AB  -          Synchronous Machine Winding Layout & Flux Animation ToolThis paper describes the development and application of a tool created in MathCAD® to illustratethe internal workings of a synchronous machine on video. Upon receiving a set of parametersand preferences, the tool creates an interactive animation of the currents, magnetic flux, andphysical rotation of the machine. The tool even recommends the best settings to obtain a moviethat loops to simulate continuous rotation in a fast or slow motion. This enables the student tosee what a finite element program might reveal about an synchronous machine but requires onlythe same MathCAD® readily available on a university-wide license.The program has an attractive level of sophistication. For example, its inputs are the following:physical dimensions, number of poles and slots, air gap width, frequency, positive and negativesequence inputs, appropriate motor or generator sign convention, power and torque output,resistances, reactances, simulation time and time step, and calculation density. The tool thenbuilds and displays an appropriate physical cross-section diagram of the stator created from thegiven dimensions, showing a correct number of slots with their windings properly pitched. Itcalculates a complete lumped parameter dq model, displaying its particulars on request. The toolthen creates the rotor from the given dimensions, a rotor with windings appropriately placed,pitched, and skewed. The rotor has a calculation burden appropriate for the animation.The program calculates flux linkage, illustrating it as an animated distribution of arrows similarto the manner in which finite element programs show this. The density of the points for fluxlinkage analysis and the information that their arrow distribution shows is another option, basedon assigned permeabilities and calculated topology. Calculations are based on a Biot-Savartmodel of the magnetic, consistent with Maxwell’s equations. The program updates these withevery time step as the machine rotates. A plotting algorithm, specially developed to illustrate theresults, shows an animated illustration of the machine’s currents, magnetic fluxes, and rotation.The tool calculates a companion phasor diagram to help explain the machine’s state and theinteraction of its voltages, currents, and lumped parameter model of internal behaviors. Thisanimated. phasor diagram can be displayed next to the animated cross section illustration of themachine. Animation controls, like all inputs and controls, are available on a graphical userinterface.The tool is intended not to replace finite element analysis, but to provide an illustration ofappropriate results gained at no extra cost to the student who is already using MathCAD®. It isappropriate for use in classroom and instructional settings. In presenting this paper, we willshow the animation, we will provide assessment data from use with students, and we willprovide a link for download of the tool.
