This paper presents magnetic levitation test results of the time-divided torque and suspension force control type bearingless motor. The motor structure, principle of the torque and suspension force and control strategy have been conducted. The torque and suspension force have been simulated by Finite Element Analysis (FEA) using a machine model. As a result, it is estimated that the rotor shaft is...
This paper presents magnetic suspension characteristics of a bearingless brushless DC motor. The winding distribution, the principle of suspension force generation, and the magnetic suspension control strategy have been proposed by the author. The rotational torque and suspension force have been analyzed by finite element method (FEM) using a machine model. A prototype bearingless brushless DC motor...
