1. An air compressor comprising:
a housing;
a rotating shaft extending in a longitudinal direction in the housing;
a compression unit which is disposed at a front side of the rotating shaft and rotated by the rotating shaft to compress and discharge introduced air;
a motor unit which rotates the rotating shaft;
a control board which controls the motor unit;
a filter unit which supplies external power to the control board and filters noise of the power; and
a busbar assembly which transmits power of the control board to the motor unit,
wherein the filter unit includes:
a transistor connected to the control board;
a capacitor assembly connected to one side of the transistor; and
a current sensor assembly connected to the other side of the transistor,
wherein the capacitor assembly and the current sensor assembly are disposed at opposite sides with respect to the busbar assembly;
wherein the busbar assembly includes:
a plurality of busbars electrically connected to the motor unit; and
a busbar fixing member which fixes the plurality of busbars to the housing in a state in which the plurality of busbars are insulated,
wherein the plurality of busbars extend outward from the motor unit in the radial direction,
wherein each of the plurality of busbars has an end, and
each respective end of the plurality of busbars is bent in different directions,
wherein each respective end of the plurality of busbars are is exposed from the busbar fixing member in a state in which the end respective ends of the plurality of busbars are spaced apart from each other.
