Informations of angle

Hello Charly,

In case of a rotational application where you want to measure 360 degrees, you need to use multiple sensors. If you are using two sensors, they should be 90 degree separated. Multi-channel LDC such as LDC161x/LDC131x is more suitable for this kind of application. In case you wish to use LDC1000, then multiple LDC1000 need to be used and should be sychronized. A target shape as shown below can be used for rotational application:

Please have a look at the reference design in the link below:

Please let me know if you have any questions.

Thank sushas!

i want to use the Sensor for motor feedback.

I don´t know, to plot the angle with the GUI.

What can i do to see this if i us the ldc1000 evaluation kit?

Charly,

Do you want to sense the position when the motor is stationary and then provide the feedback to the motor?

You will have to use two LDC1000 devices and synchronize them. The sensors need to be placed at quadrature to each other. 

What is the resolution in position (degrees) you require in the application?

Hello Suhas,

i am so happy that you try to help me

I have a ldc1000 and I use the GUI and inductance and Proximity Data to have.

but I want to have every time the angular position of the rotor.

how can I find these angles with the GUI (ldc1000 EVM) ?.

How can I modify the ldc1000 Information request about the angle get?

or how do I link the angle with inductance of the coil?

What hardware do I need?

In Which registers the inductance values are stored?

I want to have an accuracy of about 0.05 ° - reach 0.1 °.

Best Regards

Charly

My englisch is not perfect

Charly,

LDC1000 EVM cannot provide information about angle. If you want to link angle to inductance, you need to use atleast two LDC1000 EVMs and synchronize it externally. The GUI currently does not have the capablity to measure the angle. LDC1614/ LDC1314 is more suitable for angular position measurement as it has multiple channels. I suggest you try using multichannel LDC instead of LDC1000.

The reference design in the below link provides complete information on the rotational sensing design:

Please go through it. The demo will be available of TI Estore soon.

Thank Suhas,

ich werde LDC1614/ LDC1314 testen.
ich will auch mit zwei LDC1000 versuchen.
wie kann ich dann die zwei LDC1000 synchronisieren?
was brauche ich für Hardware oder welche elemente sind notwendig?
Gibt irgendwie eine video, wo gezeigt wird, wie man es synchronisiert ?
Hast du vielleicht einen Schaltplan ?

Best Regards,

Charly

Thank Suhas,

I will test LDC1614 / LDC1314.
I want to try with two LDC1000.
how can I synchronize the two LDC1000?
what I need for hardware or what elements are necessary to synchronize the two ldc1000?
Is somehow a video, where shown how to synchronize it?
Are you a diagram?

Best Regards,

Charly

Charly,

LDC1614/LDC1314 are the best devices for this kind of application.

Unfortunately, there is no hardware built for synchronisation of mulitple LDC1000 devices.
