The electro permanent Magnetic controller systems using electrical Power only in magnetizing and demagnetizing process, after 0.1～2 seconds when magnetizing and demagnetizing process successful , the electric energy without needs and the connection between electro permanent Magnetic and controller is completely disconnected.

While electro permanent Magnetic system in Adsorption process, the electrical power without need and using Permanent magnetic force to adsorption magnetic material. Being avoid of electric control system in sudden power-off or connecting cable damage situation when the magnetic force will loss and appear to be sucking the risk of falling. The Electric permanent magnetic maximum force can up to 16kg/cm² powerful suction. Because of the magnetic force No decreases with time, the EPM system Have a great security.

The Electric permanent magnet without install any moving parts inside. Consider the Coil only needs short-time working and no fever phenomenon appear, the Electro Permanent Magnetic System without repair, strong practicality and very reliable. The Coil insulation comprises four layers of insulation and the insulation resistance reaches more than 1000MΩ, no leakage phenomenon occur.
