During the operation phase, when the magnetic force is active, the product is permanently magnetized so that nothing can alter its state except for a demagnetization electrical pulse. For example: When a permanent-electro product is magnetised, it can be held this way indefinatly, even if the power is disconnected and the cables are unplugged. In order to demagnetize it, simply connect the power again and send a demagnetization pulse. This saves electricity and ensures there is no danger of parts being dropped in the event of a power failure.
The EGM can handle alternating between different workpieces with minimal set-up time and without the constricting contours of gripper fingers. Due to the variable number of magnet pole pairs, optimum adaption to individual applications is ensured.
