PM material selection guide for IPMSM
2016 XXII International Conference on Electrical Machines (ICEM), 2016The aim of this paper is to provide a well-organized design procedure for selecting the proper permanent magnet (PM) material to be used in constructing the interior permanent magnet synchronous machines (IPMSM). A simple and clear design flow chart is introduced to support the machine designer in each design step. The design starts by selecting one of

The shape design of IPMSM for the efficiency improvement
2014 17th International Conference on Electrical Machines and Systems (ICEMS), 2014The operating characteristics was calculated through a finite element analysis (Maxwell). Iron loss and copper loss was estimated through the calculation and the mechanical loss is the result of the experiment for the calculation of the efficiency. In this paper, the shape design of IPMSM(Interior Permanent Magnet Synchronous Motor) for improving the ...

Current Sensorless MTPA for IPMSM Drives
IEEE/ASME Transactions on Mechatronics, 2017In this paper, a maximum torque per ampere (MTPA) control strategy is presented for interior permanent magnet synchronous machines (IPMSMs) without current sensing or regulation. The developed control scheme achieves MTPA using a direct voltage control method, which varies the machine's stator voltage amplitude and angle.

A reduction method of cogging torque for IPMSM
2005 International Conference on Electrical Machines and Systems, 2005This paper describes a reduction technique of the cogging torque in an interior permanent magnet synchronous motor (IPMSM). IPMSM usually has the flux barrier for preventing the short circuit of magnetic flux near the magnet. The flux barrier can reduce the cogging torque, and therefore the shape of the flux barrier of IPMSM with concentrated winding ...

An Improved Rotor Cooling Structure of IPMSM
2019 22nd International Conference on Electrical Machines and Systems (ICEMS), 2019For the interior permanent magnet synchronous machine, the rotor temperature at the axial center is high because of its low axial thermal conductivity. The conventional the rotor structure with axial and radial vent holes has low air velocity in the axial center position, so the cooling performance for the rotor is unsatisfactory.

Detection and Classification of Demagnetization and Interturn Short Faults of IPMSMs
IEEE Transactions on Industrial Electronics, 2017Wepresent a method that detects and classifies demagnetization and interturn short faults (ISFs), which degrade the performance of permanent-magnet synchronous machines (PMSMs). Demagnetization and ISF are analyzed using models; we focused on changes of magnitude and angle of currents in the synchronous frame. Those two faults increase the magnitude of

Impact of heat treatment on core properties and IPMSM performance
IECON 2012 - 38th Annual Conference on IEEE Industrial Electronics Society, 2012This paper presents the predicted performance of an interior permanent magnet synchronous machine (IPMSM) operating in wide speed range. The predictions are carried out with material properties obtained using from Epstein tests on samples that have undergone different treatments together with stress released annealing.

“Active Flux” DTFC-SVM Sensorless Control of IPMSM
IEEE Transactions on Energy Conversion, 2009This paper proposes an implementation of a motionsensorless control system in wide speed range based on "active flux" observer, and direct torque and flux control with space vector modulation (DTFC-SVM) for the interior permanent magnet synchronous motor (IPMSM), without signal injection.
