Permanent Magnet Synchronous Machines With Nonuniformly Distributed Teeth
IEEE Transactions on Industrial Electronics, 2022An increasing interest for permanent magnet synchronous machines with low torque ripple and low vibration is observed. The purpose of this paper is to investigate the topology of non-uniformly distributed teeth and its influence of on cogging torque, tooth ripple harmonics and torque ripple of permanent magnet synchronous machines.

Demagnetization characteristics of permanent magnet synchronous machines
IECON 2014 - 40th Annual Conference of the IEEE Industrial Electronics Society, 2014This paper presents the calculated demagnetization characteristics of different types of permanent magnet synchronous machines (PMSMs) under the influence of demagnetizing MMF contributed by the stator currents (i.e., armature reaction). The demagnetization of NdFeB magnets is quantified in terms of demagnetized magnet volume and loss of magnet ...

Dynamic simulation of permanent magnet synchronous machine
Proceedings of the 12th IEEE Mediterranean Electrotechnical Conference (IEEE Cat. No.04CH37521), 2004Electric drive is increasingly gaining in importance within the general ship propulsion system. Contemporary electric propulsion mainly contains a fixed propeller, a synchronous or asynchronous propulsion engine and PWM frequency converter with an adequate drive.

Electric Machine Design Tool for Permanent Magnet Synchronous Machines
2019 Fourteenth International Conference on Ecological Vehicles and Renewable Energies (EVER), 2019Since various machine parameters of existing electric machines are subject to confidentiality agreements of manufacturers, machine data sheets are often incomplete, making an accurate simulation and validation of machine design tools difficult but inevitable.

Permanent magnets synchronous machines faults detection and identification
IECON 2012 - 38th Annual Conference on IEEE Industrial Electronics Society, 2012The reported work is the design of a Fault Detection system for permanent magnet synchronous machines (PMSM). Two main faults occurring on these machines are identified as inter-turns short-circuits and rotor single pole demagnetization, and characterized. An analytical model of the PMSM is developed and simulated using Matlab Simulink.

Simple Size Determination of Permanent-Magnet Synchronous Machines
IEEE Transactions on Industrial Electronics, 2017Today, performance improvements such as reducing the time response and enhancing the efficiency of the electrical motor are one of the most important challenges. In the design of a permanent-magnet (PM) motor, the variables for sizing include the shape ratio (SR), the torque per rotor volume (TRV), and the torque density (TD), and these variables are ...

Control of permanent magnet synchronous machines for subsea applications
2017 Petroleum and Chemical Industry Technical Conference (PCIC), 2017Medium 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
