In this project a 3HP, 3000RPM permanent magnet assisted synchronous reluctance motor was designed for pumping application. A software tool developed for analytic & FEA design of motor using EMDLAB package. The below figure shows the sketch of the motor:

The below figure shows the software:

Design Steps:
- Analytic design using object oriented programming in MATLAB
- Calculation of magnetic-loading by FEA
- Calculation of flux linkage for aligned and unaligned positions and calculation of saliency ratio
- Optimizing rotor geometry by powerful built-in MATLAB optimization functions
- Calculation of static torque versus stator phasor current angle
- Calculation of motor torque map
- Steady state simulation of motor and calculation of motor efficiency
- Calculation of torque-speed curve and efficiency map
