Generator heads and alternators convert mechanical ... To create the magnetic field, either permanent magnets are used—called a magneto, or an electromagnet that requires some form of power. Since the ...

Two great minds in permanent-magnet-free motor design ... supplier has been using wireless induction with a rotor configuration it calls the Magnet-free Contactless Transmitter (MCT).

They include individual magnets, bulk magnet materials, magnetic assemblies, magnetic sweepers, magnetic lifts, magnetic sheet handlers, magnetic retrievers, and permanent / electromagnet combinations ...

Traditional electric vehicle motors rely heavily on rare earth magnets, particularly those containing neodymium. These ...

The short version is that you’ll need to machine a new rotor and fill it with the neodymium magnets salvaged from hoverboard motors. A custom built alternator rotor is the key to the project.

Luckily, there’s more than one way to make a magnet, and it may soon be possible to build permanent magnets as strong as neodymium magnets, but without any rare earth metals. In fact ...

Even today, it remains the most powerful permanent magnet in the world. The two researchers — Japanese engineer Masato Sagawa and American metallurgist John Croat — have been awarded the 44th ...

they are not repelled they lose most or all of their magnetism when they are removed from the magnetic field This means that you can only show that an object is a permanent magnet by checking if ...

From the beginning, IMA has used a permanent magnet AC synchronous motor which is both compact and efficient. The stator is fixed to the internal perimeter of the case while the rotor is bolted to ...

A permanent magnet is always magnetic. It has an invisible magnetic field. Only certain materials, such as iron, feel a magnetic force. Permanent magnets can come in lots of different shapes and ...

Neodymium-iron-boron is the strongest permanent magnet material in wide-scale use today Name a technology that is all around us, underpins our modern way of living but is hardly recognised for its ...

Rubio released a statement in support of making daylight saving time permanent just days ahead of the twice-annual switch from daylight saving time to standard time, which happens Sunday.
