1. A motor comprising:
a rotor rotatable about a center axis;
a stator including coils and radially opposing the rotor;
a drive source assembly including a first wiring electrically connected to the coils;
a rotation detector including a rotation sensor to detect rotation of the rotor and a second wiring electrically connected to the rotation sensor; and
a motor housing that accommodates the rotor, the stator, the drive source assembly, and the rotation detector therein; wherein
the motor housing includes:
a tubular first motor housing that is open to one axial side and accommodates at least a portion of the drive source assembly; and
a tubular second motor housing that opposes one axial side of the tubular first motor housing, is open to another axial side, and accommodates at least a portion of the rotation detector;
the tubular first motor housing includes a first penetration portion that radially penetrates a circumferential wall portion of the tubular first motor housing and is open to one axial side;
the tubular second motor housing includes a second penetration portion that radially penetrates a circumferential wall portion of the tubular second motor housing and is open to another axial side;
the first wiring is lead to an outside of the tubular first motor housing via the first penetration portion; and
the second wiring is lead to an outside of the tubular second motor housing via the second penetration portion.
