The invention relates to the technical field of speed-regulation and energy-saving transmission, in particular to a permanent-magnet speed regulator with a single permanent-magnet disc. The permanent-magnet speed regulator comprises a speed-regulating mechanism assembly, a conductor disc assembly and a permanent-magnet disc assembly which are axially and sequentially arranged, wherein the speed-regulating mechanism assembly comprises an input shaft connected with a motor shaft, the input shaft is sleeved with the conductor disc assembly including a first air gap regulating assembly, a middle disc and a second air gap regulating assembly, and the second air gap regulating assembly performs opposite or relative axial movements along the input shaft under the linkage effect of a gear and a rack mechanism when the speed-regulating mechanism assembly pushes the first air gap regulating assembly to move axially. Under the situation that only the single permanent-magnet disc needs to be arranged, the slip rate betwe
