要約(日本語): One degree of freedom (DOF) Bearingless motor uses circular permanent magnets on rotor and stator for suspension of rotor in the radial direction, but the rotor is unstable in the axial direction. To achieve stability of magnetic suspension of rotor, PID feedback control is employed. The derivative controller amplifies the noise of higher order frequencies and causes instability. To suppress amplification of noise from the analog to digital converter data, discrete low pass filter is employed. In this paper, the selection of discrete low pass filter function, it’s implementation in c-language and experimental results of the achieved magnetic suspension of rotor of one DOF Bearingless motor is presented.
