Establishing the relative merits of synchronous reluctance and PM assisted technology through systematic design optimization
2015
The paper describes a systematic method for optimally designing with multiple objectives and differential evolution algorithms, current regulated electronically controlled synchronous reluctance machines. A large scale study with thousands of designs calculated with a ultra-fast computationally efficient electromagnetic FEA establishes the performance limitations of conventional radially laminated technology with multiple flux barriers. The potential advantages of employing permanent magnet assisted technology with additional ferrites in the rotor are quantified in terms of substantially improved power factor, specific power, and efficiency. Numerical and experimental results for a 10hp 1,800rpm typical rating are included.
