I'm planning on building a simple induction motor for my class project and am hoping someone might have some advice about powering the motor. I feel a little ridiculous asking but I had almost no understanding of electricity prior to the beginning of my Physics 212 class and the textbook doesn't answer all of my questions.

I know that I need to be using an AC power source. I know that AC is what comes out of our wall. I know that I need a capacitor to make the current through my two inductors out of phase. I know that the average potential coming out of the wall socket is 120v and the frequency is 60Hz.

Here is my ridiculous question. How do I safely wire my induction motor so that I can plug it into the wall? Is this even the best way to power it? I thought about getting an inverter and stealing the battery out of my brother's car but is that even the best way? And if an inverter battery combo is a good idea, how do I connect my motor to the inverter?

I'm hoping this problem is as easy as I think it is.

Thank You

in advance!The best way to power an induction motor is to use a variable frequency drive (VFD). This is essentially a motor controller that converts the AC power from your wall into a DC signal, which is then converted back into AC power with the desired frequency and voltage. This allows you to control the speed and torque of the motor. If you're looking for a simpler solution, you can try using a transformer to step down the voltage from the wall socket, but this will limit the range of speeds you can achieve with your motor. Alternatively, you could try using a capacitor, as you mentioned, but this will require some additional circuitry and will not be as efficient or precise as a VFD.
