Advantages of neodymium iron boron motors in ship applications

Related technical research has shown that the use of neodymium iron boron magnetic materials simplifies the structure of the motor, improves reliability, and eliminates rotor copper loss, thereby improving the efficiency of the motor.

Due to the use of permanent magnet material poles, the magnetic energy product is high, resulting in a higher air gap magnetic flux density. Therefore, motors with the same capacity have a smaller volume and lighter weight; The rotor has no copper and iron losses, and there is no friction loss between the collector ring and the brush. It operates efficiently and the air gap magnetic field is mainly or entirely provided by the rotor magnetic field, with high power density and high power factor; Small moment of inertia, allowing for large pulse torque, achieving high acceleration, and good dynamic performance; Simple and compact structure, reliable operation, convenient maintenance, and long service life.

According to research data from a certain institution, the electric ship market, including both water and underwater, will rapidly grow from $2.6 billion (approximately RMB 16.14 billion) in 2013 to $7.3 billion (approximately RMB 45.31 billion) in 2024. As high-power pure electric ships become increasingly feasible, the market capacity of electric outboard engines will increase to three times.

The forefront of the industry believes that CRRC is a leading enterprise representing China's manufacturing strength. CRRC Zhuzhou Electric Motor Company's permanent magnet synchronous traction motor system has successfully entered the field of electric ships, which not only represents the company's business progress, but also represents the progress and development of the industry. It can also be considered that the development of the electric ship industry has reached a new level, which also means that neodymium iron boron enterprises have ushered in new reform dividends.
