Abstract
A motor includes a rotor fixed to a rotary shaft, a stator arranged so as to surround the rotor with a gap from the rotor in a radial direction orthogonal to an axis direction of the rotary shaft, and a case accommodating the rotor and the stator. The rotor includes a plurality of rotor cores made from a soft magnetic material, and a rotor fixing member that fixes the rotor cores. The stator includes a plurality of stator cores made from a soft magnetic material, a stator fixing member that fixes the stator cores, and coils wound around the stator cores, respectively. The motor includes at least two sets of the rotor and the stator, and the sets are stacked in an axis direction of the rotary shaft.
