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! Prev Next Motor driver ICs. Feb 10, The phase relationship between the signals opposite that for forward operation, and the re- 3 verse rotation detection circuit operates.

Excuse me if it was a stupid question but which pins is the motor connected to? Resistance values are typical values. BAFM datasheet and specification datasheet. Electric Motor Design and Ba6489fm. Last edited by George; Feb 10, at What do I need to run this CD Rom motor? The extra 2 pins are not required. These ICs possess a short brake and reverse.

If this is too hard then you can use the whole board as is, but you will have to isolate pins 18, 22, and Return to Power Systems. Ba684f9m Me Forgot Password?

3-phase Motor Driver For CD-ROMs

Cd rom motor needs shaft???? As far as I can tell, the only thing different about the BA apart from different pinouts ba66849fm that it has a separate pin for direction control.

The Hall elements can be connected either in series or in parallel. The output goes OFF, and becomes open circuit. Download datasheet Kb Share this page. However that may be OK for your application perhaps you just want to see the motor running?

Feb 08, Posting Quick Reply – Please Wait. I want to get my CD rom motor spinning. Elcodis is a trademark of Elcodis Company Ltd. 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 datzsheet again.

Short braking operates re- gardless of the torque command signal. Oct 09, Oct 11, Feb 07, PS pin 23 and SB pin 18 must be connected to Ground 0 volts or open circuit.

All other trademarks are the property of their respective owners. These ICs possess a short brake and reverse- bq6849fm brake for two types of brake functions, and also contain FG datashwet and rotation direction detection FR circuits, making them high-functionality and high-performance ICs Hall input The input circuit shown in Fig.

It may be possible to cut the motor controller section off the main board, or you datasheft just remove the chip and make your own PCB for it. Jan 17, Using the existing cable and PCB will ensure that it is correct.

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. 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?

The motor windings are connected to pins 2, 4 and 7 of the BAFM. Feb 09, Sign up now to remove ads between posts. 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! Apr 17, The motor position data input via the Hall pins is amplified by the Hall amplifier, and formed into waveforms by the matrix block.
