1. Turning Electrical Power into
Mechanical Work

2. Presentation Agenda
• Discuss how a Solenoid Works
• Show some different types of Solenoids
• Discuss Applications for Solenoid use.
• Introduce Web Resources

3. How a Solenoid Works.
1. Apply Current
2. Magnetic Field
Builds
3. Stop and Plunger
Become Attracting
Magnets
4. Magnetic Force
Drives Plunger to
Stop

4. Basics Types of
Solenoids
• Push
• Pull
• Clapper
• Rotary
• Open
• Closed

5. Types of Solenoids
Pull Solenoids
• Force is Directed Back
towards Solenoid.
Push Solenoids
• Force is Directed
AWAY from Solenoid

6. Types of Solenoids
Clapper Solenoids
• Typically Force
application can be the
same as a Push or Pull
• Greater amount of End
Force/Hold Force

7. Types of Solenoids
Rotary Solenoids
• Apply a Torque over a
range of Rotation.
• Every Company has
different ways to
obtain the rotary
motion.

8. Types of Solenoids
Rotary Solenoids
• Other Configurations:

9. Types of Solenoids
• Open Frame Solenoids • Closed Frame Solenoids
or Tubular Solenoids

10. Typical Solenoid Applications
• Linear Applications
– Valve Actuators
– Latching/Switching
– Pushing/Pulling Objects
• Sorting
• Shutters
• Characteristics
– Size  as Force 
– Limited Stroke Lengths
• 5/8” is a Long Stroke

11. Typical Solenoid Applications
• Rotary Solenoids
– Sorting Machines
– Shutter Actuators
• Characteristics
– Strokes from 5 to 90
– As Stroke Increases
Starting Torque 

13. Conclusions
• Solenoids Convert Electrical Energy to
Mechanical Work
• Different Types of Solenoids for
Different Types of Applications
– Linear and Rotary
• Major Considerations
– Size
– Stroke and Force Limitations
