What firmware version did you use? Custom from x-maker site or standard Vesc Tool firmware?
Official from vesc.
Thare is no custom firmware for HI200…
Sorry forgot to take pictures.
Here is some.
Water intake is 3d printed part that is connected to one of the chanel inside mast.
Whole chanel is filled with water and on the top of the mast is exiting by tubing to pump…
Then from pump goes to water block that is inside vesc box.
Hello.
Did you menaged to test your 66160?
Did it work?
Mine burnt agin, same as before.
Rewound it agin and flashed 6.0 firmware to my vesc.
New firmware has some optison older one didnt.
With that options motor become a beast.
Power is increased drasticly and motor dosnt owerheat more.
I did static testing, old firmware 38kg thrust with 5" yamaha alu prop, new firmware 60+kg of thrust.
Option that help solving problem with this motor is MTPA mode, IQ Target.
+60% is hardly believable. What measurement device did you use ?
What is your ESC ? Is your new option called "Phase filtering " ? (It’s too sophisticated for VESC clones not supporting FW version >= 5.3)
I could not belive it myself but scale showed that number more than once.
My frined welded jig for testing, simple steel tubing and 100kg scale nothing fancy.
No, i know phase filtering are not avalible on chinese clones.
I have makerx hi200 and MKSESC 75200.
New option is in foc advanced tab called MTPA algoritam mode.
It is beneficial for some motors.
With old firmwares motor newer worked properly.
Hello. I tried it once, then the Flipsky motor came to me.
Thanks for the info, I’ll definitely try the new options. I hope the motor does not burn out too quickly and I will have time to appreciate the increased power.
This season I am going to build a tow boogie with two outrunners and CW/CCW propellers. And also experiment with newfangled props. Therefore, entertainment with a constantly burning motor faded into the background.
Yes i understand, i also got new motor 6105 from alien power and left 66160 aside.
Friend of mine also got 66160 last yer but he was using it with different esc so for him motor worked flawlessly, reacently he also got vesc and he tryed to get it working and discoverd that with new firmware and this MTPA, motor started working better, more power, dosnt overheat anymore so i decided to try it agin…
this looks great…
What motor will you use?
Did you allredy test propellers?
can you share stl for the propeller?
MTPA stands for Maximum Torque Per Amp, which means that for a given current flowing into the motor phases it produces the maximum torque possible.
Curious to know how a state of the art motor like the @Flying_Rodeo one would behave with MTPA …
Field weakening and MTPA
It higly depend on the motor.
Not all motor benefit from that option.
My 63105 didnt get any increase in torque but 66160 did alot.
What about the amps drawn ? Does MTPA mean you get more torque for the same current ?
It would be interesting to know which 6374 on MTPA behaves like under steroids… while preserving the battery Wh so maintaining the same riding distance …
We need a wiring expert to explain which motor can beneficiate from MTPA and why…
Realy dont know i didnt get in depth anlasys.
But you are ona good track.
I will check next time im gonna test.
MTPA is giving benefit for interior permanent magnet or ipm motors, not on common rc motors with surface magnets (12slot 14pole outrunners of any size or brand like 63100, 6374, 80100 etc)
The ipm motor is surprising in the way that it can benefit from not having the angle between the magnets and coil fields at 90 degrees (often referred to as having field weakening or d-axis current)
What MTPA control does is that it controls the field angle to an optimum for each rpm.
I doubt the increase mentioned here comes from the MTPA alone since rotor needs to be designed for this type of control to get such a large increase in torque with MTPA
Yes that is true… Dont know reason whay this 66160 benefits from this but it benefits…
You can experiment yourself if you want.
It is not only increase in torque, motor runs coler so i hope it will run without burning up agin.
I’d guess it’s an ipm motor, have you got any pics of the rotor? Are the magnets embedded in steel?
Here is photo taker by rttn, mine is same, and magnets are on the surface under layer of carbon and epoxy
Hard to say anything based on this picture, any signs of steel laminations in the rotor? any signs if the magnets are visible on the surface or embedded inside the steel? It seems thoroughly hidden
