Ante-projeto de uma máquina elétrica linear a imãs permanentes.

Abstract

This work presents a way to simulate the behavior of magnetic field along a permanent magnet linear electric machine. The use of permanent magnets is an alternative to electric machines’ designs. They replace the field windings of conventional machines in applications that require high performance. Most of designs of electric machines with permanent magnets considers a primary mechanical movement like rotary type. In this work is discussed a new form of primary actuator, which uses a linear motion. In the sphere of linear primary machines, the most used are the free - piston engines or Stirling engines. Among the topologies found in the literature, the short stroke generator gained prominence. The phases of the project will consider comparative studies and simulations. The simulation results show the behavior of the magnetic flux along the structure, as well as their distribution depending on the position of the movel part of the machine.
