This document discusses how solenoids work to convert electrical power into mechanical work. It describes how applying a current generates a magnetic field that attracts a plunger, creating motion. Different types of solenoids are presented, including push, pull, clapper, and rotary varieties. Common applications like valve actuators and sorting machines are reviewed. Size, stroke length, and force limitations of solenoids are also covered. Web resources for learning more about solenoids are provided.

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 
