| Summary: | The paper proposes a method of forming a numerical projectiongrid algorithm on a regular triangulation network for the
calculation of three-dimensional models of the magnetic field
of synchronous magnetoelectric machines with excitation from
permanent magnets (SMEM PM) using recurrent expressions
obtained on the basis of a «three-dimensional regular element» for
a cylindrical coordinate system. The use of the «three-dimensional
regular element» makes it possible to automate the process of
forming a global system of linear algebraic equations in the
projection-grid Galerkin method in combination with the finite
element method bypassing the stage of constructing elemental
systems of equations. When solving the problem of optimization
of designs of low-speed synchronous magnetoelectric machines
in the electrical complex, the Central place in the refinement
of the solution is occupied by the calculation of the magnetic
field. According to the known distribution of the magnetic field
in the regions occupied by the winding current are calculated
inductance of the winding, back-EMF, the performance of SMEM
PM in the high-tech electrical complex (HTEC). |
