PROBLEM TO BE SOLVED: To improve efficiency by current density, in a double armature motor excellent in downsizing and high efficiency.

SOLUTION: This motor is the so-called double armature motor which is equipped with a rotor 100, an inner stator 200 where an armature coil 201 is wound, and an outer stator 300 where an armature coil 301 is wound. The ratio of the sectional area of the armature coil 201 to the sectional area ϕ g of the armature coil 301 is selected to be equal to the ratio of the current Ig flowing to the armature coil 301 to the current In flowing to the armature coil 201.
