Design of a 5 kW Tubular Permanent Magnet Linear Generator

摘要

A tubular permanent magnet linear generator with the output power of 5 kW and output voltage of 200 V with minimum cogging force is designed, simulated and fabricated. Specific design criteria are employed to meet exclusive requirements related to its stator and translator. A simple model of the electromagnetic analysis of the cogging force and generated emf is presented. Finite element software is used to simulate the machine. The linear machine is developed based on the results of finite element simulation. A radially magnetized magnet is chosen to give a high performance and to solve the cogging force-voltage problem.
