Motor stator resistance
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. |
Every motor I would have checked to see if can timing is off from actual. If yours is it 50 pulling 9 amps I bet actual is closer to 53-54. 7.06-7.2 fdr is good for clay on most tracks. 17.# numbers is resistance on the windings. From solder tab to ring on the other side. You have a 17.5 motor. The 10.6 resistance is 13.5 motors. |

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. |
