Title:An Analytical Lumped Parameter Model for the Bearingless Separated-Stator Flux-Switching Slice MotorAuthor(s):Stefan Mallinger, Wolfgang GruberAbstract:This paper presents the fundamental principles for a lumped parameter model with angular-dependent parameter values for the bearingless separated stator flux-switching slice motor. Because finite element methods (FEM) are either too inaccurate (2D) or take too long to calculate with reasonable computing resources (3D), it is necessary to develop an analytical calculation method that gives better results than 2D but doesn’t take as long as 3D to calculate. To achieve this, first the cross section of the geometry is unwound to generate a planar model in polar coordinates. Then the equivalent circuits for a lumped parameter model are derived from it. After the network topology is defined, the parameters can be derived. They result from the defined geometry (i.e., the diameters and angular equivalents of the stator and rotor parameters). Because of the changing f lux paths due to the two air gaps, the parameters are not only dependent on the air gap angle but also sectionally defined. After the parameters are defined, the air gap field components are derived, and through the resulting air gap fields, the calculation of the single-phase force and torque components is done.Booktitle:ECCE-ICCE Energy Conversion Congress & Expo, Phoenix, Arizona, USA; 20.-24.
