connecting to an Oriental Motor TMP-1 Torque Motor Controller
the tension on film in film scanner controlled 2 oriental motor 4tk10a-aul torque motors. understanding of how works torque motor, when given 60v ac, act tensioning device on film. it's not winding film, it's maintaining tension - if slack occurs, picks up, when slack gone holds there. there's 1 of these motors each side of scanner (one feed, 1 take-up reels). in original design, there no external motor controller, per se. handled feeding 60vac gigantic transformer (which i've removed), through potentiometer set torque (i think), , relays turn on , off. since removed transformer, i've replaced device sold oriental motor that's supposed take place of custom wiring manufacturer of scanner used. tmp-1. this device seems fit, because can controlled arduino. nice able control direction software, film can wound in opposite direction, want able load both winds. in case, ain't working. believe i've got connected correctly make work in clockwise ...
