3-phase Motor Driver For CD-ROMs

I want to get my CD rom motor spinning. Feb 06, However that may be OK for your application perhaps you just want to see the motor running?

PS pin 23 and SB pin 18 must be connected to Ground 0 volts or open circuit. It may be possible to cut the motor controller section off the main board, or you could just remove the chip and make your own PCB for it.

If this is too hard then you can use the whole board as is, but you will have to isolate pins 18, 22, and You will need to control this yourself or bypass it and feed voltage directly into pins 26 and 27 to get power to the motor.


Just hook the 3 motor windings up to the ESC, and ignore the hall sensor outputs! Thanks very much I was spinning my self to get this information but I think I’ll go for the hard way because I don’t know where I can get an ESC in Egypt thanks again and please don’t get bored if I ask you anything else because I’m still a rookie.

Excuse me if it was a stupid question but which pins is the motor connected to? The motor windings are connected to pins 2, 4 and 7 of the BAFM. The motor will not run unless all the wires are hooked up correctly there are about 25 possible combinations, but only a few that work!

Using the existing cable and PCB will ensure that it is correct. Feb 07, The extra 2 pins are not required. Feb 08, It didn’t work I don’t know what I have done wrong the motor isn’t spinning and the IC gets very hot may be I connected 2 wires together that shouldn’t or destroyed the IC while I was removing it anyway thanks again.

Feb 09, Last edited by George; Feb 09, at As far as I can tell, the only thing different about the BA apart from different dataaheet is that it has a separate pin for direction control.


So it should work fine, just make sure to match each pin to ba6849rm function! Feb 10, I compared the data sheets of the two ICs there is no big difference just the names of the pins and a thing in the middle of the diagram and pin 26 so I will connect the same way as the last IC right?
