There has been some discussion recently about the need for a 5v supply to the pulse circuit used on Fibo motors. I myself have several Fibo's and have solved the problem in the past in various ways. Since most of the positioners/receivers about at the moment only cater for reed switches, I decided to have a look at modding the Fibo motor to a reed switch.
After a bit of investigation, experimentation and choosing the right bits and pieces, it was an easy mod to do. I have modded my motors in use and also my spares.
The attached pics show the mods.
The first pic shows the the bits required.
Drilled gear wheel, drilled to take either one or two magnets, and a couple of lightening/balancing holes whilst I had it on the machine. Some positioners may not accept the double count freq. and/or the total count. Some only count up to 999
Top steady plate grooved to locate the reed a little. Two miniature disk magnets. Reed switch, with suitable wire
The second pic. shows some pre-assembly, showing gear with one or two magnets. and the reed switch with wire attached.
The third pic. shows the assembled motor with a double pulse wheel.
The mods do not drastically change anything, the optical pulse system could be reinstated quite easily, it would only require a bit of black tape over the unrequired holes in the gear wheel, and the optical sub ass. remounted. I don't know of any reason to change back, but the possibility is there.
If anybody wants to mod their own motor, I will help in way I can, just ask
