摘要： The present disclosure relates to an actuator. The actuator includes at least two iron cores, each iron core including a pole extending in a first direction parallel to a direction of gravity; a permanent magnet disposed between the at least two iron cores so as to generate a magnetic field along a shape of a combination of the at least two iron cores arranged so as to be adjacent to each other in a direction not parallel to the first direction; and a winding wound around the pole of each of the at least two iron cores.

摘要： A motor device includes a stator assembly including a first magnetic coil including first windings wound around an outer face and an inner face of a first support and in a central-axis direction thereof; and a second magnetic coil including second windings wound around a surface of a second support inside or outside the first support and in a circumferential direction thereof; and a rotor assembly including a plurality of first permanent magnets; and a plurality of second permanent magnets including first and second extending magnets magnetized in an opposite direction to a magnetized direction of the first permanent magnets, wherein each of the first and second extending magnets has a length greater than each of the first permanent magnets, wherein the first and second extending magnets are respectively disposed in a first end area and a second end area opposite to each other of the rotor assembly.
