315: Those product slots in the motor industry have you ever encountered?

Every year on March 15th, China celebrates its Consumer Rights Day, and the annual 3.15 event has become a major highlight of the day. This day is not only about raising awareness of consumer rights but also serves as a platform for exposing various business violations and unfair practices. In recent years, the CCTV 3.15 program has revealed that with the rapid development of the Internet industry, it has increasingly become a hotbed for consumer complaints. Issues such as deceptive marketing, hidden fees, and misleading information have affected platforms like Taobao, car-sharing services, and online encyclopedias. Many businesses have been exposed and criticized for their unethical practices. While the tech sector faces these challenges, traditional industries like the motor manufacturing sector are also plagued by problems. Let’s take a closer look at some of the issues in this industry. **Selling Fake Motors Led to Legal Action** Lee ran a motor sales business, while Hwang operated an electric tricycle shop. The two had worked together since 2010, and Hwang trusted Lee's reputation. He often ordered dozens of motors, which were consistently of good quality. However, things took a turn in January 2012 when Lee sent another batch of motors to Hwang. Hwang, trusting his long-term partner, didn’t inspect the package on the spot and paid 18,000 RMB immediately. Later, he noticed some strange behavior — sand was leaking from one of the boxes. When he opened it, he was shocked: the motor casing was old and had been repainted. Inside, instead of copper wires, there were stones and dirt. After checking all the motors, he found them all to be fakes. He then decided to take legal action against Lee. **OEM Motors: A Hidden Risk** With the growing demand for electrical machinery, many small workshops have emerged. Due to the difficulty in identifying technical specifications, these small manufacturers often produce low-quality motors and affix well-known brand labels to them, creating what is known as "OEM" (Original Equipment Manufacturer). These products are not reliable and often lack the quality of genuine branded motors. Consumers are advised to purchase directly from authorized dealers or original manufacturers to avoid being deceived. **Low Efficiency and Potential Problems** Overall, the operation of high-efficiency motors in China is still slow. International standards include more than just three levels of energy efficiency, such as IE4 and IE5. IE4 uses permanent magnet technology, which is more efficient. China, as the world's largest exporter of rare earth materials, has a natural advantage in this area. However, most of the rare earths are exported rather than used for research and development. There are still many issues and areas for improvement in the motor market. Experts suggest that manufacturers should focus on several key areas. First, they should pay attention to the use of frequency converters, as companies like ABB and Siemens already integrate them with motors. This allows appliances to use less power when not under load, reducing stress on the motor. Secondly, over 50% to 60% of motors currently on the market are still IE1, which can lead to inefficiencies. Many motors are oversized for the actual load, resulting in wasted energy. Thirdly, there is a need to consider how motors perform under no-load conditions. Finally, improving the transmission system, such as conveyor belts, can significantly reduce energy loss. In some cases, better conveyors can save up to 10% in costs. By addressing these issues, the motor industry can move towards greater efficiency and sustainability.
