Abstract:
An apparatus for controlling an air compressor, comprising:a controller for controlling an operation of said apparatus; an inverter circuit interfaced between the controller and the air compressor and used for modulating a frequency of a drive signal for the air compressor in response to a control signal output from the controller, and outputting the modulated drive signal to the air compressor so as to control the operation of said air compressor and to control the rpm of the air compressor; a temperature sensor connected to said controller and used for sensing a temperature of lubrication oil of the compressor and outputting a temperature signal to the controller; a main air tank connected to the air compressor through an air pipeline and used for storing compressed air supplied from the air compressor; and a pressure sensor connected to the controller and used for sensing a pressure of compressed air stored within the air tank and outputting a pressure signal to the controller.
