Experimentally Constrained Design Parameters Approach for PMSM and BLDC Motor

Abstract

This study deals with design parameters of electrical motor to provide facilities to design Brushless DC and Permanent Magnet Synchronous Motor. The parameters are declared according to the design flow chart process, in this paper additionally the important and critical parameters and terms some experimentally constrained parameters in a specific range value are highlighted with referring many references and manufacturing experiences from the motor producing companies. These parameters are including dimensional length e.g. stator inside diameter and stator slot, material properties e.g. electrical lamination steel and permanent magnet, electromagnetically e.g. airgap flux density and electrically ranges e.g. current density and rated torque per volume, they are all expressed step by step in next sections.
