Yep that seems to be the case. I obviously had no way to test this since mine is an older unit but I bet someone could make it work since the "Robert's Mod" Motors do have a shaft sticking out the back. Would love to hear if someone out there got that to work.

Nice one Mark, great coverage of a very important topic now Flight Sims are in the picture for these motion platforms. DOF Reality initially had a poor reaction to a legitimate issue imho but if they can deliver on improvements then people will appreciate that in the long run. Personally I think helicopter flight is the right test for comparison if you get a chance before dismantling the mod…

O' I've been flying the Dune Ornithopter and it is a blast. The motion is good, I just hate how loud the motors are. That is far more immersion breaking to me than the little cogging ever was. I agree the DOF response could have been better but I see them as having tried various things to fix it... that was why they went to the SFU, then the higher resolution sensors, etc. I just don't think their messaging matched what their efforts were and that is unfortunate. Hopefully they are on the right track now though. Thanks for the comment!

Less punch = Less maximum torque! So easy to explain dude! Those new motors are smaller, (Typically means less HP and torque IF similar winding designs are employed.) AND with the added gearboxes that increase speed output with a proportional loss in motor torque; PLUS add in additional mechanical losses from the gearing itself= No equal to the original motors! Plus the gearing are likely the cause of the majority of the whine you hear too and they will wear out at a much greater rate than the original stand-alone motors! Furthermore; the smaller/lower speed motors have more magnetic poles around the 360 degree axis which breaks the torque pulses into smaller radian per pulse reducing the perceived cogging to smaller increments. Also the reduced torque smooths out the cog making it less previable to the user too. I would be willing to bet if the manufacturer added "S-Curve" ramping to both the acceleration and deacceleration time profiles plus add it to the starting torque profiles, the cogging would be eliminated via software adjustments! (Done this type of adjustments to thousands of industrial machines and people movers for the last 30 years!) Not sure what firmware additions they can add to the customer software or at the Arduino axis controller itself to achieve this type of adjustable settings. The Arduino controller is a great low cost axis controller but has tons of limitations compared to conventional industrial solutions that frankly are too expensive to consider for this market. In conclusion: This motor alternative is just a bad idea all around especially for long term reliability! (Do some heat checks on these motors and gearing after 1 hour of dogfighting in a WWII aircraft and you will see what I mean.) Like you said, a commercial pilot simmer would be fine as long a you can stand the gearbox whine from time to time and maybe worn out gearing some time down the line.
@GYGOtv6 ай бұрын
WOW, thanks for all the details there. Your comment is WAY past my pay grade :) Appreciate the detailed explanation, it was my understanding that the Torque was similar with these motors but again I'm just going by what I could find online. I actually almost followed most of what you said and would actually appreciate talking to you more about this as I want to do a separate video on what causes the "cogging" in the first place. I personally think the torque ripple (I think that was what I heard it referred to in the videos I analyzed) is a major issue for this and I hadn't thought about having more poles in this motor but that certainly makes sense. Anyway thank you again for such a detailed comment and if you don't mind I might bend you ear on more of this stuff later.

My pleasure, always available sir! (Retired early from industrial automation and robotics to take care of my ailing mother out in the rural mountains vs a retirement home.) Some day I'll have a DOF unit but still working on updating other components first on my newly fixed budget. (Considered making one myself but more work than I have time for these days. Plus I am not a software/coder guy and would need help on that anyways.) Torque ripple is another phenomena usually created by the DC Drive controllers and their specific type solid state device switching characteristics and settings. (Another possible issue here but in my world adjustable to smooth this out and be non consequential. I would guess the DOF DC motor controllers has very limited adjustability too.)@@GYGOtv

Actually the gear motors are more powerful than the originals including the P motors, 10kg torque. The issue with any lack of response can be tuned out with SRS as has always been the case. Having to change mutilple profiles is a PITA but it is what it is. I completely understand how someone with a ton of profiles already saved would shy away. Longevity is an unknown but the gears are solid steel so they should last a long time. As far as the added sound, yeah that can be an issue if you're running more than 2 or 3 of these motors. I designed this mod for the H3. These particular import motors, like the originals, are all made in China, no surprise there. It's the 4.25:1 gear ratio built in to the motors that multiplies torque.
@bakzetary31456 ай бұрын
There is no way those smaller motors have more output torque than the originals, period. (I could go on in great detail to explain why but a waste of time at this point.) By the way, where did you get the rating? From the manufacturer ONLY I would guess? Does that include the attached gear-box? Most these foreign motors, especially from China are grossly overrated from reality, 50-100% greater than reality to be frank! If it doesn't have a UL/ETL EASA rating label, the data you're getting from the manufacturer is complete fiction! Steel gears is a bare minimum, but hardened surfaces would of been better also with helical bevels. These boxes whine like they are cheap-straight cut gears right out of China!!! @@rnlcomp
@rnlcomp6 ай бұрын
Yes actually they can and it's due to the 4.25:1 ratio the gear boxes inside the motor. Dof's Chinese produced motors are nothing special, just regular old 24v dc motors. You may know a lot about motors and such but you obviously know nothing about these specific motors or how size don't mean squat anymore. No I'm not Chinese nor am I affiliated with the company that sells the motors. If you doubt what I say, give the mod a try for yourself. The "Less punch" description is misleading. I would call it lag. More like the delay you get when you plant your foot on a turbo charged car as opposed to a non turbo car. However that can be tuned out for every vehicle profile. That is where people would be basically back at square/day 1, like they just got their rig and had done no tuning at all. @@bakzetary3145

Great video, really appreciated. I have a H3 and to be candid have been dissapointed, mostly due to this issue which I had no idea how to describe or fix. I play DCS mostly, but do a lot of A2G and when trying to get the pipper on a target the cogging is very noticeable. It feels like you make a tiny movement and nothing happens then another and all of a sudden the platform lurches. In dogfights or car racing I didn't feel it as the movements are more pronounced, but it is a real immersion killer on fine movements. Mostly this is for roll and pitch so I was wondering if you could just replace those two motors? I also just read another comment about it not being suitable for the 'newest' platforms, how do I know which one I have? I ordered mine in late August 2023.
@GYGOtv2 ай бұрын
Thanks for the comment, appreciate you watching. So yes you only need to mod the main motors, yaw doesn't need it. The way you tell if your H3 is old enough is see where the encoder (sensor) is mounted to H3. If it is on the side of the gearbox you can do this mod (you can see it on the thumbnail for the linked video, you can see the black cord running to it... kzfaq.info/get/bejne/jMpllKafqay2iX0.htmlsi=ldRkvUxuI_cruk0B ) If however the sensor is mounted to the back of the motor then you can not use this mod. If that is the case, all is not lost... You can try adding a transducer (like a butt kicker) to "mask" the Cogging. This works for me and greatly reduces that studder feeling when I play DCS. Hope this helps, let me know if you have any other questions.

I am planning on purchasing a P3 or P2 motion platform. Did DOF Reality give any hints as to what their proposed solution may be? I would rather hold off on purchasing if they are looking to release a new version of the platform that reduces the impact of cogging. I only fly GA, so I am a little worried about the experience I will have with the current platform. Both you and Steve (VRFlightSimGuy) seem to say that it is not as bad as people make it out to be, but then other regular people of the MSFS forum complain saying it is the worst immersion breaker. Any insights would be appreciated!
@GYGOtv5 ай бұрын
Hey Thanks for the question. SO first off you don't need a P-Series unless you are going to run it in a commercial environment so save your money there (plus we have a 5% discount code in this video that should help as well.) In my opinion the "cogging" is way overblown in the community but I can understand it bothering some. It only happens when you are in very slow turns but it is there. It doesn't bother me because I have a Buttkicker transducer that adds engine/prop vibration to the rig and that pretty much masks the cogging effect so I hardly notice it. BUT if you want to wait, they say they are working on a fix, Steve has some new shafts but I don't think they will be enough to totally remove the cogging IMO. I think we will need new motors to be honest, and I bet DOF Reality will try everything else before they do that. I think some more powerful motors with helical cut gears (to reduce the noise) will end up being the answer, unless they can come up with a way to implement stepper motors at a reasonable price. Another option you could consider would be a PT Actuator style rig, it will be super smooth but will probably cost you about twice as much, you don't get as much movement out of it but the GREAT thing about going that route is you will get Heave which is awesome when you land... you feel the plane hit the runway, which I love. Hope that helps, please let me know if you have any other questions.
