Rotary Solenoids

The design of rotary solenoids is derived from the push-pull solenoid, incorporating a specially designed plunger with an angled profile. The internal structure uses inclined surfaces to convert the plunger’s linear motion into rotary motion. Three helical grooves, known as “ball races,” are precisely machined into the housing and armature plate.

These ball races serve two functions: they convert linear motion into rotary motion and provide a secondary bearing system to support the rotational movement of the solenoid.

• The specialized ball-race design provides consistent torque output, while different duty cycles can be selected to achieve different torque levels.
• An optimized coil design maximizes the available magnetic force within a compact structure.
• The extremely short magnetic circuit maximizes torque output and enables rapid response upon energization.
