It is known by the 712nd institute of China shipbuilding industry corporation that the first set of permanent magnet propulsion electrical motor vehicle created by them is installed in a real boat. This means we make a great progress on the first set of permanent magnet propulsion electrical motor which is developed by ourselves and we hold completely independent intellectual property rights, which also takes an important step towards the application of real boats, demonstrating that technology of our ship propulsion reaches advanced level around the world.

It is acknowledged that permanent magnet propulsion electrical motor uses permanent magnet material and variable frequency speed control device to replace the excitation commutation and pressure adjustment of traditional motors. This makes permanent magnet propulsion electrical motor equipped with small volume, light weight, low noise, high efficiency, simple operation and maintenance to promote the performance of the ship. Permanent magnet propulsion electrical motor has become one of the landmarks of shipping technology, which is the main direction of the development of ship propulsion technology in the future as well.
