Patent number: 11651883Abstract: A switchable permanent magnetic unit is disclosed. The unit comprises: a housing, first and second permanent magnets, and a conductive coil. The first magnet is mounted within the housing and the second magnet is rotatable between first and second positions and mounted within the housing in a stacked relationship with the first magnet. The unit generates a first level of magnetic flux at a workpiece contact interface when the second magnet is in the first position and a second level of magnetic flux at the interface when the second magnet is in the second position, the second level being greater than the first level. The conductive coil is arranged about the second magnet and generates a magnetic field. A component of the conductive coil's magnetic field is directed from S to N along the second magnet's N-S pole pair when the second magnet is in the first position.Type: GrantFiled: June 7, 2021Date of Patent: May 16, 2023Assignee: MAGSWITCH TECHNOLOGY WORLDWIDE PTY LTD.Inventors: David H. Morton, Thomas R. Whitt, Michael H. Reed, Michael C. Blanchard
