Thanks to Josh Hess & His forum here: https://www.radicalcreation.com/forums/viewtopic.php?f=24&t=23
We now have a great photo comparison of:
Enertion R-SPEC 6355 -VS- Alien Power System 6355
Let me firstly say that josh seems a bit biased towards Alien in his review, he also recommends you buy their products at the end of the review & his tone used during his review seems to be anti-enertion. This is what Josh had to say;
I have had an excellent experience buying from them and their (alien) products are by far the best price for the quality you get
NOTE: Josh is wrong…
So let’s look at the FACTS!
The price of both these motor options delivered to the US for a dual drive eboard.
2X Alien Power System 6355 + Shipping to West Coast USA is approx $186USD 2X Enertion R-SPEC 6355 + Shipping to West Coast USA is approx $235USD
ALIEN IS 20.85% CHEAPER
Now let’s look at the stator size difference. Because if you didn’t already know that is what determines max power, torque & horsepower of a motor.
Josh says the Alien stator is the same diameter but shorter, it only has 55 Laminations The Enertion Stator has 70 Laminations
ALIEN STATOR IS 21.42% SMALLER
NOTE: This also means approx 21.42% smaller magnets, 21.42% less copper
So which motor has the cheapest stator cost ratio?
Cost per lamination of the Alien Motor is $186 / 110 = $1.69 per lamination Cost per lamination of the Enertion R-SPEC is $235 / 140 = $1.67 per lamination
R-SPEC Stator Laminations 1.19% Cheaper
Now let’s look at the Build Quality
Here is a photo showing the Alien motor with a bend in it. Josh said he bent it with his thumb when reassembling the motor.
You can clearly see the differnce in the thickness of the alimunim parts, the enertion R-SPEC has much thicker profiles making it less prone to deformation.
LET’S SUMMARISE THE FACTS
Enertion R-SPEC 6355 vs Alien Power System 6355
- Enertion Stator is 21.42% Larger - Higher MAX Power, Deliver More Torque & Horsepower
- Enertion R-SPEC has larger magnets & more copper.
- Enertion Cost to Stator Size Ratio is Lower than Alien by 1.19% (You pay less & get more with R-SPEC)
- The Enertion R-SPEC has a more robust design with thicker aluminium profiles.
- The Enertion R-SPEC is also chemically treated to make it water-resistant.
I have said it before & I will say it again, You get what you pay for!
COMMUNITY SURVEY Do you prefer larger & cheaper stators in your motor so you have better performance to weight ratio?
- YES, I want a bigger stator for less
- NO, I want to pay more for smaller stator
