EGM electro-permanent magnetic grippers offer energy-efficient handling of ferromagnetic workpieces. With high holding forces in a small form factor, large workpieces can be handled with a robot or gantry system precisely and reliably.
The function of the magnetic gripper bases on the combination of AlNiCo and neodymium magnets. The magnetic flux of the AlNiCo magnets passes the neodymium magnet in the deactivated state, and closes the magnetic circuit over the gripper base body made of steel. To activate the system, an electric current pulse is conducted through the coil, which reverses the polarity of the AlNiCo magnets accordingly.
The magnetic flux can not pass the Neodym magnets anymore and has to pass via the workpiece into the opposite pole, creating a holding force.
Advantages – Your benefits
- High holding forces at lowest space
for reliable part handling in compact machines - Low weight
for high dynamics in challenging applications - Reliable holding force maintenance
to ensure process reliable operation even in scenarios with emergency stop - Energy efficiency: electricity is only required for magnetization and demagnetization
for an economic and careful managment of resources - Variable number of magnetic poles and adaptation possibilities to any common robot
to ensure the optimum adaption to each application - Workpiece accessibility from five sides free from interfering contours
by unnecessary gripper fingers
Options and special information
- Control via external controller
Electrical control of the gripper takes place via the controller, which is separately available on request. The interface to the control unit is provided by digital I/O.
