Abstract

The rotor eccentric is a normal state when DSPM running. When the rotor is eccentric, the air gap magnet density under relative pole is not equal. So, this causes large radial force acting on rotor and stator. Which causes vibration and noise. So, the analysis of radial force under rotor eccentric is the base to reduce vibration and noise. In this paper, FEM is used to calculate the static characteristic of radial force under rotor eccentric. The change rule of radial force with different rotor position, winding current, eccentric degree and eccentric angle is analyzed. The nonlinear mapping among radial force, rotor position, winding current, eccentric degree and eccentric angle is realized by improved PSO optimized RBF NN. This work forms the base to radial force control and parameters optimization.
