<p>The present invention relates to a hand held gun-shaped air compressor device powered by, an electromagnetic' attraction and repulsion force. The device includes a ferrite core electromagnet acting as stator and a powerful N40 neodymium magnet acting as reciprocator along with a 12v battery, a 220V car inverter and an SCR triggered DC voltage doubler circuit to magnetize and demagnetize the electromagnet. Continuous attraction and repulsion process take place when the gun is triggered that causes suction and compression of air. The air compressor device can be used as a tyre inflator in automobiles and in various pneumatic applications.</p> |
