single phase soft start
I am in need of a soft start/stop for a 1 HP single phase motor, does anyone have any idea where I can find a low cost unit for this project? I would accept new used or refurbished

why soft start? the motor is going to draw extra current until it gets to speed. at that size, it's still likely there is a centrifugal switch that shuts off a starting winding as the motor spins up. if it doesn't get to speed, you burn out that winding.
if the motor is tripping the breaker, you don't have a motor rated breaker on there. they have a larger overload tolerance exactly for this reason.
