A permanent magnet speed governor having a fixed magnetic gap. The permanent magnet speed governor comprises an outer magnetic rotor (2) connected to a drive shaft (1), and a first inner magnetic rotor (4) and a second inner magnetic rotor (7) concentrically penetrated by a driven shaft (8), at least two outer permanent magnets (3) being evenly distributed along the circumferential direction of the inner circumferential surface of the outer magnetic rotor, at least two first inner permanent magnets (5) and at least two second inner permanent magnets (6) being respectively and evenly distributed along the circumferential direction of the outer circumferential surface of the first inner magnetic rotor and the second inner magnetic rotor. The permanent magnet speed governor reduces the consumption of materials and saves installation space. |
