A power strut for a vehicle lift gate, has a driver sleeve, a lead screw sleeve, a lead screw and a spring mounted in the lead screw sleeve. A gear reduction mechanism and a motor assembly are mounted in the driver sleeve for driving the lead screw. The motor assembly has a magnet mounting bracket fixed to the driver sleeve and a rotor disposed in the magnet mounting bracket. An end cover and multiple permanent magnets are fixed to the magnet mounting bracket. Each of the magnets is positioned between a corresponding pair of adjacent connecting portions and contacts an inner surface of the driver sleeve, thereby the driver sleeve provides a magnetic path between the magnets.
