How to power Hoverboard motor from wall socket

Hey all,

so I need to power a single Hoverboard motor (350) Watts,
from a wall socket and I have no idea how to step 110 from the wall to make this happen. Do I have to go up or go down?
It also needs to be speed variable from a hand controller. Potentiometer type?
any help would be appreciated.

Your hoverboard likely uses AC motors controlled by a variable frequency electronic speed control (ESC). Since your asking the question you don't have the electronics knowledge to control it directly. The simplest method is to replicate the batteries output. Find a power supply that provides the same voltage and has the amp/watt capacity needed and connect it to where the battery connects.

350W direct-drive high-torque DC motors sounds like an experimenters dream!

Control-wise most of this stuff gets way over my head--but it's fascinating just the same.

Thank you for the links. I've not seen a hoverboard like that though the second article sounds like an AC motor especially since it appears to have three larger power wires connected to it. I didn't know they used DC motors now or that they could have precise enough control with a DC motor.

A DC motor typically uses brushes and would probably not be the best choice in motors.
Three phase AC motors are hot. They increase the voltage to up the efficiency and the three phase
is much easier to control.

Think furnace blowers. All the new high efficiency units use three phase motors.
