What Kind Motor is that?

What Kind Motor is that?

(OP)
Im wondering what kind of electic motor that is? anny clue.



RE: What Kind Motor is that?

Looka more like an encoder.

Where is it? In a robot limb?

Hard to tell with such limited info. Assuming this is an articulated actuator arm of something sand that motor is controlling the articulation, most likely it's a servo motor, and appears to be using what is likely a planetary gearbox. So it likely gets its torque from a small motor like that in exchange for very slow speed by having a high gear ratio.

okay thank you

it is in a robot eel. Its called Eelume: https://eelume.com/

OK, then there isn't any need for high torques or high speeds. Thrusters are not in the joints, only attitude adjustment and holding torque, which may even be the friction in the gears. So I guess that Jeff is right. Little steppers with high reduction self-holding transmissions. Looks smart. Treasure-hunt?

Yeah, given the application, I think Gunnar's idea of it being a stepper instead of servo is more likely, especially when I noticed the ribbon cable. Still looks to be a little planetary gearbox on the end of it though.

When digging to try to see if anyone mentioned what kind of motor it is (all I could find was "biomechatronic"), I did stumble across this:
"Eelume robot can be provided with an artificial intelligence software so that it can navigate and move even without remote control. This is an important step towards more autonomous underwater vehicles that do more than just inspection."

OK, that's a little scary... If they get the size down a little more, these things could eventually start crawling out of your toilet!
