Modeling of Eddy Current Loss and temperature of the magnets in Permanent magnet Machines
The eddy current loss in the magnets of permanent magnet (PM) motors in a hybrid electric vehicle (HEV) and plug-in HEV is usually not taken into consideration in traditional motor design and analysis. However, due to the high conductivity of the rare-earth magnet, neodymium-iron-boron (NdFeB), and slot/tooth harmonics, there is eddy current loss generated inside the magnets. This loss may not ...
متن کاملValidation of Eddy Current Loss Models for Permanent Magnet Machines with Concentrated Windings
Acknowledgement Thanks to my parents. Without your spiritual and financial supports, I could not have got the chance to study in the Netherlands and finish my master programme at TU Delft. I feel very sorry that you must have been feeling alone without the only child at home. Thank you all the time for your understanding. Thanks to my supervisor Dr. Henk Polinder. You have given me great help a...
متن کاملModeling and analysis of eddy current losses in permanent magnet machines with multi-stranded bundle conductors
This paper investigates the influence of eddy current losses in multi-stranded bundle conductors employed in outrunner permanent magnet machines, by adopting an analytical model. The analytical model is based on a sub-domain field model that solves the two-dimensional magnetostatic problem using the separation of variables technique for each of the non-magnetically permeable machine sub-domains...
متن کاملVarying Magnetization Orientation for Permanent-Magnet Volume Reduction in Machines
We present an enhanced version of a method to minimize the amount of permanent-magnet (PM) material required to create a certain flux linkage in the stator winding of a PM machine. The enhanced version obtains the distribution of the factor inside the PM; identifies the areas inside the PM volume where the orientation of magnetization may be modified, so as to further increase the amount of no-...
متن کاملThe Design of Eddy-current Magnet Brakes
The eddy-current is created by the relative motion between a magnet and a metal (or alloy) conductor. The current induces the reverse magnetic field and results in the deceleration of motion. The proposed mechanism implements this phenomenon in developing a braking system. The potential applications of the braking system can be a decelerating system to increase the safety of an elevator or any ...
