In rail transit traction, due to the remarkable energy-saving and low-cost characteristics, synchronous reluctance motors (SynRM) may be a potential substitute for traditional AC motors. However, in the parameter extraction of SynRM nonlinear magnetic model, the accuracy and robustness of the metaheuristic algorithm is restricted by the excessive dependence on fitness evaluation. In this paper, a novel probability-driven smart collaborative performance (SCP) is defined to quantify the comprehensive contribution of candidate solution in current population. With the quantitative results of SCP as feedback in-formation, an algorithm updating mechanism with improved evolutionary quality is established. The allocation of computing resources induced by SCP achieves a good balance between exploration and exploitation. Comprehensive experiment results demonstrate better effectiveness of SCP-induced algorithms to the proposed synchronous reluctance machine magnetic model. Accuracy and robustness of the proposed algorithms are ranked first in the comparison result statistics with other well-known algorithms.

Die Energieeffizienz von modernen Motorspindelsystemen wirkt sich direkt auf deren thermisches Verhalten aus. 60 % der in Werkzeugmaschinen verbauten Motorspindeln basieren auf asynchroner Technologie. Neben ihrem robusten, kostengünstigen und einfachen Aufbau bringen sie auch einige Nachteile mit sich. Diese sind vor allem in ihrem thermischen Verhalten begründet. Durch die starke Rotorerwärmung müssen aufwendige Lagerungen vorgesehen werden. Dieser Problematik kann mit dem Einsatz eines alternativen Antriebstyps in Motorspindeln – dem Synchronreluktanzantrieb – begegnet werden. Durch die systembedingt geringen thermischen Verluste lassen sich einfachere Lagerungsstrategien aufbauen.   The energy efficiency of modern motor spindle systems has a direct impact on their thermal behavior. 60 % of the installed motor spindles are based on asynchronous drives. In addition to its robust, low cost and simple construction, they also have some disadvantages. These are mainly caused by their thermal behavior. Due to the strong rotor heating an elaborate bearing concept has to be build. This problem can be addressed through the use of a new class of motor spindles drive, the synchronous reluctance machine. Due to the low-loss operating behavior more simple bearing concepts can be applicated.

Purpose The purpose of this paper is to propose a permanent magnet-assisted synchronous reluctance machine (PMASynRM) using ferrite magnets with the same power density as rare-earth PM synchronous motors used in Toyota Prius 2010. Design/methodology/approach A novel rotor structure with rectangular PMs is discussed with respect to the demagnetization of ferrite magnets and mechanical strength. Some electromagnetic characteristics including torque, output power, loss and efficiency are calculated by 2D finite element analysis. Findings The results of the analysis show that a high power density and high efficiency for PMASynRM can be achieved using ferrite magnets. Originality/value This paper proposes a novel rotor structure of PMASynRM with low-cost ferrite magnets that achieves high power density as permanent machines with rare-earth PMs.
