Robotized Surface Mounting of Permanent Magnets

Robotized Surface Mounting of Permanent Magnets

Using permanent magnets on a rotor can both simplify the design and increase the efficiency of electric machines compared to using electromagnets. A drawback, however, is the lack of existing automated assembly methods for large machines. This paper presents and motivates a method for robotized surface mounting of permanent magnets on electric machine rotors. The translator of the Uppsala Unive...

Floating Chip Mounting System Driven by Repulsive Force of Permanent Magnets for Multiple On-Site SPR Immunoassay Measurements

We have developed a measurement chip installation/removal mechanism for a surface plasmon resonance (SPR) immunoassay analysis instrument designed for frequent testing, which requires a rapid and easy technique for changing chips. The key components of the mechanism are refractive index matching gel coated on the rear of the SPR chip and a float that presses the chip down. The refractive index ...

Mounting of Surface Mount Components

Over the past few year, electronic products, and especially those which fall within the category of Consumer Electronics, have been significantly reduced in physical size and weight. Products such as cellular telephones, lap-top computers, pagers, camcorders, etc., have been reduced by as much as 3/4 of their original introductory size and weight. The most significant contributing factor to thi...

Nonlinear Numerical Simulation of Permanent Magnets

Rare earth permanent magnet models are commonly used in the design of undulators and wigglers. Normally the operating point of the magnet in the B vs. H diagram corresponds to a linear reversible characteristic. The region of linearity is strongly dependent on the temperature. The operation of part of the magnet blocks in the region of non-linearity is responsible for the so-called irreversible...
