Original Kurzfassung:
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.
