| Izvleček: | Magnetic bearings are a system of electromagnets, which makes possible contact-less suspension of a rigid body. The work presented here deals with the optimization of radial active magnetic bearings for a spindIe drive. The bearings are optimized by differential evolution. The optimization aim is to achieve a maximum force at a minimum mass of the entire construction. Predefined design parameters are the bearing auter diameter, the shaft diameter, the air gap and the minimal generated force. The dependency of the objective function on the design parameters is not known in analytical form due to the magnetically nonlinear properties of the iron core. Therefore, the objective function of each individual parameter set in the population of the optimization algorithm is evaluated by the finite element method. |
