With the Brushless Motors, we've seen using inductance as some type of measuring standard that has never before been done in R/C Racing.
What kind of variance numbers would we have seen with the old Brushed STOCK Armatures or 19t Arms?
What EXACTLY do these numbers mean...and HOW do we equate it to ON TRACK Performance / Horse Power?
Why are ALL mfg's not held to the SAME # range? After all, if a piece of wire is a KNOWN distance in length, wrapped the same number of times around it's core...should not ALL BRANDS of motors numbers be within a certain +/- tolerence? (If the design and materials were BLUE PRINTED they should)
Since NOVAK set the stage for Brushless Motor Racing we have seen a lot of changes already.
New Manufactures in the R/C Motor Game
New types of testing procedures (and tolerance numbers)
New types of dyno equipment
New ESC features - with added PERFORMANCE enhancementI personally hear a lot of talk about numbers on the B/L motors, and someone having a perceived advantage with them. But there are a TON of racers that have no idea what those numbers mean, or how to use them to their advantage.
This also goes for Rotor strength numbers.
A SMART racer never shows his true hand..escpecially if he's worked hard for an advantage...and numbers get HYPED and Sensationalized, and on the flip side of that...they get played down, if they have a number that was WAY out of line.
Recently, NOVAK quit offering Inductance Numbers in part because their appears to be a much larger variance going on, at least with their motors...for what ever reason. (Tightness of the wind...I don't know) , but before they did the had a pole to pole number of 140 listed, then a pole to ring number of 53.
Now, they are testing and labeling their motors with milli-ohm numbers on a tag under the purple ring.
Has anyone in the FIELD started looking at these numbers to see what kind of variance/tolerance there is?
The magical numbers used in ROAR as listed on their web site (inductance) is as follows
21.5
Novak 52.7
Tekin 49.5
Trinity 55.0
17.5
Ass/Reedy/LRP 38.5
Hacker 33.0
Losi 32.5
Novak 36.5
Orion 31.5
Speed Passion 34.5
Tekin 33.0
Trinity 34.0
So in the real world - how much can PERFORMANCE be expected by "The Numbers"
And how should the WORLD Standards be set?
this info and questions were only asked, because I've been asked over the past couple weeks about some of this info by a handful of racers (Not my series racers) and since we are only affected by NOVAK numbers directly, I really have no clue where the other motors fall in by the numbers.
