Magnet Assemblies typically have higher magnetic force in contrast to a standalone magnet. The flux conducting elements (steel) assembled to the magnet often are integral to the magnetic circuit. These elements utilizing magnetic induction will enhance the performance of the assembly’s field, focusing it to a predetermined direction.
Magnetic assembly’s performance levels increase when the assembly is in direct contact with the work-piece. Small gaps can dramatically impact the magnetic force between the assembly and the work piece. These gaps most commonly designed are “air-gaps”, calculated at pivotal distances to regulate the amount of force. Coatings or any other form of capsulation is also considered a gap and has a similar effect.
Mounting magnetic assemblies are achieved by various methods. Common techniques are:
- Press-fit (interference)
- Mechanical fasteners.
The Press-fit assembly will typically utilize a centerless-ground brass sleeve for insertion into a bore. The Mechanical fastener assembly is achieved through traditional drilling & tapping a hole in the assembly for mounting the fastener.
