Testing with a floppy disk drive motor

2005-07-10 FDDtest: weight-lifting test for fdd head assembly stepper

160 grams with 200 mA power from ICD2 (including 100 mA or less that picdem2plus board uses)
[MVI_0006.MP4]

Detail of 160 grams 200 mA power head movement, 66+66 ms step interval

Detail of the 160 grams weight - a pack of 10 discs

Giving FDD full power makes it stronger at faster speeds! This is 16+16 ms step interval. 16+16 ms
is fastest speed I could make it step. At 12+12 ms step interval it stands still and makes 40 Hz tone.
At 16+16 ms it could carry 130 grams. It could not carry this weight with 200 mA power at this speed though.
