Default Sound of big machines

I found a video that brought me back to my motor shop days.

My old boss ( RIP ) was a very smart of German fellow that had an equally sharp foreman who trained me.

The two put their heads together one year and took a wound rotor version of this exact GE frame ( a 1910 vintage design there abouts ) and turned it into a variable transformer specifically so we could test at different voltage just like in this video.

The machine we had however used the stator wired to the rotor in a boost buck connection to give us up to 1000 volts AC.
That was enough for us to test most motors up too around 5000 volts.

I still love the sound of a big machine spooling up on floor.
