Treadmill Motor

[nhengineer]

Lots of great ideas about re-purpose of treadmill motors on this forum. I've found they can be from 90 to 130VDC and more that 2½HP. The last treadmill I took the motor from had a transformer choke wired to it and maybe the others did too but I missed them.

Question:

If I re-purpose the motor do I also need the choke even if I used the homemade SCR drive described in other threads?

Point of Interest:

The treadmills with incline have a boss 120V gear-motor with pinion, small rack and one I found even had a photoelectric position sensor on it. I'm sure to find a use for that. Does anyone know how to find out what the pinion pressure angle so I can get a longer rack?

You all would be amazed at the treadmills that are scrapped. One was still in the original box, not even assembled yet. I love rich people.
