This paper presents a novel design for switched reluctance motors characterized by the reduction of torque ripple and windage loss. An asymmetric rotor skew structure is proposed to decrease the torque ripple and investigated by both 2D and 3D finite element analysis (FEA) simulations. Moreover, the prototype is constructed by additive manufacturing (namely 3D printing); thus, the performance of the...
The switched reluctance type integrated starter generator (SRISG) has the potential to be applied in hybrid electric vehicles for its robust structure, and it does not feature a magnet. In this paper, a new double-gap SRISG design that can provide higher power is presented. Characteristics, such as torque ripple, charging ability, and efficiency, are investigated by both 2D and 3D finite element analysis...
The synchronous reluctance motor (SynRM) is widely used because of its excellent performance such as high efficiency and accurate speed control. In this paper, the rotor with the squirrel cage consisted of three design parts is shown. An additive manufacturing method (selective laser melting) for fabricating the three parts of the rotor in one build is shown. A complex SynRM based on selective laser...
Synchronous reluctance motors (SynRM) have been widely used because of their excellent performance, such as high efficiency and accurate speed control. This paper focused on the efficiency and starting ability of SynRM. Based on the view of steel sheet material and motor fabrication, the iron loss influences on SynRM regarding different grades of silicon steel are compared, and the performance of...
This paper presents a novel double salient motor design in which the permanent magnets are implanted in the stator to provide additional magnetic flux sources for enhancing its performance and reducing the inherent cogging torque. The feasible cones method is adopted to calculate the dimensional sizes of the proposed short flux path motor. The assembled stators concept is employed to design the magnetic...
Recently, the motor eccentricity problem, which can cause vibrations and noise, has become increasingly important due to the growing demand for improved quality of life and work environment. Because the eccentricity problem causes an imbalance of electromagnetic forces, most of the previous research has focused on the analysis of this concern. However, motor eccentricity can also influence the operating...
