"high-voltage custom power supply that converts 120V/240V AC line voltage to 330V DC power for the motor and 3.3V/5V/12V DC for the communications board"

When I read that, my brain flipped thinking surely that has to be a typo. Then, "he motor is seemingly custom to account for the exceptionally high rated power (stalls at 5A at 330V DC, which is hard to believe, possibly even a misprint on the motor casing)"

So if it's a misprint on the motor, they designed a power supply for something totally unnecessary. Otherwise, if it's not a misprint, that's one helluva motor
