Optimization of Current Excitation for Permanent Magnet Linear Synchronous Motors
The main problem in improving the tracking performance of permanent magnet linear synchronous motors is the presence of force ripple caused by mismatched current excitation. This paper presents a method to optimize the current excitation of the motors in order to generate smooth force. The optimized phase current waveforms produce minimal ohmic losses and maximize motor efficiency. The current ...
متن کاملPermanent Magnet Linear Generator Design
The purpose of this design is to improve the efficiency of power extraction from sea waves. Sea waves are huge untapped energy resources. There are many methods to generate electricity from power of sea waves. But, all these conventional methods use mechanics, which have a lesser efficiency than electrical systems. A new design of permanent magnet linear generator is proposed which moves with t...
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 ...
متن کاملModeling 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...
