I am interested in powering an 1800 watt airplane DC motor with 120VAC at <15 amps, so basically straight from the wall.
How do I deal with the ESC and possibility of hitting 60 amps with the motor?
What else should I look into?
This is the motor I am interested in
I am an aerospace engineer, so I understand the basics of ac and dc.
And I know it cant be powered straight from wall. What i am asking is are there products to convert ac to dc that could handle this 80A motor
Slipstick, thank you this is pretty darn close to what I am looking for. I need to be able to adjust voltage to control rpm. Would this work the same way with an ESC basically replacing the battery

Wrong way round. A standard RC system with a brushless motor goes Battery > ESC > Motor. The power supply replaces the battery. You still need an 80A ESC because brushless motors do not run from plain DC. They need the ESC which effectively replaces the commutator in a brushed motor and it's the ESC (Electronic Speed Control) that controls the motor speed.

Yes, that is what I meant to say, was writing it from my phone and either worded it wrong or missed a comma. Thanks a lot for the info!

This is about the most dangerous suggestion I've seen.
It is not a DC motor, its a 3-phase BLDC. It needs 3-phase drive of about 20V to 30V max, with
active current detection and control.
It is not rated for mains in any way at all. It has a winding resistance of 0.02 ohms which would
in theory blow most of the fuses between you and the street mains simultaneously as it explodes in
your face.
A 20V 60A BLDC motor is not a mains 120V 15A motor.
