Overview
MotorXP-PM is a commercial version of
MotorAnalysis-PM, a popular software for design and analysis of permanent magnet (PM) motors and generators. MotorXP-PM offers much more features and capabilities, please see the detailed comparison
MotorXP-PM vs. MotorAnalysis-PM. MotorXP-PM supports different machine types including brushless DC (BLDC) motors and generators and permanent magnet synchronous motors (PMSM) and generators with surface-mounted or interior permanent magnets (IPM). MotorXP-PM combines both finite element analysis (FEA) and analytical analysis methods providing fast and accurate results, which establishes a complete set of tools for design and analysis of permanent magnet machines.
MotorXP-PM is available as a MALTAB-based application and as a standalone program working without MATLAB.
