Design Optimization of Synchronous Reluctance Motor for Reducing Iron Loss and Improving Torque Characteristics Using Topology Optimization Based on the Level-Set Method

IEEE transactions on magnetics, 2020
Because the synchronous reluctance motor (SynRM) does not require a rare-metal-based permanent magnet (PM), the demand for SynRMs is progressively increasing because of the inexpensive design.

Fast Iron Loss and Thermal Prediction Method for Power Density and Efficiency Improvement in Switched Reluctance Machines

IEEE transactions on industrial electronics (1982. Print), 2020
To effectively find an optimal solution in the development process of electrical machines, it is essential to predict machine iron loss and thermal behavior in the predesign stage.

Losses in silicon-iron

IEEE Transactions on Magnetics, 1974
Measurements of total power loss and domain-wall spacing have been made on individual grains in polycrystalline specimens of commercial grain-oriented 3% silicon-iron material. The loss-per-cycle against frequency characteristic of a grain is found to consist of discrete linear portions, which correspond to different domain-wall spacings. These changes

Analysis of iron losses in induction motor with an improved iron-loss model

2014 IEEE Conference and Expo Transportation Electrification Asia-Pacific (ITEC Asia-Pacific), 2014
In order to study iron loss distribution characteristics in stator and motor of induction motor, an improved iron-loss model with higher accuracy is proposed based on time-stepping finite elements. In Section Two,various iron loss formulaes are compared. followed by an miproved iron-loss model.

Verification of Iron Loss Calculation Method using a High-Precision Iron Loss Analyzer

IEEJ Transactions on Industry Applications, 2013
SUMMARYBecause of the improved performance of power devices, the volume of the ac filter inductors used in high‐frequency PWM inverters has been reduced. However, the temperature rise in the filter inductor due to this miniaturization has become more pronounced.

Measurements of Iron Loss in PMSM Stator Cores Based on CoFe and SiFe Lamination Sheets and Stemmed From Different Manufacturing Processes

IEEE transactions on magnetics, 2019
This paper deals with the experimental study of the iron losses under real operating conditions of a permanent magnet synchronous machine. The latter is a high frequency (>1 kHz) and high power-to-weight ratio (4 kW/kg) motor intended for an aerospace ...

Iron loss in machines with powdered iron stators

IEEE International Electric Machines and Drives Conference. IEMDC'99. Proceedings (Cat. No.99EX272), 2003
This paper describes iron loss measurements in a permanent magnet servomotor, which has a stator constructed with soft magnetic composites (SMCs). It is shown that whilst the SMC has significantly greater iron loss density than silicon iron steel, it has many other advantages. The SMC machine is shown to outperform its conventional laminated equivalent.
