Other Parts Discussed in Thread: LDC1000EVM

Hello for design my self i need to know several things

How find the voltage across the coil between INA and INB?

I can find the voltage per turn, because i choose how many turn i want.

How calculate the resistance of the coil? for find the current after that.

Thank you

Hello,

i want to know if a hollow is obligatory or benefic for the coil.

Thank

Hi,

You can use this tool to calculate it.

Hi,

In fact, it needn`t hollow in the coil, the one in LDC1000EVM is just used for installment.

Hello,

but with this calculator if the hollow is little(din little), the coil value is low.

Compared to if the hollow is big (din big), the coil value is greater.

And with your calculator if i increase the din diameter, the coil value increase too.

For me with my dimensions if i want the largest coil value. I think i need more turn possible with the largest hollow.

Thanks

Hello,

in the calculator if i increase the temperature , the coil value never change.

It's normal?

Hi,

In simulation, temperatuer only affect the Rp, you can try again, and you will notice that Rp will change with temerature.
