In the age of environmental consciousness, companies operating across different industries are trying to build and use machines that have no negative consequences on the environment. In a fit to achieve this objective, companies are rediscovering fundamental principles of physics –magnetic bearings. Magnetic bearings have multiple benefits and these include reduced friction, minimized vibration and enhanced reliability plus the ability to monitor and diagnose. All these are present without the disadvantages associated with lubricants. The basic principle behind magnetic bearing is magnetic levitation that is used to support heavy loads. There are various types of magnetic bearings. One of them is passive magnetic bearings which do not require any power source but are relatively difficult to design when compared to active magnetic bearings which require a control system to monitor the load as well as a continuous power source. One of the key drivers is of the magnetic bearing industry is their increasing use in aerospace and defense industry because of the cost efficiency these magnetic bearings possess.
There have been many developments in the magnetic bearing market. Traditionally, the magnetic bearings were very expensive but due to manufacturing advances that involved integration and standardization of the bearings in the device, the overall cost has reduced significantly. The engineering effort has also been greatly reduced. All these factors have resulted in the magnetic bearings to become more economical. Recent developments have resulted in the overall reduction in the physical size of the bearing by nearly one third. Increasing the amount of steel in the bore whilst simultaneously reducing the steel in the overall body has greatly completed in achieving a reduced size. The length of the radial magnetic bearing has also been reduced. The magnetic bearing also consists of a controller the original size of which was that equal to a refrigerator. However, with recent trends and developments this size now has been reduced to that of a Laptop. Recent technology has allowed the remote to be integrated along with the bearing itself which eliminates the need for a separate remote. On the basis of speed, the market is classified into three segments. These include up to 50,000 RPM, 50,000 RPM to 100,000 RPM and 100,000 RPM & above. The market is dominated by bearings having a maximum speed of 50,000 RPM which are used many end users for multiple uses. Speaking in terms of geography, Asia – Pacific is expected to show the highest growth rate because of number of humongous construction projects and increasing foreign investments in the region.
With the advancements in technology, magnetic bearings today offer got a greater number of machines and applications. Innovations related to design that relate to miniaturization, standardization and integration have resulted in greater usage of magnetic bearings for many existing and new machinery products. The growth in this sector would also be complemented by rising concerns over environmental degradation.
