This paper presents the design and modeling of a portable pico linear permanent magnet generator for the application of wave energy conversion system. Two types of generator technology namely the rotary and linear are identified but due to the high maintenance and low efficiency of rotary, linear generator is preferable. Three linear permanent magnet generator designs with different types of permanent magnet shape have been proposed. Preliminary results for the air gap distribution and open circuit test are demonstrated and discussed are shown to be as expected. © 2013 IEEE.
