Design and Analysis of PMBLDC Motor

Interest has grown in the use of brushless permanent magnet motors due their high efficiency and low maintenance cost compared to conventional motors. The use of permanent magnet in electrical machines in place of electromagnetic excitation results in many advantages such as no excitation losses, improved efficiency, fast dynamic performance, and high power density. Design of Brushless Permanent Magnet motors can be intensive due to the requirement of many design constraints. Many optimization routines exist, but require knowledge of design constraints from an existing design in order to function. This project present a Radial Flux Permanent Magnet Brushless DC motor design. This Radial Flux Permanent Magnet Brushless DC motor designed meets user input specifications. In this project, the basic design equations are derived and developed the CAD program. The Developed CAD program calculates and estimates the performance.
