# Looking for identification of an item

I have had some trouble identifying this piece of hardware, even with the help of the inter webs. I have disassembled the printer (Brother HL-2270W or a similar device), so getting it to run is a bit of an issue for me too, so. My questions is: what is this device? It obviously looks like it is a motor or servo or etc of some sort, but specific name would help. Then my next question would be this: can I somehow reuse it with, say, an Arduino Uno r3?

Note: I am new to this sort of thing, and so would not be surprised if something i ask is misrepresented in some way or vague. Thanks in advance for understanding.

• Where in the printer was it taken from? This will help identify the part easier. – Dean May 29 '13 at 2:09
• It was taken from a side, connected to a rather large gear(compared to the rest), and that was connected to several other gears.. Specifically what part of the printer, I am unsure.. I'll see if i can find out. – user24527 May 29 '13 at 2:10

It looks like a 3-Phase Brushless DC Motor. The U,V,W markings are apparently standard notation. The three little chips labeled HU,HV,HW are likely Hall Effect Sensors (or simply Hall Sensors) for position/speed feedback.
