Elcodis is a trademark of Elcodis Company Ltd. 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. Jan 14, 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.
How go i get more thrust in my Cd-rom motor!! The motor position data input via the Hall pins is amplified by the Hall amplifier, and formed into waveforms by the matrix block.
Feb 06, What do I need to run this CD Rom motor? 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?

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. Electric Motor Design and Construction. So it should work fine, just make sure to match each pin to its function! Feb 09, Copy your embed code and put on your site: Just hook the 3 motor windings up to the ESC, and ignore the hall sensor outputs! These ICs possess a short brake and reverse.
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! Short braking operates re- gardless of the torque command daatasheet.

I want to get my CD rom motor spinning. The motor windings are connected to pins 2, 4 and 7 of the BAFM. Excuse me if it was a stupid question but which pins is the motor connected to?
Oct 11, Cd rom motor needs shaft???? These ICs possess a short brake and reverse- rotation brake for two types of brake functions, and also contain FG output and rotation direction detection FR circuits, making them high-functionality and high-performance ICs As far as I can tell, the only thing different about the BA apart from different pinouts is that it has a separate pin for direction control. PS pin 23 and SB pin 18 must be connected to Ground 0 volts or open circuit.
These signals are input to the output driver that supplies the drive current to the motor coils. Prev Next Motor driver ICs.

The phase relationship between the signals opposite that for forward operation, and the re- 3 datzsheet rotation detection circuit operates. If this is too hard then you can use the whole board as is, but you will have to isolate pins 18, 22, and Oct 09, The phase relationship between the Hall input signals and the output current and voltage is shown in Fig.
Using the existing cable and PCB will ensure that it is correct. Bruce Abbott We want The extra 2 pins are not required.
Hall input The input circuit shown in Fig. Last edited by George; Feb 10, at Sign up now to remove ads between posts. 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. Resistance values are typical values.
