Part 1: What is a rotary solenoid actuator ?

The rotary solenoid actuator is similar to the motor, but the difference between is that the motor is can rotate 360 degree in one direction, while the rotating rotary solenoid actuator cannot rotate 360 degree but can rotate to a fixed angle. After the power is off, it is reset by its own spring, which is considered to complete an action. It can rotate within a fixed angle, so it is also called a rotating solenoid actuator or an angle solenoid. As for the rotation direction, it can be made into two types: clockwise and counterclockwise for the project need.

Part 2: The structure of rotary solenoid

The working principle of the rotating solenoid is based on the principle of electromagnetic attraction. It adopts an inclined surface structure. When the power is turned on, the inclined surface is used to make it rotate at an angle and output torque without axial displacement. When the solenoid coil is energized, the iron core and the armature are magnetized and become two magnets with opposite polarities, and electromagnetic attraction is generated between them. When the attraction is greater than the reaction force of the spring, the armature begins to move toward the iron core. When the current of solenoid coil is less than a certain value or the power supply is interrupted, the electromagnetic attraction is less than the reaction force of the spring, and the armature will return to the original position under the action of the reaction force.

Part 3: Working principle

When the solenoid coil is energized, the core and the armature are magnetized and become two magnets with opposite polarities, and electromagnetic attraction is generated between them. When the attraction is greater than the reaction force of the spring, the armature begins to move toward the core. When the current in the solenoid coil is less than a certain value or the power supply is interrupted, the electromagnetic attraction is less than the reaction force of the spring, and the armature will return to the original position. The rotating electromagnet is an electrical appliance that uses the electromagnetic attraction generated by the current-carrying core coil to manipulate the mechanical device to complete the expected action. It is an electromagnetic element that converts electrical energy into mechanical energy. There is no axial displacement when rotating after power is turned on, and the rotation angle can reach 90. It can also be customized to 15°, 30°, 45°, 60°, 75°, 90° or other degrees, etc., using CNC-processed spiral surfaces to make it smooth and unstuck without axial displacement when rotating. The working principle of the rotating electromagnet is based on the principle of electromagnetic attraction. It adopts an inclined surface structure.

5.5 rotary solenoid selection

When selecting rotary solenoids, buyers should consider application requirements such as maximum rotary stroke, axial stroke, and response time. The maximum rotary stroke is the full rotary travel in angular units. The axial stroke is the axial travel of the solenoid during actuation, as measured in units of distance. Response time is the time required to move full-stroke under no-load conditions. If you need more information and help from Dr. Solenoid, just send us a note with your based requirement.
