According the way those winding's are connected with the capacitor, you can use that electric motor as self-actuated generator! Just clutch the axle to some engine or to another electric motor with same or more output power, set the RPM to it's nominal and you'll get the output of electric power that is 60% more than basic! For example, if your motor is 1kW, as self-actuated generator he will give you 1,6 kW of electric power!
What is capacity of that "unmarked capacitor"???
And to all of you who says that this isn't a Tesla coil, IT IS!!!! Tesla coil meaning the two separate circuits that are with same weight but different diameters of the wire, and no iron core inside!! That is the basic meaning of Tesla coil, and where ever you have this kind of circuits, you can call it a Tesla coil!!! No matter of output voltage, current or frequency!!
What is the frequency of output current??? Have you measure it???
