My first prototype, no switch, three capacitors

UpUp


The very first try was quite simple. I spun the motor by hand and then applied power. No capacitors. The motor was finally able to accelerate, after much difficulty. That proved to me that it was not "fried".

My first prototype was simply a test of the concept -- would a three phase motor spin up like they say, if I apply capacitance between one power leg and the generated leg?

I wired the motor as follows: two legs of 240V were connected to the two legs of the motor. These I call Leg 1 and Leg 2. Leg 3 was connected to Leg 1 via three capacitors wirted in parallel. You can see that on pictures.

That made the motor spin up reliably, but slowly due to very poor contact between my wires and the subpanel. After that, I decided to try better wiring. See next chapter.
