Holding conceptA magnetic circuit provides holding force through a suitable ferromagnetic workpiece.
02 / HOW IT WORKS
How Does an Electro-Permanent Magnetic Chuck Work?
An electro-permanent design uses a controlled electrical pulse to change magnetic state; holding does not require continuous energization after switching. Release permission and state feedback are essential in automated setups.
Check switching sequence, controller interface, feedback and mechanical stops for each machining operation.
01Pulse switchingThe part must be sufficiently magnetic; many non-ferrous materials cannot be held directly.
02Feedback & interlockFlatness, surface condition and effective pole coverage affect real holding performance.
03Contact & supportCutting loads and lift or sliding forces must be checked before selection.
ENGINEERING FEATURE / PULSE CONTROL
Electro-Permanent Magnetic Chuck Switching and Machine Interlocks
The controller should only permit a release under defined machine conditions. Confirm PLC interfaces, clamp-state signals, pulse supply and procedures for a power interruption.

Magnetic holding is only part of the automation system.
Mechanical stops, contact conditions and safety logic also determine suitability.
03 / PERMANENT CHUCK SELECTION
How to Select an Electro-Permanent Magnetic Chuck
Start with ferromagnetic contact area, required switching arrangement and machining loads. Then review pole geometry, control interfaces and whether a single chuck or multiple zones are appropriate.

A different integration.
For mold bases and steel fixtures, tool access and locating supports may be more decisive than the magnet size. Machine-specific setups should account for lateral cutting force and controlled release.
