Inverter market competition, can be described as more intense, whether it is inverter manufacturers or users, which are facing an adaptation process. For manufacturers, the fierce competition means that their own inverter products must have the advantages of differentiation; And for users, the fierce competition allows more and more choices of inverter products in the purchase, The factors for reference have also become "chaotic flowers fascinating eyes."
In recent years, the requirements for the inverter in the industry are higher, and more detailed at the same time. Inverter is a kind of large-scale products, covering a very wide range of industries, and also need the occasion of the inverter, different industries have shown the characteristics are very different, only the choice of the real inverter for the industry, cost-effective In order to get a good reflection. At present, with the development of various industries, the requirements for the corresponding mechanical equipment are promoted very fast, which has a conductive effect on the performance and the functional requirements of the frequency converter.
User awareness of the inverter product increases, but also exacerbated the intensity of the competition. As frequency inverters are used more and more widely, users are getting more and more familiar with this kind of products. Before, most users are nothing less than only from the price, brand image and corporate marketing highlights several aspects to choose inverter products; and now, more and more users are starting from their own specific needs, the various manufacturers Product performance and focus on its features to make a more targeted comparison, the cost is more careful consideration, and even many downstream customers OEM users have begun to specify the use of some of the inverter brand. This forced the drive manufacturers to truly provide differentiated products, with unique product features to attract users.
In fact, in terms of technology, especially the core control technology, the development of inverters has been relatively mature, and the breakthrough points that can be sought are not many, so that manufacturers naturally start to find ideas in product design concepts. Now we can see that for the characteristics of the industry and users, most manufacturers embarked on two different routes, one is the development of generic products, the other is the development of special-purpose products.
So, the two different directions of the inverter, which one is better? Different manufacturers have published their own views on this.
Delta Electronics Co., Ltd. is undoubtedly the development of specialized products on behalf of manufacturers. Its original emphasis on product penetration of the industry, its inverter products also inherit the depth of the industry's "character", many of which are specially developed for a specific inverter products industry, the development of special inverter concept can be described Very clear.
The advantages of special-purpose products are mainly reflected in two aspects: on the one hand, special-purpose products are tailored to the needs of the industry, the industry will focus on the characteristics of the targeted set, is indeed more suitable for the needs of the industry. Although the core control method, which is not fundamentally different from the ordinary inverter, but in the structural design and function settings will have a greater difference, or integrate some of the functions needed by the industry.
On the other hand, he believes that the use of special-purpose products also have an advantage in terms of cost. Although the price of special-purpose inverter is slightly higher than that of ordinary inverter, users who use inverter, such as industrial machinery manufacturers, often need to consider not a one-time investment cost but a comprehensive and long-term cost and effect In addition, as this type of users, their own products also have a brand awareness, and machinery and equipment as an important part of the frequency converter, its reliability often affects the failure rate of the entire machinery. The special inverter industry-specific design to ensure its reliability is superior to ordinary inverter, reducing the downtime caused by a high failure rate caused by the loss in the long run is cost-saving.
For example, in the metal industry, Delta has a BW series frequency converter specifically for this part of the application. BW series inverters have special control functions for rewinding and rewinding, and do not need to rely on the PLC to be able to accomplish constant tension control, and have automatic coil diameter calculation and PID automatic adjustment function, and can independently control the unwinding operation in the system instead of direct current Speed. For port machinery and other crane load, Delta introduced the VE series inverter. The remarkable features of this series of inverters are: full vector control, configurable braking unit, four-quadrant operation and excellent dynamic response, In the full torque range, but also has a constant torque characteristics. In addition, Delta offers dedicated models and inverters for machines , plastics and textiles, and even custom-made products for some customers.
Also pay attention to the development of industrial inverter manufacturers and Hitachi, the launch of its dedicated to the elevator industry, machine tool industry inverter products has also become a show hot. Which specifically for the machine tool industry inverter, in addition to common features also integrates the position control function, making it more suitable for high-precision machining of the machine tool industry. The new SJ700 series inverter is ideal for start-up applications requiring low-speed instantaneous torque crane, elevator and other applications. The over-current suppression, over-voltage suppression function can greatly speed up the internal operation of the inverter speed and reduce the occurrence of tripping.
