Turning Electrical Power into Mechanical Work

Presentation Agenda

• Discuss how a Solenoid Works

• Show some different types of Solenoids

• Discuss Applications for Solenoid use.

• Introduce Web Resources

How a Solenoid Works.

1. Apply Current2. Magnetic Field

Builds3. Stop and Plunger

Become Attracting Magnets

4. Magnetic Force Drives Plunger to Stop

Basics Types of Solenoids

• Push

• Pull

• Clapper

• Rotary

• Open

• Closed

Types of Solenoids

Pull Solenoids• Force is Directed Back

towards Solenoid.

Push Solenoids• Force is Directed

AWAY from Solenoid

Types of Solenoids

Clapper Solenoids• Typically Force

application can be the same as a Push or Pull

• Greater amount of End Force/Hold Force

Types of Solenoids

Rotary Solenoids• Apply a Torque over a

range of Rotation.

• Every Company has different ways to obtain the rotary motion.

Types of Solenoids

Rotary Solenoids• Other Configurations:

Types of Solenoids

• Open Frame Solenoids • Closed Frame Solenoids or Tubular Solenoids

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

Typical Solenoid Applications

• Rotary Solenoids– Sorting Machines

– Shutter Actuators

• Characteristics– Strokes from 5° to 90°

– As Stroke Increases

Starting Torque

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
