VIRTUAL CURRENT REPRESENTATION OF MAGNETIC FIELDS FOR ELECTRIC MOTOR DESIGN

A computer-implemented method for simulating a magnetic field within an electromagnetic device for use in evaluating the electromagnetic device. The method comprises: obtaining a digital design of the electromagnetic device, the digital design comprising geometric data representing a geometry of the electromagnetic device and material data representing material properties of the electromagnetic device; obtaining magnetic field data representing a magnetic field pattern that would be generated through operation of the digital design of the electromagnetic device; and converting the magnetic field data into virtual current data, wherein the virtual current data represents the magnetic field pattern as one or more virtual currents that would create an estimated magnetic field pattern that substantially matches the magnetic field pattern.
