I have a couple of 8" drives Mitsubishi M2863 slim type that I recovered I
think around on 1990 both in excellent conditions with which I created
images and written several floppy disks 8". For some reason, including my
incompetence, both their spindle motor do not run any more. And powering
correctly with only +24Vdc the circuit part of the engine rotation control
of the disk (called spindle motor) begins to smoke near a chip LB1620. The
schematic contained in the maintenance manual of the drive includes
components of other different model of spindle motor circuit. If that were
possible, how could I to be able to run the drives correctly: reusing partly
engine or even replacing it with analogous maybe even creating handcrafted a
motor with pieces of recovery and manage the number of RPM (I think 360rpm
for 8" drive) possibly with special circuit ?
At this moment there is a shortcircuit between +24vdc pin and ground pin.
Spindle motor SRC SHINANO TOKKI CORP. MADE IN JAPAN 702V
Modello DLF-3ME DC24V
Any suggestion is welcome.
