sintered rotors

EB Rules State:

Manufacturers and Importers should note, that if a range/type of motor is to be retailed with a choice of armature design, then a sample of each armature design (up to a maximum of three) must be submitted. The design samples are required to accompany the motor when it is submitted for homologation. All variants homologated must be available for retail purchase.

Your argument is that a brushless motor has a rotor not an armature. Well a quick search of wikipedia shows that:

In electrical engineering, an armature is one of the two principal electrical components of an electro-mechanical machine--a motor or generator. The other is the field winding or field magnets.

So using a brushless motor as an example would mean the armature is the magnet, also known as the rotor, and the field winding is the wire/can which is the second principle component.

let me guess you race tourning cars too?

the motors are legal (that have been homlogated) and as from april so are the rotors, it makes sence to allow the two two be used togeter by all

i blew a nosram std rotor to bit, and its being replaced by a sintered (which wont be used till april) you do know the sintered are less liable to fail and to over heating? makeing them even better value!

First Point: I totally agree. Mine has run faultlessly and I love the not skimming every run.

Second Point: I'm sure they will be allowed to be used together, when a motor is homl that is homl with a sintered rotor.

Third Point: Are sintered less liable to fail or is that hear say? I have heard stories of sintered rotors failing as well as bonded. I have never seen either only what I have read, so don't take this to mean much.

Sintered are also apparently a must for touring cars, but the first major race to allow sintered rotors was run with a brushless using a bonded rotor.

Dam wrong again not doing to well am i


i have ben runing touring at BIWS where lipo, brushless and sintered are allowed, seen std rotors go but no sintered and i have not seen or heard of sintered failing, to be honest i have also been told sintered are more important in the lower winds ie 5.5 and 4.5 cuz of the rpm,(which prob rings true to tc) but that all do benifit from running em.
the way sintered is made makes then more durable
some site are claiming if you run sintered the blue temp wire on novak an be removed to prevent thermalling
defo my mamba has them and they do go well

Mark, you seem to be missing my point I said that if all motors are available with both sintered and bonded rotors, then there is no problem - weather they have to be resubmitted - or if the EB change the list to suit does not matter a s@!*.

What does matter though, is if they do not make their range available for sale with sintered rotors throughout. If the only LRP/Nosram that is available with a sintered rotor continues to be a 4.5, then i'm not convinced that you should be allowed to take a sintered rotor and run it in a 6.5 - as that means you have to pay for a motor, take rotor out and buy another one. I'm not convinced this should be allowed.

From what i have been told, sintered rotors should be more reliable than bonded, but it seems that they are not 100% bomb proof. I have heard of some failing.

Never trust a man with a beard, you never know what he's doing behind there, maybe a 10th scale replica of the titanic or mixing liquid hydrogen and liquid nitrogen in a controlled manner......
