Also, incandescent lights tend to show less strobe effect than fluorescent tubes because their thermal time constant is longer than the persistence of phosphors; hence some people find the flicker of fluoro tubes more distressing than the flicker of incandescent lights.

When the engine is shut down at altitude, the core begins to cool and the stator, including the static Interstage Static Seal ( ISS ), contracts at a faster rate than the adjacent rotating parts in both the radial and axial direction because of its faster thermal time constant.

Consider that the thermally current-limited components of a large semiconductor inverter are solid-state switches massing a few grams with a thermal time constant to their heat sinks of likely more than 100 ms, whereas the thermally current limited components of an MG are copper windings massing some hundreds of kilos which are intrinsically attached to their own large thermal mass.
