Contents | Electro Permanent Magnet System | Electromagnet System |
The source of the magnetic force | From permanent magnets :NdFeB, AlNiCo | Produced by the electrical current flow |
Magnetization | Two kinds of magnetization, permanent and electromagnetic, both controlling the work load at the pole face | The electric current only controls the work load at the pole face |
Demagnetization | The interaction between the magnets removes the magnetic force controlling the work load | Isolation of the electric supply removes the magnetic force controlling the work load |
Safety | No electricity is consumed during the working period. Electricity shutdown won’t affect the operation of the magnet system or the magnetic latching of the work load. | Electricity is essential for the operation of the magnet. When in shutdown, the magnetization will stop. The work load may fall down without a battery backup supply. |
Reliability | No natural or electrical factors affect the magnet while it is operation and the reliability is quite stable. | An increase in temperature due to electric current flow or ambient temperature, may affect the operation of the magnet, and the coil or the electrical controls could open circuit or burn out. It is not as reliable. |
Maintenance | Minimum maintenance is required and the running cost is low. | The coils and battery need to be tested periodically and the cost can be expensive. |
The Operational Cost | No electricity is consumed while operating the magnet. The total electricity consumption is 5% of the electromagnetic systems. | The electricity consumption is quite large and the cost is expensive if used for long periods of time. |
Lifting weight/ Actual Weight Comparison | High:- A 4200kg electro permanent magnet can lift 15 tons. | Low:- A 8700 kg electromagnet can lift 15 tons. |
