Humanoid Robots Testing Equipment Tester 

Ring stators have concentrated windings and a set of coils around them.

The wiring and the circuit board attached to the second one probably handle the phase connections or encoder signals.

If you’re integrating them into a humanoid or other precise actuator, these ring motors would let you achieve a compact but powerful joint

Typically, you'd test these ring motors in a few stages.

First, you'd measure the electrical continuity of the windings and confirm that all phases are correct.

Then, you'd run a no-load rotation test—check smoothness, detect any vibration, and measure back EMF.

After that, you'd typically load it with a small torque and measure how much current it draws and how quickly it responds.

If you have encoders, you’d also check for precise position feedback.

Doing all this ensures the motor performs as expected before you integrate it
