What are magnetic bearings and how they work

Industrial electric motors are the largest electrical end-use accounting for approximately 45% of global electricity consumption. Existing high-speed electric motor solutions without active magnetic bearings are inefficient and expensive to maintain. Electricity and maintenance costs represent more than 70% of the total lifecycle costs. As they operate at high speeds (above 10,000 rpm), they are often subject to failures and breakdowns, compromising the productivity…

Applications of active magnetic bearings

Active magnetic bearings (AMBs) have been used in the industry for more than 30 years. Various industrial applications are using high-speed electrical machines in their processes. With high rotational speeds (>10 000 rpm), these machines are often subject to failures and breakdowns. These failures are compromising the productivity and efficiency of the systems they drive.…

Benefits of active magnetic bearing system 

Active magnetic bearings (AMB) levitate the rotational part of the electric motor using electromagnetic forces. By levitating the rotor there is no metal-to-metal contact between the rotating and stationary parts. This significantly increases energy efficiency and reduces maintenance costs of high-speed motors. The need for high shaft speed is one of the factors that call…
