What is a Rotary solenoid?

A rotary solenoid is an electromechanical device that produces rotational motion, unlike traditional solenoids that generate linear movement. When current flows through the coil, a magnetic field is created, which induces the rotor to rotate by a specific angle. This rotational movement is controlled by switching the current on and off, making it ideal for applications that require precise positioning and timing.

Rotary solenoids are widely used across various industries due to their simple structure and high reliability. They are applied in automation equipment, medical devices, aerospace, telecommunications, and more. Specific uses include valve control, switching mechanisms, and paper feed systems in printers and office equipment. Additionally, rotary solenoids have low wear, a long lifespan, and are easy to maintain, contributing to efficient machine design. They play a crucial role in situations that demand precision and high-speed operation.

Application of Rotary solenoid

１．Valve Operation Control: Rotary solenoids are used to open and close valves that control the flow of liquids or gases. By switching the current on and off, the valve opens or closes automatically, allowing for precise flow control.
２．Medical Devices: In the medical field, rotary solenoids are used in devices that require precise positioning, such as in drug delivery systems or diagnostic equipment components.
３．Paper Feed Mechanisms in Printers and Office Equipment: Rotary solenoids control the mechanisms that feed paper in printers and copiers, ensuring accurate paper movement and positioning.
４．Aerospace Industry: In aircraft and spacecraft, rotary solenoids are integrated into control systems to provide precise actuation and position control for various functions.
