Second Prototype

After the first bench test, we came to the realization that the output voltage produced by the generator was not sufficient. So we decided to make improvements to the design in the hopes of increasing its output. The second prototype was an adaptation of the first design. The physical construction remains unchanged from the first one, the only key change being the copper winding which  was increased to 600 windings (N), up from 300 N. The same test procedures were carried out to simulate the voltage output. The output waves of the second tests were captured in the following charts.

Figure - 1: Peak Voltage=2.168 V @ 1Hz

The results of the second prototype show that at a frequency of ±1Hz, the peak voltage has risen from 0.961V to 2.168V, while at a frequency of ±1.5Hz the peak voltage raised from 1.169V to 3.129V. With this in mind, the  generated current at these voltages was able to charge the 3900μF capacitor (accumulator) up to 0.961V.

The test results prove that the number of coil windings plays a substantial role in increasing the peak voltages at various frequencies, and also increasing the charging capacity through the higher amperage produced.
