Minimization of Iron Losses of Permanent Magnet Synchronous Machines

IEEE Transactions on Energy Conversion, 2002
In permanent magnet (PM) synchronous machines, iron losses form a larger portion of the total losses than in induction machines. This is partly due to the elimination of significant rotor loss in PM machines and partly due to the nonsinusoidal flux density waveforms in the stator core of PM machines.

Control of permanent magnet synchronous machines for subsea applications

2017 Petroleum and Chemical Industry Technical Conference (PCIC), 2017
Medium voltage permanent magnet synchronous motor (PMSM) driven subsea pumps have the potential to improve system efficiency and reliability to lower the operating costs, and reduce the subsea pump module (PM) weight and size. These subsea pumps can be deployed in the well, in a dummy well or on the mudline in a skidded configuration. The higher speeds

Study on the Permanent Magnet Demagnetization Fault in Permanent Magnet Synchronous Machines

IECON 2006 - 32nd Annual Conference on IEEE Industrial Electronics, 2006
This article studies the permanent magnet demagnetization fault in permanent magnet synchronous machines (PMSM). The study is carried out by analyzing the harmonics obtained using the fast Fourier transform (FFT) of stator and zero sequence currents at nominal torque for the whole range of machine operation speeds.

Machine Learning to optimize Permanent Magnet Synchronous Machines

2020 IEEE 2nd International Conference on Civil Aviation Safety and Information Technology (ICCASIT, 2020
In this paper, we offer a possible approach to estimating motor parameters: Machine Learning. We begin with a simulation of a Permanent Magnet Synchronous Motor (PMSM) model using MATLAB and Simulink. We measure the voltage and current and then send the data to a machine learning model (TensorFlow).

Study on Permanent Magnet Demagnetization Characteristics in Permanent Magnet Synchronous Machines

Advanced Materials Research, 2011
When Permanent Magnet Synchronous Machines (PMSM) working with rated load or overload, stator iron loss and copper loss, bearings friction loss, permanent magnet (PM) eddy-current all will cause PM temperature rise. In this condition, the PM is affected by the temperature and the stator of the reverse magnetic field generated prone to arouse ...

Dynamic Permanent Magnet Flux Estimation of Permanent Magnet Synchronous Machines

IEEE Transactions on Applied Superconductivity, 2010
This paper deals with rotor flux estimation in permanent magnet synchronous motor(PMSM). In most application, the rotor flux linkage is treated as a known constant. However a high operation temperature or a stator winding current impulse may cause magnet flux ripple or demagnetization which has direct impact on machines performance.
