Today, most electric machines operate with radial flux (RF). Magnax offers a new concept, though—a machine that operates with axial flux (AF). Figure 1 provides a comparison of the RF and AF ...

Two German physicists have reimagined how to create powerful and uniform magnetic fields using compact permanent magnets. By overcoming the limitations of the well-known Halbach array, which works ...

Rare-earth-free permanent magnet generators (PMG) for offshore wind turbines with nameplates of 20MW are expected to be a reality “within three years”, following trials of a new-generation concept at ...

Growing global requirements for higher power plant performance are shaping the design and manufacture of today’s generators. Industry demands for higher reliability, efficiency and cost-effective ...

• Magnetic bearings support rotating shafts in five axes without solid or fluid lubricants. • Advances in electronics allow previously bulky controllers to mount on or near rotating machinery. • ...
