Huang Xianxiong, chairman and general manager of Shenghua, confirmed on the 14th that Shenghua will be able to streamline operations, and three factories including Suzhou Union, Dongguan Wanshida and Dongguan Songshan Lake have been completely shut down and launched large-scale dismissal operations; Large-scale layoffs will also be made, and only the Tanzi factory will be left in the future.
After the reorganization of the financial crisis, Shenghua started the compact project in September, and successively shut down a TFT-LCD factory in Taoyuan Yangmei, and the Taichung factory, and began mass layoffs.
Shenghua will dismiss 2,360 employees in Taiwan in batches starting this Wednesday. The company's internal rough estimate, as of the end of this month, Taiwan's factory area will automatically resign, the number of layoffs will reach 4,300, leaving only about 300 people in the future, only about 6% of the manpower. Huang Xianxiong is not willing to talk more. It is reported that Shenghua will completely withdraw from the manufacture of touch panels and transform new businesses such as biotech food and LED lighting.
A single-phase VFD, also known as a variable frequency drive, is a specialized electronic device used for precise control and regulation of single-phase motors. Unlike three-phase motors that are commonly used in industrial applications, single-phase motors are predominantly found in residential and small-scale applications.
The primary function of a single-phase VFD is to control the frequency and voltage supplied to the single-phase motor, thereby enabling accurate regulation of motor speed. By adjusting the frequency and voltage output, the VFD allows for smooth and precise control over the motor's rotational speed. This feature is particularly useful in applications where speed control is required, such as in residential HVAC systems, small-scale machinery, and household appliances.
Energy efficiency is a significant advantage offered by single-phase VFDs. By adjusting the motor speed to match the load requirements, the VFD reduces energy wastage and improves overall energy efficiency. When the motor operates at a lower speed during periods of low demand, energy consumption is significantly reduced, resulting in energy savings and lower operating costs.
Motor protection is another important aspect addressed by single-phase VFDs. They incorporate various protective features, including overload protection, short circuit detection, and thermal protection, which help safeguard the motor against damage due to excessive current, voltage fluctuations, or overheating. This ensures reliable motor operation, prolongs the motor's lifespan, and reduces the risk of unexpected failures.
Harmonic filtering is also a critical consideration in single-phase VFD applications. When single-phase VFDs operate, they can introduce harmonics into the power supply, which may cause issues such as voltage distortions and interference with other electrical equipment. To mitigate these problems, single-phase VFDs often incorporate harmonic filtering techniques to suppress harmonics and ensure a clean and stable power supply, maintaining power quality and preventing damage to connected equipment.
Control algorithms play a significant role in single-phase VFD operation. These algorithms allow for precise control and adjustment of motor speed, ensuring smooth acceleration, deceleration, and accurate speed regulation. Advanced control algorithms enable efficient motor operation and enhance overall system performance.
In summary, single-phase VFDs provide precise control and regulation of single-phase motors in residential and small-scale applications. With their energy efficiency, motor protection features, harmonic filtering capabilities, and advanced control algorithms, single-phase VFDs enhance motor performance, reduce energy consumption, and ensure reliable operation in various residential and small-scale applications.
