I posted this question on another site, but haven't gotten a response yet, so I thought I'd get some people's opinions here. The motors I speak of on this post are all new LRP Vector X-11's that haven't been run yet. What I was wanting to do was take the sintered rotor out of the 4.5t X-11, and install it in my 5.5t and use the bonded rotor that came with the 5.5t, and put it in the 4.5t. (The 4.5 is the only X-11 motor that comes with a sintered rotor)...
Here goes:
I'm VERY confused..... I just got done switching rotors.....I took the sintered rotor out of the X-11 4.5t, and installed it into my X-11 5.5t for which I took the bonded rotor that was in the 5.5, and installed it into the 4.5..... Everything went together without a hitch....
* Realizing that (without any knowledge of how to tear down a brushless motor) all it took to remove the rotors from each motor were three screws on the bottom of the can where the pinion mounts....surprisingly easy, as there were NO shims or anything to fall out witch I was hoping wouldn't happen even though I wasn't sure!! *
Ok, now here's what confuses me.....both motors are now assembled fine, everything lined back up perfectly because I marked the endbell, can, everything so that I made SURE I put each motor back together exactly as they were, including the timing which I never changed either. SO, the 5.5t which now contains the sintered rotor, still feels like it did before when it had the standard bonded rotor in it!! :blink: I thought that sintered rotors/magnets were much stronger, hoping to spin the rotor in the can having it feel like it did when it was in the 4.5 can.....but it spun VERY freely as it did with the bonded rotor.... :huh: :\
Why is this??? And vice versa: Now the 4.5t CAN has the BONDED rotor, yet it feels like it did with the SINTERED rotor that originally came with it, by feeling like the magnets were much stronger, more like a brushed motor without the brushes installed and with strong magnets.... (in other words, I figured that the 4.5 can would now feel like the 5.5 did because of the bonded rotor it now has in it???) :blink: :S
In Summary:
So to make a long story short.....both motors feel exactly the same as if I never changed rotors, even though I did. 4.5 now has bonded....5.5 now has sintered....yet they feel exactly the same as they did before the switch when spun by hand inside the can!! I mean, it's VERY VERY easy to tell the difference as the 4.5 STILL stops MUCH faster, while the 5.5 STILL spins almost freely like there are no magnets (as it did before the switch)
My question, WHY???? Does it have something to do with the windings inside the can or did I assemble something wrong??? I made sure I assembled everything EXACTLY as it was because these things are precious and I paid a good amount of money for them and didn't want to ruin them before I even got to run them.
Anybody know what's up?? Will the 5.5 still have more torque though?
