Electromagnetic Eddy Current Brake: Types & Applications!

 Eddy-current brakes, commonly referred to as electric ones, are a substitute for conventional hydraulic ones. This device uses an electromagnetic force between an electromagnet and the surrounding conductive material, such as eddy current induced in that for electromagnetic induction, to slow down or stop a moving body by dissipating its kinetic energy as heat and braking force. In today's world, electromagnetic eddy current brake is used in numerous applications.

Types of Electromagnetic Eddy Current Brake

 

Linear Eddy-Current Brakes


Here, the magnet is maintained at a constant distance from the rail rather than touching it.   

As opposed to a disc brake, which physically touches each segment of the disc through the brake, this linear brake only goes through its magnetic field, which results in less heat production, less noise, no wear-and-tear, and a higher braking power than traditional disc brakes. 

 

For emergency braking, the eddy current brake is a preferable choice. This type of braking is used on contemporary roller coasters. They use permanent magnets rather than electromagnets to avoid the problems caused by power outages, which eliminates the requirement for a power supply. This application does not offer the same ease of braking power adjustment as electromagnets.  

  

Disk Eddy-Current Brakes 


A conductive non-ferromagnetic metallic disc (rotor) fastened to the wheel axle makes up a disc eddy current brake. These are used in power tools like circular saws and transportation like trains to halt the blade once the current is cut off promptly. These brakes heat up more quickly than a standard linear brake.  

  

Applications

  

This brake comes with many applications, a few of them are as follows: 

  

Power Tools & Equipment


One of its primary uses is for power tools and heavy industrial equipment to slow down or turn off in an emergency. When activated, these brakes may swiftly and without lag bring a large machine to a halt.

  

High-Speed Trains 

 

It is a tried-and-true method to reduce the jerking effect when slowing down a fast train while keeping the passenger's comfort in mind. Using technology, trains and commuters can go at higher speeds while maintaining higher safety standards.  

  

Exercise Equipment


Possibly the most normal electromagnetic eddy current brake could also be used at fitness centers or gyms.  

  

Amusement Park Rides

 

Eddy current brakes are installed in amusement park rides to provide stopping force in risky sporting equipment. Typically, this braking device is applied following a roller coaster leap or an Overspeed. When using the eddy current brake, the brake can slow down a roller coaster faster the faster it moves. This offers a high level of safety; with these brakes, quick switching and quick acceleration are possible, which are desirable features for riding at amusement parks.  

  

Conclusion

  

In an expanding world, electromagnetic eddy current brake technology is a helpful resource. A safer and more effective world is emerging as innovations are created. The innovations include roller coasters, industrial tools, entertainment, and transportation improvements. We may use the eddy current brake for many more things than we think in our daily lives. Pay attention to how this cutting-edge innovation is being used in everyday life!

Brushless DC Motors For Cars

Image
Electric cars are not as completely new as you would consider. Gustave Trouve , a French inventor, invented the first electric vehicle, a tricycle, in 1881. This was made feasible by Trouve's invention of the electric motor, which allowed him to lighten the weight of the engine's parts and produce an astounding amount of energy. Since then, engineers have worked tirelessly to develop electric vehicles. Many of these efforts, particularly those involving electric cars, concentrate on improving batteries. Today, brushless DC motors for vehicles are employed for more than just tricycles and cars. Less gasoline produces fewer greenhouse gas emissions and gives drivers more incredible gas mileage. But perhaps it's time to consider what made Trouve's tricycle so groundbreaking.    While an overall approach for enhancing electric vehicles should continue to include more robust electric storage devices, such as fuel cells or batteries, one crucial component is just now comi...

Comparison Between Hydraulic, Pneumatic, and Electromagnetic Eddy Current Brakes!

Image
When it comes to industrial breaks, you will get multiple options that are available for you in the market. These brakes include hydraulic, pneumatic, and electromagnetic eddy current brakes . The best choice for you depends on the location, preferred power source, purpose, and budget.    Compared to standard brakes, these three brakes work in the opposite way. In these brakes, pressure is applied to hold the brake rather than putting pressure to engage the brake. After the removal of the power supply, the spring releases & braking force is applied to the system. It will enable spring-applied brakes to build higher torque than standard brakes. Therefore, they are very reliable and safer for loads that are in linear motion or suspended.    Hydraulic Spring Applied to Brake   Hydraulic braking systems can have massive torque. These brakes are commonly used for emergency stopping, tensioning, and keeping heavy-weight industrial equipment and off-road vehic...

Difference Between Frameless & Housed Torque Motors!

Image
Direct-drive motors constitute an appealing alternative for all applications requiring high torque at low speed to drive rotary axis types. We are aware that every application has unique requirements and limitations, nevertheless. You can choose between torque motors with or without housing in the torque motor range.   Housed Torque Motor   A brushless servomotor in complete form, a housed torque motor has the same benefits of high torque density, accuracy, and dependability as a frameless torque motors . It provides a comprehensive solution for applications where it is not desirable to integrate the motor as an active component of the machine itself. When mounted and linked, this design enables protection of the motor against water spray and dust.    Frameless Torque Motor   The frameless design is perfect for OEMs who desire simple machine integration. This torque motor is packaged with two parts: a stator, which is directly fastened to your mac...
