China develops permanent magnet motor for 400 kph high-speed train

developer said Tuesday.

The newly-developed TQ-800 motor is expected to be used in a multinational interconnected high-speed train project, according to the CRRC Zhuzhou Electric Co., Ltd.

Adopting a fully-enclosed and directional cooling structure, the TQ-800 motor boasts high power density, excellent low-temperature adaptability and low maintenance cost, the company said.

The successful development of the motor breaks the monopoly of foreign technologies in this area and lays a solid foundation for the upgrade of rail transit technologies in China, it added.

The maximum speed of China’s bullet trains rose to 350 kph when the Fuxing (Rejuvenation) bullet trains started operation between Beijing and Shanghai on Sept. 21, 2017.

The Fuxing trains are a substantial upgrade on the previous Hexie (Harmony) bullet trains. Entirely designed and manufactured in China, the Fuxing train is more spacious and energy-efficient, with longer service life and better reliability.

Intelligent robot workstations, intelligent work islands, providing the entire process (cutting, assembly, welding, grinding, inspection, etc.) of intelligent applications for the non-standard metal structure manufacturing industry.

Fans and friends brought components from their factory to our company for inspection and trial welding.

No programming was required.

We could choose any one and place it on our welding workbench.

We only accelerated the unedited content of the following test.

We can see the impact of robot vision on this component.

It scanned the welding seams of the outer and inner circles and uploaded the program to the robot.

Then the welding started.

From moving into position to starting the arc, it took about one minute.

The robot continuously welded all the seams on the outer and inner circles.

This is the welded result.

Later, the customer requested to test multi-layer and multi-pass welding.

Compare this welding process with the 600 welders in your factory who work every day.

Facing the diversified construction conditions of the power tower industry, our intelligent robotic welding system delivers stable, beautiful weld seams while redefining the production process.

Simply place the components — no model import required.

With advanced visual imaging and reverse modeling, the system automatically performs path planning for fully automated welding. Robots operate autonomously along the ground track, completing the entire process from the first weld to the last without human intervention.

After finishing one side, the system automatically turns the component and continues welding on the other side.

One operator can manage multiple intelligent welding lines at the same time.

This solution significantly reduces reliance on highly skilled welders, transforming production efficiency and product quality from difficult-to-control variables into predictable, stable, and manageable outputs.
