notably thin-walled ring magnets that proved ideal for use in small motors. The development of neodymium–iron–boron permanent magnets has allowed the miniaturization of motors and hard disk ...

President Donald Trump and First Lady Melania Trump attended the Commander-in-Chief Inaugural Ball and the Liberty Inaugural Ball in Washington on Monday night.

Two companies have collaborated to expand the product range of magnet-free electric motors to upper-segment applications.

These stator teeth are used for the coils, which align with either a permanent magnet ring, a soft iron core or both on the rotor. Much like with other electric motors the stator coils rotate the ...

The magnetic field from the coil induces an opposite field in the copper ring that is out of phase ... and the same technique can help AC motors self-start as well as hold in relays driven by ...
