제안 방법
- However, the high speed operation will cause a fairly large centrifugal force on the rotor, and this force may cause mechanical problems [4-6]. In this study, these problems are addressed and a design approach explained that will help resolve the issue.
- The operating point of the permanent magnet was lowered when air gap length was increased, and torque was consequently reduced. The 1.2mm air gap model considering the torque margin as a tolerance and a stray-load loss was determined as the improved model.
- The characteristic analysis of the initial model and the shape design were performed, and the experiment was also performed after production. The design approach, which reduces the price of PMSM, was performed in the shape design by FEA.
- The produced motor sustained damaged due to the high centrifugal force during the high speed rotation experiment. To compensate for this, the improved model, which provides the desired torque and improves mechanical durability, was designed by an FEA of electromagnetic analysis and stress analysis. The FEA analysis results of the improved model were adequately verified through experiment.
대상 데이터
- The main application of an interior permanent magnet synchronous motor (IPMSM) is a traction motor for fuel cell electric vehicles, hybrid electric vehicles, and battery electric vehicles. The hybrid vehicle systems are divided into three parts: SHEV (series hybrid electric vehicle), PHEV (parallel hybrid electric vehicle) and PSHEV (power split hybrid electric vehicle). Among them, the SHEV should operate all driving areas of the vehicle by pure motor propulsion.
- This study introduced a 120kW class IPMSM for the traction motors of SHEV military trucks. In the basic design, a model having excellent electromagnetic performance except for mechanical durability was designed.
