PROBLEM TO BE SOLVED: To provide a compact and high-power motor which is small, especially in an axial direction, and capable of attaining stable performance and easy layout. SOLUTION: This motor includes a first drive which consists of magnets, at least, which is formed with a gear at its outer periphery, divided in the circumference direction of the gear, and polarized to the different poles alternately, and which is rotatable around a rotating shaft, a coil in the axial direction of the magnet, and a stator in which an outer magnetic pole and an inner magnetic pole excited by the coil face the outer periphery and the inner periphery of the magnet, and a second drive unit which consists of a magnet, at least, whose outer periphery has a gear, is divided in the circumference direction of the gear, and polarized to the different poles alternately, and which is rotatable around a rotating shaft, a coil in the axial direction of the magnet, and a stator in which an outer magnetic pole and an inner magnetic pole excited by the coil face the outer periphery and the inner periphery of the magnet. The first and second drives are disposed so that their axial directions may be parallel with each other, and an output means is provided which has a gear engaged with the gear of the magnet of the first drive and the gear of the magnet of the second drive.
