The invention discloses a mixed-excitation non-contact levitation and guidance system which adopts permanent magnet and electromagnet mixed excitation, can be used for remarkably reducing the control current, is low in power consumption and can be used for non-contact guidance of a hoisting machine and an elevator. The mixed-excitation non-contact levitation and guidance system comprises a guide rail and a guide assembly, wherein the guide assembly is composed of a left yoke, a right yoke, a permanent magnet, a left coil winding, a right coil winding, a left gear and a right gear; the left yoke and the right yoke are both of C-shaped groove bodies, notches of the left yoke and the right yoke are opposite and are symmetrically formed in the left and right sides of the guide rail to form a semi-surrounding structure and form air gaps in two sides; two lower arms of the left yoke and the right yoke are connected into one body by the permanent magnet, the lower arms of the left yoke and the right yoke are symmetrically provided with a folded-line-shaped left gear and a folded-line-shaped right gear in a vertically upward direction, and are provided with coil windings correspondingly in a sheathing manner, the top end surfaces of the left gear and the right gear are parallel to the side surface of the guide rail and are provided with gear air gaps. The mixed-excitation non-contact levitation and guidance system is small in part quantity, small in occupying space and low in power consumption and can be controlled simply.
