Benefits of AMBs

Tolerance to Harsh Conditions  

Active magnetic bearings excel in extreme conditions, including high temperatures and contaminated environments. Their design eliminates direct contact between moving parts, reducing wear and preventing damage from dirt and debris. This makes them highly reliable in industrial settings where harsh conditions are the norm.   

For applications that require even greater protection, active magnetic bearings can be “canned” or sealed within a protective enclosure. This option further shields the bearings from external contaminants, ensuring long-lasting performance in the most challenging environments.  

Variable and High-Speed Operation 

Active magnetic bearings are perfectly suited for applications requiring variable and high-speed operation. They allow for limitless start-stop cycles, meaning the system can repeatedly start and stop without causing wear or reducing lifespan. Additionally, these bearings perform consistently, regardless of speed fluctuations, ensuring smooth operation even as speeds change. Unlike traditional bearings, active magnetic bearings do not impose any limitations on rotational speed, enabling machines to operate at their full potential without concerns about bearing constraints. 

Oil-free Operation

Active magnetic bearings excel in oil-free operation, offering a significant advantage for environments where oil use is restricted or entirely prohibited. These bearings operate without the need for lubrication, which means there’s no requirement for complex lubrication systems. This not only simplifies maintenance but also eliminates the risks associated with oil leakage or contamination. As a result, active magnetic bearings are particularly well-suited for applications where maintaining a clean, oil-free environment is critical, such as in clean rooms, vacuum systems, or food processing industries. 

Unique Dynamic Properties 

Active magnetic bearings offer unique dynamic properties that set them apart from traditional bearings. One of the key advantages is their ability to precisely adjust stiffness and damping, which can be easily measured and modified to suit specific operational needs. This flexibility allows for fine-tuning of the system’s performance, ensuring optimal rotor dynamics control. Additionally, active magnetic bearings can quickly correct unbalance conditions, leading to smoother and more stable operation. These capabilities make them ideal for applications where precise control and adaptability are essential. 

Low Energy Consumption  

Another standout benefit of active magnetic bearings is their remarkably low energy consumption. Due to their non-contact design, these bearings generate minimal heat, reducing the need for energy-intensive cooling systems. This efficiency translates directly into lower operational costs, as the system requires less power to maintain optimal performance. By minimizing energy usage and heat generation, active magnetic bearings offer a cost-effective solution that supports both sustainability and long-term reliability in demanding applications.  

No Mechanical Contact Between the Bearing Elements 

Active magnetic bearings (AMBs) operate without any mechanical contact between the bearing elements, which eliminates friction losses entirely. This contact-free design not only enhances efficiency but also significantly reduces wear and tear on the system. As a result, AMBs provide maintenance-free operation, greatly extending the lifespan of the equipment. Furthermore, because there’s no physical contact, these bearings produce very low noise and minimal vibrations, contributing to a quieter and more stable operating environment. This makes them an ideal choice for applications where reliability, longevity, and low operational disturbances are critical. 

Reduced System Footprint 

Active magnetic bearings eliminate the need for additional space typically required for a gearbox. This is because they use magnetic fields to levitate and stabilize the rotating shaft, allowing for direct drive systems. As a result, the overall system becomes more compact and streamlined. Additionally, by reducing mechanical contact and friction, active magnetic bearings significantly enhance system efficiency, leading to lower energy consumption and reduced wear and tear on components. This makes them an excellent choice for high-performance applications where space and efficiency are critical considerations. 

Build-in Condition Monitoring 

The condition monitoring system, equipped with built-in sensors, continuously collects data on the equipment’s status, enabling predictive maintenance. SpinDrive’s magnetic bearing technology seamlessly integrates with Internet of Things (IoT) services. It includes sensors and a controller that can be incorporated into online equipment condition monitoring systems. 

By analysing operational data, the system helps prevent equipment breakdowns and eliminates associated costs. The software platform processes data from the machine, allowing for comprehensive monitoring of not only the electrical machine itself but also the connected working tools and overall process performance. It tracks the operating hours of the magnetic bearing system and uses this data to predict maintenance needs more accurately, ensuring timely and precise maintenance actions.
