Rotary Solenoids
Rotary solenoids convert electrical energy into rotary motion, providing precise angular displacement. Cixin Electromagnetic manufactures custom rotary solenoids with tailored angle, torque, and response time for your specific application since 2011.
Key Features
- Precise rotary motion: Controlled angular displacement up to 90° or more
- High torque density: Strong torque output in a compact package
- Fast response time: Millisecond-level response for high-speed applications
- Custom angle and torque: Engineered to meet your exact specifications
- Bidirectional rotation: Optional bidirectional models available
Working Principle
Rotary solenoids use an electromagnetic coil to create a magnetic field that interacts with a rotor (armature) to produce rotary motion. When current flows through the coil, the rotor rotates to a specific angular position. The rotation angle and torque can be customized by adjusting the coil design, rotor geometry, and magnetic circuit.

Design Considerations
When selecting a rotary solenoid for your application, consider the following factors:
- Torque requirement: Calculate the torque needed at the required rotation angle
- Rotation angle: Determine the required angular displacement (15°, 30°, 45°, 60°, 90°, etc.)
- Response time: Faster response requires higher power and may affect duty cycle
- Duty cycle: Continuous operation requires a solenoid designed for 100% ED
- Environmental conditions: Temperature, humidity, and contaminants can affect performance
