Help identifying small electric motor.
(OP)
Hi all,
I've been trying for some time now to figure out how and what these motors are.
As it stands I believe they are some kind of 4 pole permanent magnet DC motor with an encoder but I could be horribly wrong.

There are some photos in this google drive folder.
I have a box full of these so it would be great to know what to do with them.
Thanks in advance.

Does any part of it attract a feeler gage when it's off?
I see six coils on six poles, fed by three wires.
Which suggests that it's a three-phase motor.
... with an encoder attached to the non drive end.
Which comprises, with a separate control circuit board, a brushless DC motor.
You need to find a box of circuit boards with matching connectors or cables.

The magnets are on the shaft. The grey cylinders.
Image 113543 is the shaft with the magnets and bearings etc.

OperaHouse - This could end us being my only option short of recycling them. What would I use to draw attention to them in that circle? Should I call it an SMI PMDC Servo or just a PMDC motor?
I've had a multi-meter across the wires that come off the winding and when I spin the motor I get spikes in the voltage when starting and stopping but nothing during rotation. I was spinning it with a drill so I wouldn't think speed was an issue.
