This paper presents the design and analysis of an interior permanent magnet synchronous motor (IPMSM) with a novel tangentially magnetized rotor for refrigerant compressors in inverter air-conditioners. To reduce cogging torque, torque ripple, and the weight of magnet usage, a new salient pole rotor design is proposed using permanent magnets arranged for tangential magnetization. The results of magnetic...
In this study, a novel, cost-effective consequent-pole interior permanent-magnet motor is designed to be applied in inverter-based air-conditioner refrigerant compressor. As the proposed motor has lesser magnetic usage, its performance variations based on four geometric parameters were studied. Moreover, a multi-target fuzzy-inference Taguchi method is employed to determine the best parameters combination...
In this paper, a novel flux-intensifying interior permanent-magnet motor (FI-IPM) with cost-effectiveness has been designed for applying to inverter-based air-conditioner refrigerant compressor. For satisfying both the load torque demand and the cost-effectiveness requirement, two kinds of tangentially magnetized PMs are employed by the proposed FI-IPM. One is the Dy-free MAGFINE to product main magnetic...
To improve the operation performances of an interior permanent-magnet synchronous motor (IPMSM) under field-weakening (FW) control mode, this paper presented a multi-objective optimization design method to obtain the optimal geometric parameters of IPMSM to achieve multiple quality targets for an inverter-based refrigerant compressor application. Three design targets that contain the high reluctance...
In this paper, a novel systematic and efficient approach, using the fuzzy-based Taguchi method with multiple performance characteristics index (MPCI), is employed for obtaining the robust design of an in-wheel permanent-magnet (PM) motor with both lower torque ripple factor and higher efficiency. According to the geometric parameters of the PM motor, we select the controllable factors and their levels,...
