So I thought it was time for me to try a newer motor, got myself a Trinity Xfactor 17.5. As I opened the box, the sticker with stator resistance reads: 17.7 / 17.6 / 17.7. I asked around and people at the track didn't really tell me what that meant, all they said is that theirs came at 10.6 or so.

What exactly do those numbers mean? Did I get a "bad" motor?
Do I have to gear it differently because of those numbers?
My timing came set at 50, drawing 9.1A - I thought it was pretty high, with FDR at 7.06, the temps are above 140F after a 3 minute run

Edited the post to be more specific about stator resistance.. I thought the sticker on the motor box showed currents at first

Your motor is not a bad one, 10.6 would be a 13.5t motor. I would go to a smaller pinion to help with the heat. The newer trinity motors like a higher fdr.

Here is a guide to the motolyser and what "most" of those measurements mean - https://www.motolyser.com/wp/wp-cont...IUserGuide.pdf

However, it doesn't reference resistance though. Basically, the lower the resistance = the faster the motor. Like the guy mentioned above, a 13.5 reads 10.6 (for example) and a 17.5 (yours) reads 17.7.

.

The values mentioned on the box are for each stator phase.

The lower are those values, stronger will be the stator. Inductance have a major role to play in.
