New scanning motors? - Laser Pointer Forums

kiyoukan · 11-06-2009, 04:59 AM

i found this when looking for scanner motors.
COPAL POLYGON MIRROR LASER SCANNER - Surplus Shed
I see its used for scanning in medical equipment my question is what type of motor is that? stepper, servo.
Can these be used to make a laser scanner?
Depending on the type of motor how do you drive them?

(i searched the forums and got someone with a post but no details were given on how they worked. Google turned up empty.)

They must be Stepper motors right?
16 leads...

ElektroFreak · 11-06-2009, 05:18 AM

Those are just a multi-sided mirror that spins on a pretty much standard motor.. A laser beam projected onto it forms a straight line. That's all they'll do. They come from laser printers and copies.

kiyoukan · 11-06-2009, 05:22 AM

hmm i found them on another site that said they were steppers.
http://copal-electronics.info/en/000aa/00ec3.pdf
this is the only documentation i could find i dont know if there bi polar or uni.
does jitter mean vibrate or is it only just a line?

ElektroFreak · 11-06-2009, 05:28 AM

just a line.. http://www.mi-lasers.com/stock/OPT-PS-2c_300.jpg

kiyoukan · 11-06-2009, 05:33 AM

hm. I would think with that many leads it could be used to do more than just spin but thanks.

ElektroFreak · 11-06-2009, 05:36 AM

The extra leads are for precisely controlling the motor's speed and monitoring it's behavior.

Things · 11-06-2009, 10:38 AM

Yeah, they are steppers of a sort, but useless for scanning anything but a line. If you wanted to get tricky, you could set 2 up in an X and Y config and try raster scanning, but that is some very advanced stuff.

carmangary · 11-06-2009, 10:46 AM

If you read it carefully it has something like 6 or 8 mirrors mounted on the shaft and it just spins around really fast. It would make a nice liquid sky effect and you might be able to use it in some kind of raster system if the speed control is precise. For the most part, they aren't worth messing with, though.

JDOLECKI · 03-14-2010, 02:21 PM

Its a 3 pole brushless dc motor.

3 of the wires are for the motor.
The rest are for feedback / motor control.

I have a drawing of the wires if any body is interested.

kiyoukan · 03-15-2010, 12:41 AM

Hm well thanks for the info.
also Welcome to LPF i see this is your first post.
Do you know by owning one or just found documentation?

JDOLECKI · 03-15-2010, 01:48 AM

Were using it in Physics Research.

I own 2 now

I took the first one apart

Heres some PIctures of the inside circuit board

Im building a driver for the motor now. Thats how I came across this web site.

The first pic shows the little black Square thats a hall effect sensor and there is 1 magnet on the bottom of the rotor. im assuming the orginal purpose was for RPM.

The second Picture shows the 3 Hall effect sensors for Phase feedback.

Im Using a LSI/CSI Chip to control it. LS7260 Is the chip number.

kiyoukan · 03-15-2010, 02:21 AM

wish i knew more... i understand so little still about electronics. i just got the 555 ic down and just got started on pics

Things · 03-22-2010, 10:14 AM

Driving stepper motors is easy if you used something like a PIC or uC and a transistor array. All you do is switch each coil on and off in sequential order.

kiyoukan · 03-22-2010, 11:13 AM

I know how to drive them i made a controller for my cnc machine. but that was not all on my own power their, but no matter as long as i can learn it and keep my notes i can do it again.

yotanglaser · 04-13-2010, 08:04 AM

wish i knew more about this ,i understand so little still about electronics.

kiyoukan · 04-13-2010, 08:47 AM

Hey dont worry i still know next to nothing i have been trying to build a circuit for weeks now and still cant get it to work right but i am very very close.

Tech_Junkie · 04-13-2010, 08:59 AM

He is from yotang and trying to get his post counts up making useless statements. Its kind of a funny comment for a person selling lasers.

kiyoukan · 04-13-2010, 09:07 AM

lol yeah but i have all my thread tied to my email so i always notice them, i never know how to stop them but id don't matter much.
It seems me and you don't sleep much. i look at your posting times and they only have small gaps between posting.(2-4h)

Tech_Junkie · 04-13-2010, 09:22 AM

I only sleep 2 - 6 hours at a time because of pain.

kiyoukan · 04-13-2010, 09:58 AM

So i noticed.
I have a sleep disorder close to borderline insomnia.
There is a feeling when you hit the 3rd day of no sleep that makes life very very difficult according to people close to me i couldn't speak English correctly and to the point where they knocked me out with vicodin.
But make great for finals i can cram study more than any one i know.
