New Direct Drive Inrunner 65150

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 https://www.convertunits.com/from/kg-cm/to/N-m
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.

Never blindly trust specs from Chinese manufacturers :slight_smile:

I think Peters Design is much more compelling and optimized for our specific use (High torque, low KV, low weight and easy to waterproof)

Has anyone tried this 65150 yet?

No one that I know of.

I ordered one, still waiting on delivery. In the mean, I plan to build the cad for it.

They have good reviews overall on the Alibaba site.

Anyone try their controllers?

Have you received your 65150 Direct Drive Inrunner and tested it ?

Maytech is in the game:

what do you guys think about 9nm Torque and 195Kv?

At $600 for one it’s pretty expensive to experiment and see if it might work. I think it would be in maytechs best interest to send out a test unit to one or two people so that they can review it. If it works well then they will have buyers.
The 192kv is on the high side but may still work.

Compatible with Reacher Tech figures seen above

@Eileen, what do you think ?

Some customers pre-ordered motors and I will update news when they receive and finish test.
195KV is standard KV. Other KV can be customized.

Hi Eileen. I have some big interess on you product but with 130kv. Any more info like torque and price for one piece to try please? Yould be the same torque with 130KV? how many pole?

The first 65165 motor Maytech advertised on Alibaba was the same motor as reacher tech.

I think Maytech have their motors made by reacher tech so you could probably use reacher techs motor specs as a good guide. But why buy maytechs motor for $US600 when you can get one from reacher tech for $US410.

I hope someone tests one soon.

Thanks Eileen. This first set of data is a bit disappointing.
I am not a motor specialist but the flattering 9N.m is usually given at max rpm (16380= 195x84) and max voltage (20s 84V).
So I don’t know what to expect at half this voltage value since our voltage working range is 12 to 14s (44V to 52V nominal). So it is very unlikely that we can reach the required minimum torque for a efoil use with this 195KV motor as a direct drive = W I T H O U T _ _ G E A R

So, I’m looking forward to your 160, 130 and 100KV data as the max torque increases with the KV going down…
