1. An air compressor comprising:
a motor;
a compressor configured to be driven by the motor; and
a crankcase in which a part of the compressor is incorporated, wherein the motor includes:
a central shaft extending in an axial direction;
a stator extending in the axial direction around the central shaft;
a rotor facing in a radial direction an outer side of the stator and configured to rotate with the central shaft; and
a substrate which is located on one side of the rotor in the axial direction and on which a rotation position detection circuit configured to detect a rotation position of the rotor is mounted, the substrate is configured to be removed from the crankcase in a direction perpendicular to the axial direction,

the crankcase includes a fixing portion comprising an aperture formed in the crankcase and configured to fix the substrate,
the substrate includes a fixed portion fixed to the fixing portion, wherein the fixed portion of the substrate is fixed to a rotor side of the fixing portion of the crankcase, and
the fixing portion and the fixed portion are located on an outer side of the rotor in the radial direction.
