In the field of port transportation, permanent magnet synchronous generators have been widely used due to their excellent performance. From the perspective of loading and unloading equipment, permanent magnet synchronous generators play a key role in shore-based container cranes. As a drive motor, it provides strong power for the crane. Its working principle is based on the permanent magnet generating a rotating magnetic field in the stator winding, allowing the rotor to rotate synchronously with the magnetic field, thus achieving efficient conversion of electrical energy to mechanical energy. Since the permanent magnets are made of magnetic materials such as neodymium iron boron, no additional excitation is required, reducing energy loss, and compared to traditional asynchronous generators, efficiency can be improved by 15% - 20%. During actual operations, it can quickly respond to the lifting and translation commands of the crane, achieving precise positioning and efficient loading and unloading, significantly improving the efficiency of container handling and reducing operation time.

In the auxiliary power supply system of the port, permanent magnet synchronous generators are also indispensable. They can provide stable power supply for lighting, ventilation, and various monitoring equipment within the port. When facing peak electricity demand or sudden power needs, the rapid response characteristics of permanent magnet synchronous generators are highlighted, allowing for quick adjustments in output power to ensure the stability of power supply, avoiding equipment damage or abnormal operation due to voltage fluctuations. For example, when the demand for nighttime lighting increases significantly, it can promptly increase power generation to ensure that all areas of the port have sufficient lighting, ensuring safety during nighttime operations.

Additionally, port transport vehicles such as Automated Guided Vehicles (AGVs) are gradually adopting permanent magnet synchronous generators as their power source. This allows AGVs to consume less energy during operation and enhances their endurance. Moreover, the precise speed regulation performance of permanent magnet synchronous generators enables AGVs to flexibly adjust their speed according to different driving conditions and cargo weights, avoiding energy waste while ensuring smooth transportation, reducing the risk of cargo shaking and damage.

Looking to the future, with the advancement of the trend towards intelligent and green development in ports, permanent magnet synchronous generators will evolve towards higher power density, lower noise, and smarter control. By developing new types of permanent magnetic materials and optimizing motor structures, their performance will be further enhanced to meet the growing demand for efficient and environmentally friendly transportation in ports, injecting new vitality into the development of the global port transportation industry.
