To extremely improve high power density of a disc type permanent magnet synchronous motor (PMSM), the results are simulated with finite element method considering the electro-magnetic, fluid and thermal. Motor output power and temperature rise with different water are calculated by flow analysis. The rationality of thermal conductivities of materials are proved by comparing the calculated results with the test data, which could be referred in the design of this kind of motor.

4.An improved analytical method for eddy-current losses and thermal analysis in permanent magnets of PMSMs
http://www.yanfabu.com/wk_index_fileview_id_33272.html
This paper researches the principles of eddy-current losses of permanent magnet synchronous motor. Firstly, the paper establishes an analytical model of the flux density in magnets and eddy-current density from the point of views of eddy field and harmonic model. At the same time, the comparison of FEA and analytical result are put forward. In order to analyze the influence of eddy-current losses to the stability of high power-density and different magnet structure to the temperature rise of PMSMs, the paper provides the thermal
analysis of prototype motor. It is shown that the analysis results can provide directive value for motor design and stability analysis.

5.A low-order thermal model for monitoring critical temperatures in permanent magnet synchronous motors
http://www.yanfabu.com/wk_index_fileview_id_33273.html
Monitoring critical temperatures in electric motors is crucial for preventing shortened motor life spans due to excessive thermal stress. With regard to permanent magnet synchronous motors (PMSM), critical temperatures can occur in the magnets and the stator end winding. While excessive magnet

http://www.yanfabu.com/wk_index_fileview_id_33274.html
In this paper thermal behavior of a 600kW 4200r/min interior permanent magnet synchronous motor (PMSM) with forced ventilation in the stator was analyzed using Fluent. Due to its high power density and compact structure, accurate thermal analysis of PMSM traction machine is of great importance in designing and optimizing. Different structures of stator ventilation are evaluated and the square ventilation structure in the inner surface of house is selected.

7.Thermal evaluation of different drive train topologies for electrichybrid vehicles
http://www.yanfabu.com/wk_index_fileview_id_33275.html
The aim of this paper is to study the influence of the drive train topology on the temperature of the different components in permanent magnet synchronous motor (PMSM) drives applied to electric/hybrid vehicles. The temperature is a critical parameter because it is directly related to the lifetime and reliability of a device. This is particular important for PMSMs since it also influences the magnetic flux produced by the permanent magnets.

8.Rotor surface ferrite magnet synchronous machine for generator use in a hybrid application — Electro-magnetic and thermal analysis
http://www.yanfabu.com/wk_index_fileview_id_33276.html
To reach a particular tangential stress in a PMSM the magnetic loading and the electric loading should have corresponding values. This means that if the magnetic loading is restricted by the characteristics of cheap and relatively weak ferrite permanent magnets, the electric loading should be increased to keep the tangential stress at desirable value. However, the latter is also limited because of the demagnetization risk of the permanent magnets by a high armature reaction.

9.Analysis of losses and thermal model in a surface-mounted permanent-magnet synchronous machine over a wide- voltage range of rated output power operation
http://www.yanfabu.com/wk_index_fileview_id_33277.html
This paper shows the results of permanent magnet eddy current loss, iron core loss and Copper loss of a surface permanent magnet synchronous machine. A thermal model for the temperature of all motor components is also presented in the paper. This PMSM will be operated at the voltage 700-1000V powered by the battery pack. So the losses are calculated separately at four different DC link voltages (700V, 800V, 900V, 1000V). The analysis shows that this motor should stop working to avoid damage at very low voltage.
