5 Applications of Eddy Current Brakes

Eddy current braking is a state of the art braking technology that has both economic and risk management advantages. This unique braking technology takes the simple function of magnetic and non-magnetic forces and turns it into a high tech masterpiece. Using these forces as a braking mechanism stems from the purposeful generation of eddy currents in order to slow a movement. Eddy currents are formed when a conductor moves through a magnetic field, which generates opposing forces that swirl within the conductor. This reaction between forces provides the perfect conditions for smooth deceleration.

Eddy current braking gets its name from the swirling motions within its conductor, just like that of an eddy current in a river. As an innovative form of technology, eddy current braking has many reputable qualities. It is an ideal feature in many forms of machinery because of its absence of physical contact between internal components, which allows eddy current brakes to be very low maintenance. Low maintenance makes for few replacements, which means more money in your pocket.

The risk management improvements and economic advantages that accompany the eddy current brake has made it a popular choice among engineers when developing new technologies or improving the old. This intricate network of magnets is used more commonly than you might think. Recognizable uses for eddy currents are all around us. They exist in the home and in the work place. Here are 5 familiar applications of the eddy current brake.


1. Gym Equipment

One of the most common places we may see eddy currents at work is while we’re putting ourselves to work. Exercise equipment utilizes this innovative technology in many ways. Modern work out machines use eddy currents to create a smooth transition between resistance levels and make for low maintenance machinery. This use diminishes harmful and abrupt changes in pace which allows for a more enjoyable work out experience as well as producing high quality machines.

Popular equipment such as stationary exercise bikes are a great example of eddy currents in action. Programming the bike to simulate an “uphill” climb increases the drag between the non-magnetic conductor and the permanent magnet in the bike making it more difficult to keep peddling. By continuing to increase the incline the eddy currents become stronger and stronger and continue to create a more difficult work out.

Eddy current braking can also be found in rowing machines. Rowing machines provide eddy currents to match the resistance implemented by the user, meaning the harder you pull the more resistance you’ll experience. This is a unique way of using this kind of technology within work out equipment. The magnets are used to mimic the intensity of pushing an ore through water. The person using the machine gets to experience the strength of eddy currents and the magnets associated with the braking technology in a hands on way.

This same idea is used in elliptical machines. Using eddy current resistance, which provides heightened walking and stepping machine results, increases the difficulty level of an elliptical and allows for a better work out. Similar to the machines previously mentioned, there are many other uses of eddy current brakes used in common work out machinery. This application is a modern use of eddy currents and has contributed to the mainstreaming of eddy current brakes in everyday life.


2. Industrial Equipment

Since the creation of eddy current braking technology, they have been adopted into many forms of useful technology and more importantly, industrial use. Power tools and large industrial machinery use this technology for several applications. One of the main uses for eddy current breaking is in emergency shut off. Industrial factories and even common power tools have concerns with safety, which makes emergency shut off a must have. Moreover, if a power tool such, as a power saw or electric drill are shut off, the eddy currents kick in and safely bring the machine to a halt. This type of braking is used within the machine even in everyday use by forcing the mechanism to stop spinning. This is a fascinating way eddy currents are applied to everyday items that we otherwise wouldn’t suspect.

Just as we wouldn’t suspect eddy currents to be used in run of the mill power tools, they are actually used in common home features as well. We all have meters on our houses that are constantly recording how much power we use everyday. Although it may seem like an unlikely place to find complex magnets at work, electromechanical meters are perhaps the most common place to find eddy current technology. The meters are put into use every time you use energy using the unique network of magnets to propel a disk within which is then recorded by the numbers on the meters exterior. This may not be one of the most tangible uses of eddy current technology, however, it is the common and the most used. Eddy currents are in many forms of industrial equipment. Power tools and electromechanical meters are perhaps the most popular.
