Design of a permanent magnet linear generator

This paper present our experience in the design of a permanent magnet generator. The generator has a long translator and a permanent magnet mover as magnetic field source. It generates a three phase electrical current. The generator is proposed to be operated using a dual chamber free piston internal combustion linear engine. The finished product is to be placed in a hybrid electric vehicle to generate electricity to run the motors and to charge the batteries 111,[2]. The machine design is performed using a 2D finite element analysis. The generator produces a three phase voltage and the power output is 7 M This paper also presents the fabrication of the prototype.
