Many machines require reciprocating motion and achieve it by mechanical conversion of rotary motion. In particular, pistons for liquid pumping and gas compression are usually driven by a crank on a rotary electric motor. Driving the piston directly by a linear motor eliminates the cost, weight, inefficiency and wear of the mechanical conversion. This project will design, construct and test high efficiency, tubular, linear permanent magnet motors for fluid pumping. Further, an intelligent electronic controller will be developed to control the motor speed and reversals without sensors in the motor. Initial applications will be solar powered water pumping and purification.

许多机器需要往复运动，并通过旋转运动的机械转换来实现。特别是，用于液体泵送和气体压缩的活塞通常由旋转电动机上的曲柄驱动。直线电机直接驱动活塞，消除了机械转换的成本、重量、效率低下和磨损。本项目将设计、建造和测试用于流体泵送的高效管状直线永磁电机。此外，将开发一种智能电子控制器来控制电机的速度和反转，而不需要在电机中安装传感器。最初的应用将是太阳能抽水和净化。
