. Still, might be fun for someone to connect their axial flux generator to an old HDD board and see it run as a motor.

Peter.
