Abstract: Provided is a double-shaft motor. The double-shaft motor comprises a shell, a rotor shaft, at least three rotor core sets, and at least three stator cores, the rotor shaft extends in the axial direction and can perform translation along the axial direction relative to the shell and rotate along the circumferential direction, each rotor core set comprises at least a rotor core, the rotor cores are fixedly arranged on the rotor shaft in a sleeved manner and distributed at intervals along the axial direction, the rotor cores outwardly extend in a protruding manner to form a plurality of rotor teeth arranged at intervals along the circumferential direction, each stator core comprises at least two stator pole sets, each stator pole set comprises at least a stator pole, and each stator pole is wound by a conductive coil. When any rotor core set faces the stator cores in the axial direction, the rotor cores in other sets and the stator cores are staggered in the axial direction; and when a plurality of stator teeth of any stator pole set face the rotor teeth in the circumferential direction, the stator teeth of the stator poles in other sets and the rotor teeth are staggered in the circumferential direction. According to the double-shaft motor, screw rods or transmission gears are not employed so that the efficiency and the precision are high.
