Permenent Magnetic Lifter For Hot Steel Roll Coil Magnetic Lifting
Device
What is electro permanent magnetic technology ?
Loading Capacity: customized or 300kg
Electro permanent magnet technology is via electricity to control
the magnetic field lines of the permanent magnet material, which
express with magnetic force(magnetized state) or non-magnetic
force(demagnetized state). It is an innovative application
technology that can attract or release material independently.
Magnetized state: Electromagnetic coil with instantaneous
excitation current, which control the magnetic field state
switching of reversible magnetic material, so that the magnetic
field covering the surface of the magnetic poles and bring strong
adsorption force. As the magnetic field form a closed loop,no
magnetic loss, work with no heat, no noise, no energy consumption
features(as shown in Figure 1.1)
Demagnetized state:in the magnetized state, the electromagnetic
coil once again instantaneous excitation current, the built- in
circuit to change the reversible magnetic field, so that the
magnetic field converged inside the permanent magnet, and the
magnetic pole surface no longer have magnetic field, the material
is released.
| Electro Permanent Magnet VS Electromagnet |
| SEQ | Compare content | Electro Permanent Lifting Magnet | Electromagnet |
| 1 | Magnetic source | Permanent magnet Material: Reversible magnet steel, fixed magnet | Electricity: Magnetic field generated by Current through the coil |
| 2 | Principle mechanism | The magnetic field is turned on or off by an instantaneous current | Power on generated magnetic field, power off no magnetic field |
| 3 | Security | All steel surface, oil&water -proof, no aging issue | Epoxy resin sealed, may occur aging and shedding issue in 5years
later, need repair |
| 4 | Reliability | The suction is constant and does not attenuate over time | Suction is influenced by the heat caused by current, the coil is
easy aging if use long time |
| 5 | Durability and maintenance | Permanent magnet no magnetic attenuation, magnetic module is
maintenance-free. | Internal coil aging fast, the UPS battery need to be replaced
regularly, need to prepare the accessories. |
| 6 | Operating costs | Only in the moment of magnetization and demagnetization need
electricity, no need power,during working ,save energy more than
95% | Need long-term electricity power during working, big power
consumption, commonly known as “electric tiger” |

FAQ
1. How can i place an order?
Please provide the details of your requirements as clear as
possible. So we can send you the offer at the first time.
For designing or further discussion, it is better to contact us
with Skype / email / phone, in case of any delays.
2. What's the Difference Between Electromagnet and Electro-permanent
magnet?
Both industrial magnets are electrically switched on/off. The main
difference lies in 2 points.
First, electromagnet works on consistent electric power; if cutting
off the power supply suddenly, it losses magnetic force. What
distinguishes electro-permanent magnet from electromagnet is that
the former does not use electricity during working. If cutting off
the power, it can remain holding/lifting/gripping/clamping of the
load.
Second, due to continuous power input, electromagnet has heat
generation which might affect its workholding effectiveness during
machining. Whereas that is no problem to EPM.
3. How about the warranty ?
We have 1 year warranty and lifelong maintenance.
4. What is your terms of delivery?
We accept EXW, FOB, CFR, CIF, DDU, DDP, etc. You can choose the one
which is the most convenient or cost effective for you.
