Design and development of a novel test cell for low-voltage, high-speed interior permanent magnet synchronous machines

传统的基于内燃机（ICE）的车辆遭受高排放和高燃料消耗，特别是在频繁的起动-停止循环中的冷起动和加速期间。集成的起动发电机（伊萨）保持了ICE车辆中传统起动机和发电机的功能，并为停止的发动机提供平稳的起动。在这个拟议的项目中，将与我们的行业合作伙伴D&V Electronics一起设计和开发一个独特的测试单元，以测试和评估用于皮带驱动伊萨应用的低压，高速内置永磁同步电机（IPMSM）。考虑到使用低压电池的可用电压以及发动机和伊萨之间的皮带转换率，测试中的IPMSM将在高达60 V的端电压下运行，并在高达20，000 rpm的扩展速度范围内发电。

Conventional internal combustion engine (ICE) based vehicles suffer from high emissions and high fuel consumption, especially during cold cranking and acceleration in frequent start-stop cycles. The integrated starter alternator (ISA) maintains the functions of the conventional starter and generator in an ICE vehicle, and provides a smooth start to the stopped engine. In this proposed project, a unique test cell will be designed and developed with our industry partner, D&V Electronics, to test and evaluate low-voltage, high-speed interior permanent magnet synchronous machines (IPMSM) for belt driven ISA applications. Considering the available voltage with the use of low-voltage batteries and the conversion ratio of the belt between the engine and ISA, the IPMSM under test will operate with a terminal voltage of up to 60V and generate within an extended speed range of up to 20,000 rpm.
