  • Patent number: 11446828
    Abstract: A parallel type integrated actuator is proposed. The actuator includes: a driving unit composed of a plurality of motors, each motor being stacked successively in a longitudinal direction of the driving unit, each motor having a stator fixed to a position outside the driving unit and a rotor positioned inside thereof, each motor rotating relative to each other; a plurality of shafts; a heat sink housing having a cylindrical shape formed around the outer surface of the driving unit, and having an inner circumferential surface thereof thermally connected with the plurality of stators and a plurality of flow paths formed on the outer circumferential surface thereof; and a blower fan installed on one end side of the driving unit, provided with a wing part disposed to be adjacent to one end side of the heat sink housing, wherein rotation generates convection for heat exchange.

  • Patent number: 11130245
    Abstract: A parallel type integrated actuator is proposed. The actuator includes: a driving unit composed of a first motor, a second motor, a third motor, and a fourth motor; a first shaft, a second shaft, and a third shaft, each shaft being inserted into each other through a hollow structure and forming a co-axis, each shaft being capable of rotating relative to each other in an inserted state, and each shaft having the other end part thereof extending outside the driving unit; an distal end part disposed outside the driving unit and on which an actuator is mounted; a first link part, a second link part, and a third link part allowing the distal end part to rotate in pitching, yawing, and rolling directions; and a universal link part connecting the fourth rotor, which is a rotor of the fourth motor, and the distal end part to each other.
