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.

When selecting robotic welding systems and equipment, the real question isn't which one is objectively "best" – it's which solution fits your specific production scenario, team capabilities, and business goals. The right automatic welding robot for one manufacturer might be completely wrong for another, regardless of specifications or price.

Choosing a robotic welding system is not about finding the “best” machine on the market.

It is about finding the right solution for your real production needs.

Model import, reverse modeling, teach programming, drag teaching, 3D vision, seam tracking, AI welding — each method has its own advantages. The key is matching the technology with your workpieces, batch size, operator skills, and production workflow.

For batch production, model import and offline programming may be more efficient.
For small batches and frequently changing parts, reverse modeling and vision-guided systems can offer more flexibility.
For complex or confined welding areas, drag teaching may be more practical.

A good robotic welding system should not only weld well — it should also be stable, easy to operate, and suitable for the people who use it every day.

At JTC LASER, we believe the right welding automation solution should help manufacturers reduce labor pressure, improve welding consistency, and make production easier to manage.

Don’t just ask which robot is the most advanced.
Ask which one truly fits your factory.
