What external factors interfere with electromagnetic coupling? [Copy link]

The stator and rotor in the rotary transformer transmit signals through electromagnetic coupling. Who knows what external factors will affect the electromagnetic coupling?

Can external factors affect electromagnetic coupling?

The outer shielding layer of the transformer will induce current in the shielding layer, forming an opposite magnetic field to offset the influence of the transformer leakage magnetic field. If used in high-frequency applications, the strong leakage magnetic field will induce voltage in the input and output loops, making EMI worse.

“What external factors affect electromagnetic coupling?”

The factor affecting coupling is mainly the air gap of the core, which is affected by temperature changes.

I guess the original poster wants to ask what external factors will affect the accuracy of the resolver, rather than what factors will affect electromagnetic coupling.

This factor is old, I am afraid it is too much to say
