AN8247SB Panasonic laser disk spindle Motor Controller datasheet.

Maybe an8247ssb can help me pls? What about chances to use arduino for controlling this motor? January 17, 7: April 23, 9: Douglas Berlier this motor spins too fast for You, to be able to get a visible, moving dot. If so, I would like to build one too.

I have the same unit, but my interest was on the other side of the box. By rotating the mirror very slowly by hand, I counted 6 pulses per revolution.

Comment moderation is enabled and may delay your comment. I have just dismantled my canon lbp January 8, 5: What I an8247bs was pin 5 is actually pin 1, and it is indeed power. I had a laser head I pulled out of a Sharp I think printer. Its very interesting i was thinking to use of this motors for demo show helicopter project.

Digging around in my junk box produced the power supply board for the laser printer. This must be the tach output.

April 22, 7: You could have found pinout easely a8247sb a chip datasheet, which is next to connector.

First I tried connecting a 10K pullup resistor to pin 2 on the motor driver board to 3.

July 25, I was trying to power it up, but no success. That was really great because I was worried that those two pins were I2C control lines which would have an8247b reverse engineering a lot more difficult. Because i have a lot of scanner motor from old laser printers. Tracing back through the power board I notice that it connects to a filter capacitor with a 25V rating.

On impulse, I dramatically increased wn8247sb frequency. Drop me a line in the comments if you think you can guess what my idea is, or to post your own ideas, or even if you find this information useful for your own project. What I suspect to be pin 5 appears to be the power supply since it connects to two very low valued resistors 0.

By changing the frequency, I could manipulate the motor speed. Xn8247sb my usual plan of attack does not succeed. By continuing to use this site, you are consenting to our use of cookies. The second step is an8247s examine the single 5-pin connector to see what I could figure out.

October 3, Most of the other pins disappear inside the undocumented chip. You must log in or register to reply here. I am looking at using this item for a BORG costume! I was busy with datasheets and other tips. I pulled pin 4 low, and the tiny mirror spun up with a whine to about 13, RPM as measured by the tach output!

It also had a 5 pin connection to the motor, but the pin-out was different: Articles Top Articles Search resources. I connected a function generator at a few kilohertz with a 3. Years after, your explanations were very useful to me after dismantling a very old laser printer and trying to zn8247sb up the scanner unit. April 27, 9: So pin 5 is a synchronization input.

One thing i would like to do is proceed the motor. I spun the mirror assembly, and I saw pulses! I was able to find the other side of the connector and quickly verify that pin 3 is indeed ground. Mosfet drain current spike and input current spike in full bridge inverter.
