Neu 1527 Eagletree log?
 
Hiya. Was wondering if anyone have any reports on the Neu 1527 line of motors. I was most speficially looking for the highest rated watt numbers on this motor. Website states up to 5000 burst. Anyone gotten it that high?

I've hit 3600W:

I was basically doing speed runs up and down a soccer field without giving it any time to cool down and motor temps stayed under control. I imagine this motor could handle more power, just haven't had a chance to try.

Very nice. So you feel that there's more power available?

CC/Neu lists it at 5000 burst, so it should be able to peak around that number.

Oh, and what voltage is the motor rated at max and what are you running?

Neu rated the 1527 @ 4500W surge. I'm glad that this motor is able to push that kind of power, especially since I have 4 of them. I will post up some graphs of the 1527 running my 18Lbs GST. It may push it to it's limit.

Does the Mamba XL log current/voltage?..

Yes it does:yes:

Nice. I saw some pics of your GST garage with the Neu 1527's. Impressive. :)

Good info
 
This is good info since I picked one up from James a little while ago. I have yet to use it, but I am sure that it will be a great asset once it is installed in one of our trucks. I really had no idea that it was that powerful.

The 1527 is rated at 5000w and will take it - I have run mine at 4200 watts on 6S however this is water cooled. C

Check the formula for calculating the power the motor can use. The amp levels you can use will vary with the voltage and the wind. However for more voltage and motor resistance the aount of current you can draw falls

Eg on 10 cells run a 1.5Y over 130 amps and it will fry

Ere on the side of torque ie lower Kv and use more cells - not only will you have huge speed and acceleration, much harder than any current rc tire can deal with, your runtimes will be better than guys who went for the amp hog motors

That's around 6-7 HP. Incredible what these electric motors can dish out. Also an incredible leap from the brushed motor standard some years ago.

I quit RC when brushed motors was the only thing on the market (As far as I know.), and came back to the brushless standard. Quite a massive leap in technology. There are also other forms of electric power though, but what is more powerful than brushless? When will it come out? Anyone know?

You're correct, don't forget to calculate the efficiencies. The 1.5Y supposedly only good for ~65 Amps maximum, whereas the 1.5D is good for ~113A according to Neu's Spec from their website.

Brushless dont make any power -but they are efficient converters. For more power processing go to a larger motor. The Neus are as good as it gets outside the truly exotic and mega buck solar racer motors. Others will catch up.

The batteries make power and there seems to be no slowing in the pace of development there. And they have about another 30% of current power to go before they get to thepractical limits of lipo (cobalt) development.

Especially in cars motrs are often high rpm and current hungry. This means their max efficiency is outside or toward the upper reaches of the power systems operating range.

Cars might spike to 3500w BUT 95% of the operation will be under 30% of that figure so its a good idea to work that into motor selection, then you will have quite long runtimes as well.

Also cars use 36-40mm motors but by far the best (torque) Neus for cars IMO (lower voltages) are the 1900s they are very light and very effective and deliver excellent power to weight figures for the model and they are cheap!

Sparky, if you want the most Wattage out of the motors... How many cells do you plan on running first of all?..

Don't forget about the ESC.. :mdr:

That's why it is so crucial to have the proper COMBO... Battery, ESC & Motor. I haven't pushed my 1527 to the limits yet, but it is a powerful motor in an 1/8th scale vehicle.
