A Novel Inline High-Efficiency Motor/Pump System

世界上约19%的电能和澳大利亚30%的电能都是由水泵技术消耗的。如果泵系统的主要组件，包括逆变器、电机和泵，在不同的负载下以其可能的最大效率运行，则可以显著节省能源。该项目中的一种新颖的泵设计在潜水式外壳中容纳了集成电子设备。无密封设计有助于缓解泵故障的几个方面，其直插式结构降低了组装成本。准确测量的效率图将被用来展示电机和泵数量之间的非线性关系，以及开发间接估计反馈量和实现最高系统效率的模型。

Around 19% of the world’s and 30% of the Australia’s electric energy is consumed by pump technologies. Significant energy savings are possible if the major components of pump systems, including inverter, motor and pump, operate at their maximum possible efficiency under varying loads. A novel pump design in this project accommodates integrated electronics in a submersible housing. A seal-less design helps mitigate several aspects of pump failure and its in-line structure reduces assembly cost. Accurately measured efficiency maps will be utilised to demonstrate the non-linear relationship between motor and pump quantities as well as developing models for indirectly estimating feedback quantities and achieving the highest system efficiency.
