  • Actuator capable of performing rational motion
    Patent number: 11398331
    Abstract: An actuator includes a first magnet whose magnetic pole surface has an N pole and a second magnet whose magnetic pole surface has an S pole. When current flows from one end of a first wiring to the other end, the current circulates in one direction at least partially on the first magnet in a first area, while it circulates in a direction opposite to the one direction at least partially on the second magnet in the first area. When current flows from one end of a second wiring to the other end, the current circulates in the direction opposite to the one direction at least partially on another first magnet in the second area, while it circulates in the one direction at least partially on another second magnet in the second area.

  • ACTUATOR
    Publication number: 20200126703
    Abstract: An actuator includes: a magnet structure including first and second areas, a first magnet whose magnetic pole surface has an N pole and a second magnet whose magnetic pole surface has an S pole; and a circuit board including first and second wirings. When current flows from one end of the first wiring to the other end, the current circulates in one direction at least partially on the first magnet in the first area, while it circulates in a direction opposite to the one direction at least partially on the second magnet in the first area. When current flows from one end of the second wiring to the other end, the current circulates in the direction opposite to the one direction at least partially on the first magnet in the second area, while it circulates in the one direction at least partially on the second magnet in the second area.
