<p>A motor of an automatic winder includes a casing, stators, a rotor, a first bearing, and a second bearing. The stators are fixed to the casing. The rotor is arranged inside the stators. The first bearing and the second bearing are arranged facing each other to provide support to two ends of the rotor. An opposing face of the first bearing that faces the second bearing is positioned closer to the second bearing than a bobbin holder side end face of the stator. An opposing face of the second bearing that faces the first bearing is positioned closer to the first bearing than a sensor side end face of the stator.
