PROBLEM TO BE SOLVED: To eliminate cogging torque and impulse torque of a combined torque outputted from the common output shaft, by disposing in multiple stages, a plurality of axial gap motor portions. SOLUTION: An axial gap motor portion 2A comprises a stator 3 including Z coils 6, each of which is provided with a coil 7, and a rotor 11 in which a plurality pairs of permanent magnets 12 are disposed in the circumferential direction shape of magnet force. In this case, n (n is integer 2 or larger) motor portions 2A, 2B, and so on are disposed in a line in the axial direction and are accommodated in only one housing 10 with the respective output shafts 14 connected in common. With the position of the stator 3A of a certain first motor portion 2A being determined as the reference position, the mounting positions of the stators 3B, 3C,..., 3n of the second, third,..., n-th motor portions 2B, 2C,..., 2n are respectively determined with displacement by the formulaθn=(360 deg.÷Z÷n)×(n-1) (where,θn indicates the mounting position of the n-th stator).
