Neu vs Leo

[runzwithsizorz]

Neu 1515 2200kv vs a Leo 4092 2080kv. According to the stats. the Leo has a higher wattage out-put, yet I have been reading that the neu is a better choice, WHY????

"Neu 1515 2200kv vs a Leo 4092 2080kv. According to the stats. the Leo has a higher wattage out-put,..."

Not a fair comparison -


The Neu 1515 compares size-wise to the Leopard 4074 (both have 40mm can diameter ; 74mm can length)
The Neu 1527 is what compares size-wise to the Leo 4092 (both have 40mm can diameter ; 92mm can length)

Neu motors are made with better materials to closer tolerances. Power in = power out minus power converted to heat (measured by efficiency figures)

Neu's run cooler in my experience and I use lots of them - they rarely get hot. Less heat = more horsepower

Check the stats again, but not all stats are derived using the same parameters. According to a statistic [that I just made up], 37 % of all Chinese motor statistics are created using an Ouija board



Used sensibly, Leopard motors are a very good choice - reasonably priced for what you get

Thank you Tony! I can now sleep so much better. http://forums.offshoreelectrics.com/...50-Neu-1515-1Y

I also find the Chinese are very optimistic in regards to motor ratings.......Must be the conversion from Chinese measurement......
Not exactly sure how they can claim 5000 watts out of a motor running 4s, only 350 amps! Math says yes, reality says NO!

You can't compare these motors. If you do then consider the costs. For sport running I find the LEO or Turnigy a very good motor...for the costs. Also, NEU batt requirements always indicate cell count in para config....there is a reason. This really should be followed for any good BL system...easier on ESC and motor. If you cut the Chinese rating in half you are closer to a better set up.

Neu 1515 is 68mm can and the 1527's can length is 101mm,the ones i have anyway.First thing i noticed between the two is COPPER!The Neu motors have alot more.

There are two more factors for higher efficiency.
1 How much tight is the copper wire winded.
2 With what technique.

[Heaving Earth]

I feel like even the smaller neu motor would be equivalent, or better than the larger sized Leo, based on quality of parts and machining.
When comparing the neu and Leo of the same sizes, the Leo doesn't stand a chance. The castle motors are also much better than Leo IMO

The Neu motors seem to have quite a favorable following, at least when it comes to boats. So, I for one, am *assuming* their quality is superior.
Something that I'm not really knowledgeable about is the difference between the Neu's, and the Castle/Neus.

[Heaving Earth]

The castle are designed by Steve neu and made in china from my understandings. The castle are also closer in size to the Leo counterparts.
By comparison
Leo 4074 = 40x74
Neu 1515 = 39x68
Castle 1515 = 41x75

[jkr]

Castle/Neu are also good but if someone wants to draw higher amps then Neu is prefered.
The reason for this is wen the wire comes out form the stator you can draw more power.
Think that you have three solder points less!

Also a friend here has a medusa motor (the blue one) and after 200+ packs the performance is still good!

My Leos after 40+ packs aren't the same as i see.

[runzwithsizorz]

Setting aside the cost factor, I believe that most boaters would choose a Neu over the Leo. This is why, when I saw a trusted member offer for sale last night, a Neu 1515 2200kv at a really great price to replace the Leo 4092 2080kv
I was going to use, I snapped it up. I think I made the right decision, perhaps I am just looking for validation. I am still very worried about amps, and heat, for this motor will be used in a 12 pound Titan 33.
Was also thinking of buying a set of 5s batteries to try, Your thoughts gentlemen???
Believe it or not, some of us noobs are watching, lurking, and learning, and I thank you all, and Steven sincerely.

Well in that hull it's probably at its limit, but should be ok. I run both the neu and castle 1515 1y on 5s. No Problems, just start with smallerish props.

[jkr]

I want to see the result also.
My 4s1p boat is 5 pounds.

[Rumdog]

I'll run a castle/neu any day vs a neu. They perform just as well.
