How about... a speaker? "







Speakers
are both complex load impedances and motors, which include
mass controlled reactive voltages.

Except when it isn't. Speaker drivers are motors and transducers;
either label transcends the "electrical network" model.

A model that includes diaphragm mass and conversion efficency
might become interesting. Otherwise, please spare me.
