A Robust Approach for FE-based Analysis of Electromagnetic Systems with Hysteretic Materials

Hamed Tahanian; Ahmad Darabi

Volume 2, Issue 1 , January 2022, Pages 1-8


  Magnetic hysteresis affects the performance of electromagnetic devices, e.g., motors, generators, and transformers. However, due to complex, non-linear, and multi-valued nature of this phenomenon, its accurate coupling to Finite Element Analysis (FEA) of these devices has been always a challenging task. ...  Read More

Advances in Developing Permanent Magnets with Less or No Rare-Earth Elements

Banafsheh Mirtaheri; Hamed Tahanian

Volume 2, Issue 1 , January 2022, Pages 52-69


  Permanent Magnets (PMs) are employed in many modern devices, thanks to their unique properties. Electrical machines, i.e., motors and generators, are a major application of PMs, which produce the required magnetic field. When there are severe constraints on the weight and dimensions of the device (e.g. ...  Read More
