Development of a miniature air compressor driven with a linear electromagnetic actuator

This paper deals with a new type of miniature air compressor that it mainly consists of a linear electromagnetic actuator, electronic drive circuit, rubber cylinders intake and exhaust valves. The characteristics of the developed compressor are experimentally investigated. Only driven with the resonant frequency the compressor can offer good performances were proven. Furthermore, by means of modulating the duty ratio of the driving signal, charging pressure control is possibly carried out and its possibility was tested by experiment results.
