Here's a grocery list for a few drives. The BOM was posted for the Komar! A totally embedded state of the art FOC SVC drive!Now a genius could have asked me for the GERBER files and got a board house to supply them with the 8 layer pcb ready to accept Pavels brain. But they are not ready for anything different than epithet or a 20 year old inverter with turnigys basic brain for hobby king.
make it make sense......not a single competent hobbyist needs me to show them a thing to put this fisher priice puzzle together. All the hard stuff to built the drive has already been done for brilliant trouble makers on WWW forums. Who's fault is it if you the subscriber doesn't execute? Don't get mad at me.... that's your own fault to each and every man.

H-bridges 101
A common use of the H-bridge is an inverter. The arrangement is sometimes known as a single-phase bridge inverter.
The H-bridge with a DC supply will generate a square wave voltage waveform across the load. For a purely inductive load, the current waveform would be a triangle wave, with its peak depending on the inductance, switching frequency, and input voltage

Thats what so nice about the AJ here before the thermally conductive potting wound on the factory iron untouched. It has more copper cross section in the slot than the 500 euro competition Black Kontronics 650's and they don't get back cheap bearings the use in them either....😛
Andrew Jesky sees about 400 mah less in his program with it than these programs he flew with and it flies in his #1 on a VLV contra drive
Andrew Jesky
His F3A accomplishments are as follows:- 7-time US F3A Nationals Champion
- 8-time US F3A World Team Member (2007-2023)
- 7-time US F3A World Team Captain
- 7-time Finalist and Top 8 finisher at the World Championships
According to Contra Drives and Andrew it equated directly to about a 10% increase in empirical efficiency

I currently have 4 650's and 3 600's here on the table awaiting the transformations. But first I must receive all the new bearings for them. Some pilots request the UDL treatment with is 15 dollars additional for each bearing. It increases the load capacity and protect the bearings in the absence of grease.
A precision Torx set is a must. Some of the stuff you see is real trash with soft tips. You cannot do anything with it. I may just go for broke and purchase an entire set of precision drivers from WIHA
Have fun with the pyro 650s copy cat. U know you're a scorpion man....

I think his 3d planes run egodrift which I am to wind one but will not highlight Vicent's motor because he did not keep his word about a raw stack 5040 meaning i have to buy one and tear it down to rewind it. He claims he doesn't want to be part of the proxy war but yet obviously he does that's why he doesn't give me the stack he promised on the open forum . Its silly! why not let me buy a raw stack at retail.....
hatin...is all that is.

For speed pilots here to defeat the rising eu and international prices. I plan to build a series around the 53 and 41 series Cobras from the USA. The body of the motor has excellent axial cooling and incredible room for large winding heads and connection variations so you can really fill the bobbin, plus they are 14 poles. My new cuts will be made to fit these not a European scorpion or kontronics. The price is gone be too high. I also dont see the point in using a heavy bell redesign of a motor made specifically for a heli for cooling with radial air flow

You get what you ask for. A Black Composite Cobra with full intent to strike!
Thank you

Also do not forget that the competition series of pyro gives you also custom engraving, so that part is nice. Wonder would Kontronics for a fee offer the engraving service for a standard red cap motor.Originally posted by Clugh View Post

In the meantime im back to the inverters hi side logic PCB. I didn't find a footprint pattern model for the Mitochondrik LV IC from zubax so I built one based on its dimensional sheet. The CAN transceivers and powers supplies need to be added. Then your connectors and UART via usb C. You also have your indication LED that have to be added as well. I plan to have it and the power stages all stacked on top of a power supply board with about 4700 microfarads of MLCC capacitance. Thin and compact. I have to amend the current sense stages for more accurate measure.

The Germans are building.....I can supply excellent BLDC power systems for these beautiful wooden planes that fly in excess of 400 km/h. Its more to it than just a motor rewind. If the boys want to build one they can definitely find word class power for it on the west side. I'm ready to support you flying faster. You can believe me!!!

Hi,
Does the speed clan all remember this suggested ALPHA 60A 12S V1.2 Multi-Rotor Drone FOC ESC that touts "high efficiency" ? I want you to look at it beside the MYXA which is a 12S lipo 1200 watt inverter with the mitochondrik LV at heart using Talega SVC FOC FW.
The T-Motor Alpha 60A 12S was tested side-by-side with Zubax Myxa A0 to compare their energy efficiency and response linearity. This post summarizes the results. The test was arranged as follows: motor T-Motor MN501-S 240KV with foldable propeller T-Motor 22.2x7.2 installed on the RCbenchmark 1580 dynamometer.
"The higher efficiency of Myxa is critical not only in energy saving but also in mass reduction. This is because the reduced heat dissipation — achieved through the superior motor control technology that is among the best available today — eliminates the need for massive heatsinks and bulky enclosures thereby reducing the mass of the airframe and saving valuable space onboard. As such, Myxa is almost 2x lighter than the competitor, more energy-efficient, and does not require a heat sink to deliver the required power output.
Since this drive is intended for a multirotor vehicle, the time constant of the velocity response is critical. To meet this requirement, Myxa has been configured to operate in the INDI velocity control mode (INDI stands for “incremental nonlinear dynamics inversion,” an advanced adaptive velocity controller; learn more from the Telega Reference Manual). INDI provides a fast and stable response that outperforms competing technologies (such as feed-forward PID or fuzzy controllers); this is especially critical for multirotor vehicles. This mode provides a very linear velocity response irrespective of the battery voltage and propeller velocity, enabling highly robust attitude control"

Do you still want the T motor inverter?

According to Ralph
"The YGE 120 is my favorite LV ESC: It hat(ed) btw. the hardware and software on board, like the 160FAI. That's why it can do much more than it says on the tin, if partial load is not required.
By the way, the same was true for the 18 and the 30 - only Kondis and cable were designed differently.
((https://www.kleinanzeigen.de/s-anzei...68828-249-5472 you could get softened.......))
PS.: Why more is called for the P600 at K than for the P650 is also not clear to me."
I'd leave the old and used YGE 120 or 160 in Germany as far as I'm concerned because the entire line of antiquity has the highest resistance in class bro.. That's the limit of its power not the wires or the caps. Also drive with dated logic and hardware. Not even YGE recommends their old stuff....
Review the drive specification data bases in E calc. There you can see how it compares to the other drives in its class and price range.
An APD 120 F3 will laugh at the old thing. You might win a few playoff games but never the Superbowl if the right equipment competes beside it.
No one will like a drive better than one they build themselves that laughs at an 15 year old YGE who's part load cannot touch a Kontronik drive.
Its 2025.and even scorpion builds a more powerful drive than those fossils fuel bricks.....
Ralph!
The drive is so old it still lists Nickel metal halide and Nickel cadmium batteries for battery compatibility.....
be real... why push a drive that's practically obsolete....

So much for quality precision. Kontronics has a gorilla putting the shaft collar set screws on. LOL! Back to the drawing board at least it had bite obviously but the steel is trash so I'm sorry China failed this time. ☹ All my fault. I got what I paid for when the complete set of 10 was less than 20.00...
Cheap is as cheap does. The WIHA set I posted is 300.00 😏
I guess you could put a soldering iron on the collar to break the Loctite bond on the TORX grub screw. I'm assuming that's the deal with it. If it stripped id turn to a left hand drill bit to get it out and put a brand new collar on it. I ordered a lot of collars and 6mm x 500um shims some time ago. I can take up any axial play with the shims but I think ill order some wave washers because the preload works well and does allow some axial float which I believe the magnetic coupling prefers a little freedom
Thank you
