Anthony Lindsey Posted August 4, 2023 Posted August 4, 2023 Is this a DC fan? I see what looks like Brush holes on each side of the bearing on the front. Quote
Steve Stephens Posted August 4, 2023 Posted August 4, 2023 (edited) Could be AC as 25 and 40 cycle fans from some makers were AC with brushes. Is there a motor tag that will tell if AC or DC? Edited August 4, 2023 by Steve Stephens add info Quote
Anthony Lindsey Posted August 4, 2023 Author Posted August 4, 2023 I only have access to pictures. Are those brushes on the front? Quote
Russ Huber Posted August 4, 2023 Posted August 4, 2023 (edited) Anthony, ask yourself how big the commutator would be to fit inside along with the front bearing. If those were brush channels, the brushes would be missing or just skimming the bottom of the commutator. How about a funky front rotor shaft lubrication design?

Anthony Lindsey Posted August 4, 2023 Author Posted August 4, 2023 Great observation. I hadn't seen that one before. Quote
