전기자동차의 구동시스템은 주행속도 확보(고속영역 동작)와 등판 및 가속능력 확보(고 토크영역 동작)를 위해 넓은 운전영역을 필요로 한다. 일반적으로 토크영역을 확보하는 설계를 하고 약계자 제어로 고속영역 동작을 가능하게 하거나, 기계식 변속기를 사용한다. 하지만, 전자의 경우 고속에서 효율저하가 발생하며 정확한 전류 위상 제어의 어려움이 따르고, 후자의 경우 기계적인 변속 충격이 문제가 된다. 본 논문에서는, 이러한 문제점을 극복하고 전기자동차 구동시스템의 성능확보를 위한 전자식 변속시스템을 제안한다. 본 논문에서 언급하는 전자식 변속시스템은 구동모터의 권선을 직, 병렬화 하여 구현이 가능하며, 고토크 및 고효율의 고속운전을 가능하게 한다. 또한 변속시 발생되는 충격을 최소화하는 하드웨어 토폴로지 및 제어 알고리즘을 제안하고 해석을 통해 타당성을 증명하였다.

This paper deals that the optimal design of integrated starter and generator(ISG) which is one of the most important parts of hybrid electric vehicle. The interior type permanent magnet synchronous reluctance motor which energy density is relatively higher than other types of motors is employed to optimal design. The optimal design is performed using design of experiment related with response surface methodology. Two wining types, distributed and concentrated type, is considered to optimal design. ISG is operated not only motor in low speed region but also generator main driving region of the vehicle. Therefore the object function of optimal design is decided that output torque and improving the total harmonic distortion to maximize generating efficiency. The d, q axis equivalent circuit analysis is performed to calculate characteristics such as torque, power, line current and efficiency according to operating speed.

This paper deals with the weight reduction design of In-Wheel type motor. Therefore, characteristic and weight of motor according to change in reduction gear ratio are examined. The weight of construction and reduction gear following the increase of gear ratio are also considered. Weight of motor is minimized by modulating the ratio of stack length and external diameter of stator. Then, In-Wheel motor geometry based on the prototype motor is optimized to get the determined parameters using response surface methodology (RSM) and Finite Element Method (FEM). Optimal design of core usage in rotor is conducted for minimizing weight of motor which has identical characteristic to prototype motor. Characteristic analysis is conducted by using equivalent circuit analysis of PM type motor. Through the presented weight of In-Wheel type motor, total weight is reduced to 25% of prototype motor.

When the in-wheel motor is applied to the vehicle, the differential gear and the drive shaft are removed, thereby increasing the spatial design freedom in the vehicle layout, and can also be used to control vehicle motion through independent torque control of the in-wheel motor. The point of design of the in-wheel motor is the harmonious and concise packaging of the surrounding components, such as suspension, brake, hub, and reduction gear, in a given space within the wheel. In particular, the inherent performance of the surrounding components shall not be reduced due to the mounting of the in-wheel motor. This study is about the design of the in-wheel motor for the rear wheels of a ultra-small electric truck, and the design of the in-wheel motor for vehicles with disc brake and torsion beam axle suspension. where the in-wheel motor was designed based on the excellent buried permanent magnetic motor motor in efficiency and size, and the reduction gear was applied with the planetary gear. In the primary design and manufacture of the motor, a motor with a small outer diameter and a long length in the axial direction of the motor was designed, but in the secondary design, the motor was able to increase the outer diameter of the motor and shorten the axial length of the motor by improving the packaging design with the brake caliper and packaging the reduction gear into the rotor of the motor.
