Abstract :
The authors present the experimental procedure to build a high power handheld-sized Linear Permanent Magnet Synchronous Generator (LPM SG) powered by human motion. This generator produces maximum energy for charging small-scale electronic devices such as mobile phones. Two different generator prototypes are compared through the presented theoretical and experimental results based on parallel charging of two 5V Li-ion battery supplies. The systematic choice of rare earth material PM, magnetization direction, solenoid wire diameter and number of turns have increased the generated power by more than tenfold between the discussed prototypes.
