Likely was a relay controller and MG set in the original installation. The traction machine is in amazing condition, communicator is very clean, no arcing from the brushes. I am curious if this maybe a mini traction machine, with the lower DC voltage.
Seems very odd seeing the commutator at that end of the motor! I must have seen thousands of commutators in 42 years as an Otis engineer, but the comms were always at the other end.

OMG they left a mousetrap on top of the machine??? HAHA why do mice want to be here? 😆
Lol no idea. Maybe they like to look down the shaft 🤣

For a few months I loved staring at pictures of universal/brushed dc motors because I thought they looked nice. Now I don't.
Lol, did anyone notice the mousetrap?
MCE controller... I have thousands of hours with those...
What's this other smaller silver box on the ground for?
That's the centrifugal governor. It is calibrated to active the car safeties if the elevator overspeeds.
@@williamford7966 cool, thanks for explaining 😎👍
