| Zusammenfassung: | A governor for a moving device, such as an elevator, includes a primary assembly that generates a magnetic field and a secondary assembly extending through the generated magnetic field. The assemblies define a rotor and a stator that rotate at a relative speed that is proportional to the speed of the moving device. The stator is biased into a stationary position. If the relative rotational speed exceeds a predetermined limit, the bias on the stator is overcome by the interaction of the secondary assembly with the magnetic field. Movement of the stator away from the stationary position actuates an apparatus to prevent an overspeed condition of the moving device. |
