Thank you very much!!
Can you say, which exact Motor Driver IC's are soldered.
They are the 5 peaces in a row.
I remember me,
the GB203 Gimbal has
TI 8839
also the CGO3 and the CGO3+ has TI 8839
it would be very interessting which Motor Driver are soldered,
i think, this are again
TI 8839
( DRV8839Low-VoltageDual ½-H-BridgeDriverIC )
Why i ask:
I have several E90 and C23 and E50.
All them have allways the same Problem after a few time of use.
one time the 360° Gimbal do only work in one way direction, but drops in the other and then stopped it and camera goes reset.
other time the pitch motor comes in trouble and the camera goes reset,
the roll motor work was untile today allways ok.
The datasheet says, that 1.8A max drive current ..
here is a test video (other gimbal ) with few things what can be happend with the current if the gimbal get resistance ( example wind ) .. it comes very fast over the 1.8A
My thinking was then, that this Motor Drivers are perhabs have a to small dimension
but Yuneec never change the reference design to an higher IC since the work began with GB603. I think for the TornadoH920 Gimbal are perhabs same IC used ( i can look at this next time cause i get GB603 next time )
Can you confirm that the 5 IC's are again TI8839 ?
Btw: @all
why allways use (only) 5 IC's from them?
i find no logic for this.
usually one IC drives one DC Motor or one line Stepper Motor.
of course - the motor has 3 lines
so usually we need then 3 IC's of them for one motor.
so there usually must be 9 IC's
are the IC's sharing the line between the Motors?
so two Motor (lines) are connected to one IC out?
who knows detailed more things about this.
i am sure, the Driver IC's goes damaged allways cause the max current goes to high.
or the
power is not enough to driver the motor
and driver current goes higher and higher
thank you
best wishes
