Hello everyone,
I've been searching over the internet for a while and i didn't find anything useful.
I have a dc motor and I don't know what type it is, nor what is it for.
I don't know where I got it from.
Can someone help me identifying it ? (sorry if I'm not at the right place)
Thanks in advance.
Christophe.
PS : I'm french so please forgive my english :)

Appears to be a direct drive P.M. type, so first just feed it with a small DC power source and see what RPM results, typically the maximum would be around 2500rpm so you could extrapolate the required DC from the resultant test, (voltage/RPM).

Appears to be a little more than the typical DC motor, also look like what appears to be a governor of some sort?
Originally though it had two leads but there appears to more than two?
Is that slip rings on the rotary part (armature)?

You were right, I measured RPM at 5volts with the microphone method and I get about 2150rpm.

Sorry but I don't have enough knowledge to answer your questions.
If by leads you mean wires, yes there are three.
I don't what governor and slip rings are :/

On a french forum someone told me it could be a turntable motor.

Max is right its either a turntable motor or audio cassete motor & the mechanical governor is usualy set at 2400RPM. I have a couple of those motors & some where how to set up the speed. If you want to check the speed I use a contactless tacho that picks up infrared reflection from a mark you put on the pulley. The motors I have came out of a record player that ran on 9V DC. These things come in 6 or 9 or 12V DC
