目的-最近，电动汽车或混合动力汽车的新概念电机的开发引起了相当大的关注。牵引电动机要求有较宽的转矩、转速可控范围和较高的传动效率。本文的目的是实现新概念的可变磁场磁通电机的爪极转子和无刷鲁棒结构的高速范围。设计/方法/途径-在以前的文件中，作者提出了一个半波整流无刷可变磁场磁通的方法与二极管插入到磁场绕组。提出了一种基于变磁场磁通法的新型爪极转子电机的设计方法。爪极型转子结构简单、坚固，适合高速运转。本文介绍了第一个原型设计结果CP-HVFM使用三维有限元。和作者报告的扭矩和效率特性的结果，使用3D-FEM。结果-作者研究了使用3D-FEM的CP-HVFM的设计。设计的原型CP-HVFM在实验设备和初始规格的设计限制下，在额定转速1,800 rpm时达到2kW或更高的额定功率。此外，作者发现的爪极形状的尖端和根部拥抱的比率，最大的平均转矩和最小的转矩涟漪。最后，作者揭示了电枢电流的转矩和效率特性的结果，为设计的原型CP-HVFM使用3D-FEM的影响。独创性/值-半波整流无刷可变磁场磁通的方法被证明是有效的爪极转子型电机。并找出了转矩特性最佳的爪极形状。这一结果适用于另一个概念电动汽车或混合动力汽车。
Purpose– Recently, considerable attention has been attracted to the development of the new concept motor for EV or HEV. Wider torque and speed controllable operating range and high efficiency under driving area are needed for traction motor. The purpose of this paper is to realize the new concept variable field flux motor with claw pole rotor and brushless robust structure for high-speed range.Design/methodology/approach– In the previous paper, the authors proposed a half-wave rectified brushless variable field flux method with a diode inserted into the field winding. This paper presents a designing for a novel claw pole rotor type motor using the variable field flux method (CP-HVFM). The claw pole type rotor has simple and robust structure for high-speed operation. This paper describes a first prototype design result for CP-HVFM using 3D-FEM. And the authors report the torque and efficiency characteristic results using 3D-FEM.Findings– The authors have studied the designing for CP-HVFM using 3D-FEM. The designed prototype CP-HVFM reached a rated power of 2 kW or more at a rated speed 1,800 rpm under design restrictions of experimental equipment and initial specifications. In addition, the authors found the ratio of the tip and root embrace of the claw pole shape for maximum average torque and minimum torque ripple. Finally, the authors revealed an influence of the armature current on the torque and the efficiency characteristic results for the designed prototype CP-HVFM using 3D-FEM.Originality/value– The half-wave rectified brushless variable field flux method proved to be effective for the claw pole rotor type motor. And also the authors found the best claw pole shape for torque characteristic. This results are applied to another concept motor for EV or HEV.
