Measuring inductance of motor coil with low Q factor
I have a motor coil that I suspect has an inductance outside the nominal range. I wanted to use a Maxwell-Wein bridge to determine the inductance of the bad coil. The main concern I have is that, as I ...

Help measuring inductance of custom-made coil
I am testing some coils that will be used in a resonant circuit as antennas for very low frequencies (<100 Hz). The coils work great, but the only way I have to tune is trial and error.
If I ...

Measure Delta wound BLDC motor inductance and resistance
I'm using a VESC motor ESC to drive several different motors. When I connect a new motor, it has the ability to detect the motor parameters, but somehow gets it wrong for some of the larger motors: ...

What types of inductor cores exhibit magnetization?
My understanding of magnetization in core memories is as follows: a bit is written to an inductor's core by magnetizing it, by applying a large current. Later, the bit is read by observing the effect ...

Measuring CCM Boost PFC Inductance
I have not done this measurement before, so, I would like to ask for help setting up a test to measure the boost inductance within a 3kW CCM Boost (thought I would say it again...) PFC.
Some ...

Sense small variations in inductance in AC for a metal detector circuit
I am currently working on the design of a metal detector circuit. I am relying on the method that the coil's inductance would change when a metal is close to it (due to eddy currents.) I have tried ...
