   Natural Frequencies of Small Squirrel Cage Induction Machine Rotor - Finite Element Model Optimization
By Jan SOBRA [View]
[Download]

Abstract: The paper deals with possibilities of geometry simplification for FE structural model calculating natural frequencies and mode shapes of rotor of small squirrel-cage induction motor. Proposed simplifications lead to the computing time savings while good result accuracy is preserved. All results are verified by experimental measurement.

   Numerical Iron Loss Computation Method for Switched Reluctance Motors
By Mario GREULE [View]
[Download]

Abstract: Iron losses are an important issue in high speed switched reluctance motors. A tool chain for the analysis of iron losses is introduced where arbitrary control schemes can be applied and a two-dimensional local loss distribution can be derived. The results are compared to a conventional calculation where individual machine components of uniform flux distribution in either tangential or radial direction are considered. Furthermore, the local influence of short and long flux path connection on the iron losses is analyzed.

   Pareto Optimization of Switched Reluctance Motors to determine the Optimum Pole Configuration
By Mario GREULE [View]
[Download]

Abstract: Switched reluctance motors are a promising low cost alternative for electric vehicles. The most promising stator pole / rotor pole configuration for high rotational speeds is often being discussed. In this work, Pareto sets of SRM designs are generated with respect to efficiency and maximum power density in order to provide a basis for the decision of the most promising pole configuration at different motor speeds.

   Torque analysis and comparison of the switched reluctance machine and the doubly-salient permanent magnet machine
By Jing OU [View]
[Download]

Abstract: Based on Schwarz-Christoffel mapping and Maxwell stress tensor, new analytical formulas to calculate the torque of the SRM and DSPMM are derived. Through the new expression, it is easy to understand the relationship between the torque and the design parameters of the machine. Additionally, the force distribution on the rotor tooth contour is presented. By using the torque formulas, the torque densities of the two machines are compared. Finally, the analytical formulas are verified by FEA method.
