Linear electromagnetic actuators are energy efficient devices that are more powerful than hydraulic pistons. Electromagnetic actuators essentially perform the same controlling motions, but they are a stronger and more flexible technology than the hydraulic pistons. As current goes through the wire, a magnetic field sets up around the wire. Coiling the wire creates a greater magnetic field which becomes stronger as there are more coils getting energized by the current.

When shopping for electromagnetic actuators price, you will have to make some decisions on how the actuator is going to work for you. Your information will need to be precise so that the electromagnetic actuator manufacturer can give you an accurate price quote. Below are some design choices that you must make:

1. Choose an electromagnetic actuator style of either English or metric format of measurement.

2. Set up a motion profile for distance and speed it must move.

3. Define the stroke length, orientation, load, moment, and thrust force.

The best contacts and resources to help you get it done

Customize your electromagnetic actuator

Electromagnetic actuator distributors can provide a standard model, but most users of industrial electromagnetic actuators will require some level of customization. Many electromagnetic actuator manufacturers provide free CAD software available as a download to aid you in your design. Of course, complete engineering services are available to customize your electromagnetic linear drives and electromagnetic actuated valves.

I recommend: If you need a cryogenic compatible electromagnetic actuator or non-standard stroke lengths, then consult with Island Components or Ultra Motion to help with customization.

Select multiple suppliers of linear electromagnetic actuators

It is always a good idea to have an electromagnetic actuators supplier list. You never know when your electromagnetic actuator will break down or whether you will need a part quickly. If your only supplier is out of stock, what will you do?

I recommend: Macron Dynamics designs and manufactures linear motion components and systems that meet all of the requirements for load, speed and precision necessary for industrial linear motion applications. Haydon Switch & Instrument sells a hybrid linear actuator that is quieter and more efficient than standard actuators.

Buy a rodless electromagnetic actuator from the manufacturers

If you need to save space, then consider buying a rodless electromagnetic actuator. Electromagnetic actuator distributors and manufacturers can provide rodless electromagnetic actuators that can handle extremely heavy loads and moments. The rodless actuator guides and supports the load throughout the entire stroke length.

I recommend: The rodless electromagnetic actuator is designed with a different bearing and load carrying techniques which allows it to control the bending moments easier. Contact Tolomatic and Precision Technology to purchase a rodless actuator.

Helpful advice for making the most of this Guide

• •  High speed electromagnetic actuators will probably break down at some point. Make sure you buy from a company who supplies a minimum of a one year warranty.
