New Direct Drive Inrunner 65150

I would be interested in this motor for a starting point in a build. I had been waiting for VEFoil as a crowd supporter but it seems the price will be more than I am willing to go with and building my own will be more satisfying. So, count me in as one of the min of 10


I would be interested in one also…

Unfortunately you need to purchase around 100 to get the price down to a sufficiently low point!

Keep in mind this motor is not waterproof. Splash waterproof as they stated in communications along with the need for you to seal the wires yourself. Seems like not so good all the sudden for 460$ Including DHL shipped.

Would you have extra information ? On the first link given by @Jezza, the product title is " Reacher Tech completely waterproof D65L150 Inrunner 5000w". I looked carefully for the “Splash Waterproof” and did not find it. Sure, the sealing needs to be done carefully.
They manufacture ESC’s and seem to sell the matching speed controller which might be a good surprise.

When you compare both series side by side, you are not sure that so little volume (65x150) and so little power (5KW) can pack so much torque ? The torque of the 65x150 inrunner is twice higher than of the 83x95 outrunner… :thinking: … with same motor volume.

More torque then a tp100?

I am a bit septical about this Numbers , but i am not saying it will not work , the price is closed to a 56104 geared …

This was in earlier

Just in, seems to be waterproof now after sealing the wires yeah. Little concerned about the waterproof not waterproof… & the m4 bolts that secure it to the pod. I would prefer m5 for durability.

I used 4 x M5 on my last pod. If they have used 6 x M4 it will be just as good durability wise. I think this motor should work well. If one person takes the jump and it works, I can see many more buying motors.

I sent an inquiry as well with a few questions.
Customer service says the Motor is IP68 waterproof.
I’m still trying to decipher some of the weird sentence structure, but if I understand correctly the bearings are also waterproof (or at least sealed so that they don’t come in contact with water) but no thrust bearings are used.
He also mentioned “Shaft is waterproof with oil seals”.

For direct drive if deep groove bearings are used i dont see the need of a thrust bearing, correct me if im wrong

I look forward to reading real-world experience if anyone buys one. I’m pretty much at a dead end for now with my PM build due to shaft seal leaks so it would be awesome to jettison that back half of my drive! The seller should provide a free or heavily discounted sample to one of us as if it really does work they will easily sell dozens more.

The torque they stated above is just not correct. It`s only about a quarter of that given above…will be not enough… or only if you burst a lot energy into heat at your ESC…
Got better graphs of this motor:

I suppose you refer to the following table:

RT Motor D83-325 D83-270 D65L150-100 D65L150-80
Max Torque 105kg*cm 115kg*cm 115kg*cm 120kg*cm
Max Torque (N*m) 10.5 11,5 11,5 12

The second line is mine and was later confirmed by
So the possible errors can only come from … Reacher Tech.
Can you confirm you got this new graph from them ? I can’t read the horizontal line unit (abscissa) so I have difficulties to figure it out …

Yes got it from them…

Here is the data I got from them, hope it’s readable. They testet this motor with max.52 A.
Someone has an idea what the torque looks like from an SSS56114 at those Amps ( paired with 5:1 gear). Max. Amps continuous is 100A.


for the sss geared i would say something around 12nm with still a good efficency


That’s interesting. The 100KV motor is actually capable of 6KW input power so should in theory be able to produce more torque.
