(Extract)
•Field strength decreases with distance to conductor ⇒Field strength decreases in the depth of the magnet
⇒Risk of incomplete saturation in the depth of the magnet
⇒Field strength on the surface of the magnet much higher than the
required saturation field strength

•Principle
•Magnetizer: modular design, specified by
–Energy
–Max. charging voltage –Max. current
–Min. charging time (cycle time)–Shape of current pulse –
Input power
•Magnetizing fixture: usually specialized based on the product •
FEM analysis defines the specs above
Magnetizer Capacitors Electric energy
Magnetizing fixture Inductivity
Magnetic energy
•Actual standard (axial): Bitter coil
Principle Photo Bitter coil under construction
Presentation MAGSYS
Basics25
•Actual standard: Bitter coil
–Mechanical fixing of conductors
Æhigh field strength (forces)
possible, long lifetime
–No epoxy Ægood heat-transfer
via copper Æshort cycle time
with air cooling
–Higher costs
–R und L not very variable
