Disturbance in the Magnometer

Started this discussion. Last reply by Richard Boyhan Oct 1, 2013. 2 Replies

I have 4 motors that are causing a magnetic disturbance in the magnometer. I wanted to know if there was a way to compensate for the disturbance caused by the magnetic field of the motors. I was…Continue

I have the APM 2.5+ with telemetry and GPS units. I have a 6 channel receiver and a radio controller. I have channels 1-5 connected to inputs 1-5 of the ArduPilot. I am planning on using it on a…Continue

"If you're compassmot returns over 30% and you want to get it down, you need to move your amp away from the magnetic source. Most people move their amp higher up on the stack on their quad frame."

"Run Compassmot. Go into your Terminal window and connect the APM. Type Setup and hit Return. Type Compassmot and hit Return. This procedure relies on you spooling up your motors to 50 - 75% for several seconds. Best and safest way is to remove all…"

Disturbance in the Magnometer

I have 4 motors that are causing a magnetic disturbance in the magnometer. I wanted to know if there was a way to compensate for the disturbance caused by the magnetic field of the motors. I was thinking of using the COMPASS_MOT_X, COMPASS_MOT_Y, and COMPASS_MOT_Z to compensate for the disturbance.Is there any way that I can get rid of the disturbance in the magnometer due to the motors' magnetic field?See More

"The conversion is done by different formulas within the APM code. PID Controller Design -- This is a good site to get you started into the world of PID controllers, which is what the APM uses to do the conversion. I'm not sure what…"

"Ok, I will try arming it first. I have calibrated everything and it is ready to be armed, I just never actually armed it yet. I just wanted to make sure that I would get a valid signal before I connected the motors. I was using a Servo because I…"

"The APM won't drive its outputs to anything but idle until you've passed the pre-arm checks and successfully armed it.  I'm not sure why you're doing what you are but you're pretty much wasting time by connecting a…"

"Yeah, I used a separate power supply for the outputs. Although, when I connected the oscilloscope, I am still getting a 500Hz signal. "

"If I understand you correctly you are asking "how" the conversion takes place? OR are you asking for the exact spot in the code that conversion takes place?"

"Are you powering the servos with a alternate BEC? The APM cannot support the amp draw required by the servos."
