ROTARY RECIPROCATING DRIVE ACTUATOR - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240022154 titled 'ROTARY RECIPROCATING DRIVE ACTUATOR

Simplified Explanation

The abstract describes a rotary reciprocating drive actuator that includes a movable body with a shaft part and a magnet, a base portion with wall portions to support the shaft part, a core assembly with magnetic poles, a coil body, and a magnet position holding portion, and a sensor board with a sensor to detect the rotational angle of the shaft part.

  • The actuator consists of a movable body, base portion, core assembly, and sensor board.
  • The movable body has a shaft part and a magnet.
  • The base portion supports the shaft part and includes wall portions.
  • The core assembly is attached to one wall portion and includes magnetic poles, a coil body, and a magnet position holding portion.
  • The sensor board is attached to the other wall portion and has a sensor to detect the rotational angle of the shaft part.
  • The sensor board is positioned to face the other wall portion and detect the rotational angle.

Potential applications of this technology:

  • Robotics: The actuator can be used in robotic systems to provide precise and controlled rotary reciprocating motion.
  • Automation: It can be applied in automated machinery and equipment to enable efficient and accurate movement.
  • Automotive: The actuator can be utilized in automotive systems for various applications such as throttle control or valve actuation.

Problems solved by this technology:

  • Precise motion control: The actuator allows for accurate and controlled rotary reciprocating motion, enabling precise positioning and movement.
  • Compact design: The integration of the core assembly and sensor board into the actuator results in a compact and space-saving design.
  • Reference position definition: The magnet position holding portion in the core assembly helps define a reference position for the reciprocating rotation.

Benefits of this technology:

  • Improved efficiency: The actuator enables efficient and smooth rotary reciprocating motion, reducing energy consumption and improving overall system efficiency.
  • Enhanced accuracy: The sensor board accurately detects the rotational angle of the shaft part, ensuring precise control and positioning.
  • Compact and versatile: The compact design of the actuator allows for easy integration into various systems and applications.


Original Abstract Submitted

a rotary reciprocating drive actuator includes: a movable body including a shaft part to which a movable object is connected, and a magnet; a base portion including a pair of wall portions disposed to sandwich the movable object and support the shaft part; a core assembly including a core body including a plurality of magnetic poles, a coil body, and a magnet position holding portion to define a reference position of the reciprocating rotation, the core assembly being attached to one wall portion; and a sensor board that is attached to an other wall portion and on which a sensor configured to detect a rotational angle of the one end portion of the shaft part is mounted, in which the sensor board is disposed such that the sensor faces the other wall portion from an outer surface side of the other wall portion and detects the rotational angle.
