Permanent magnets are used in many sorts of devices. They are applied in many electromagnetic transducers – like, for example, electric machines and measurement instruments. Nowadays a new generation of sensors, especially position sensors, are fitted with permanent magnets. Different types of sensors and different working environments require the application of permanent magnets with parameter...

The purpose of the newly constructed 8 GeV transfer line is to provide a reliable interconnection of the Booster and the Main Injector. This transfer line is constructed from the combination of the Permanent and Electro-magnets. We present data obtained during the commissioning along with our experience of combined function permanent magnets , DC operation of the electro-magnets and optics mode...

Low coercivity is the main disadvantage of RE-Fe-B permanent magnets containing highly abundant rare earths (RE: La, Ce) from the application point of view, even though they exhibit many cost and resource advantages. In this work, an industrial mixed rare earth alloy (RE100 = La30.6Ce50.2Pr6.4Nd12.8) with a high amount of the more abundant elements was adopted to fabricate RE-Fe-B permanent mag...

We explored the possibility of Pr-Fe-B and (Pr0.75Ce0.25)-Fe-B based hot-deformed magnets as magnetic field source for cryogenic refrigeration. Thanks to elimination spin reorientation effect in rare earth (RE)-Fe-B system, magnet shows a large remanence µ0Mr = 1.75 T with coercivity 7.4 at 20 K. To our surprise, even higher 1.76 4.8 The measured maximum energy product anisotropic is 612 kJ/m3 ...

Permanent magnet (PM) machines with tooth coil windings are designed and analyzed. We study how the slot wedge material affects the behavior of PM losses when using tooth coil windings, which generate a significant air gap flux density harmonic content. The losses and cogging torques of a surface permanent magnet rotor and an interior permanent magnet rotor are compared in no-load and load situ...
