Direct Sequence Spread Spectrum Technique with Residue Number System

design of SRM The Mathcad programs were saved as version 6 files from version 2001. Since no special features not available in version 6 were used it is expected that they can be run by Mathcad 6 or later. Flux.mcd A program to plot the SRM’s flux linkage curves. Torque.mcd A program to plot the SRM’s static torque curves. Motorsim.mcd A program to simulate the SRM running at constant speed and driven from a constant DC source. It assumes the SRM phases are independent and simulates one phase for one cycle. It assumes the torque and current for the simulated phase is equal to that for all of the other phases with the appropriate time shift. It predicts the performance of the machine and inverter calculating such things as weight, power out, power loss, and phase current.
