In response to the global trend of energy conservation and carbon reduction, Formosa Plastics Group has continued to target new energy, automotive composite materials, biotechnology and medical exploration, and oil and gas exploration in recent years, and gradually develop and develop to strengthen the Group's multi-profit upgrade advantages.
Among them, the new energy business develops the next-generation new blue ocean with existing LEDs, such as UV LEDs; secondly, it develops lithium-iron start-up batteries with solar photovoltaic integrated system batteries and wind power.
Formosa Plastics Group believes that although the current acceptance of LED lighting has increased, it is not yet a "sweet spot" for consumers. South Asia Optoelectronics will first seek profit-making mode to enrich its competitiveness. South Asia Optoelectronics is a joint venture between Jingdian and Nanya Plastics. Jingdian is responsible for upstream epitaxial wafer and wafer development, and South Asia is responsible for downstream lighting sales.
At the end of 2012, Nanya Optoelectronics announced that the LED bulb automatic production line has been completed, leading the global LED bulbs into full-automatic production; in addition to strengthening the production cost competitiveness of the LED industry, it also throws out cooperative development for international manufacturers to replace competition. The concept is to adopt a dual-track system of brand and OEM to develop overseas sales opportunities.
After South Asia Optoelectronics started the fully automated production line, the mass production scale is estimated to reach 400,000 to 500,000 LED bulbs per month at full load. In the future, LED lamps will be fully automated, and the most suitable amount of Formosa Plastics Group will be further developed. Produce manufacturing power and develop LED lighting layout.
In addition, Formosa Plastics launched the "Taiwan-plastic lithium-iron smart starter battery", becoming the first Asian company to pass the international-level safety certification battery, aiming at the alternative business opportunities of European lead-acid batteries. The cement factory for Ningbo's lithium battery for the joint venture between Formosa Plastics and Mitsui Chemicals Co., Ltd. is scheduled to be completed and put into production in 2016, and domestic demand business opportunities will benefit.
The development of direct-drive servo motors for steering wheels was mainly targeted at precision agricultural machinery. It can complete agricultural machinery operations, achieve precise positioning, improve agricultural productivity, effectively use agricultural resources, and protect the ecological environment. This is an effective way to achieve high-quality, high-yield, low-consumption, and sustainable environmentally-friendly agriculture. It can achieve fast, efficient, high-precision and automated operations on large areas of arable land. It is mainly used in multiple production links of land production, pesticide sowing, harvesting and spraying, which greatly improves production efficiency and land use.
Motor design characteristics:
adopts direct drive motor design
Waterproof and dustproof design
Integrated design of motor and servo control
Easy and fast installation
The rotor is directly coupled to the load shaft
Control performance characteristics:
AC Servo Solution Design
SVPWM vector control, fast system dynamic response
Dedicated encoder, high control accuracy and good stability
With speed control mode and position control mode
Extremely high running accuracy:
This machine adopts sine wave, vector control and high-precision magnetic encoder, with high control precision, which can ensure that the vehicle can walk within the error range of ± 2cm.
Good control line performance:
The torque of the direct drive servo motor increases in proportion to the input current and does not change with speed and angular position. The relationship between torque and current is linear. Multi-pole structure design, low motor torque ripple coefficient, stable operation, can effectively reduce the "S" curve amplitude when the vehicle is going straight
Powerful acceleration and deceleration capabilities:
The direct drive design of the servo motor enables gearless transmission. The ratio of torque to inertia on the load shaft is much better than gear transmission, which greatly improves the acceleration capability of the system, and greatly improves the ability to go online quickly in applications and the ability to correct errors under high-speed vehicle operation
Not easily deformed
The direct drive motor is mounted directly on the load shaft. No gear gap, no elastic deformation, high transmission efficiency, good rigidity, etc., suitable for steering wheel control characteristics. While ensuring high torque, it is also convenient for human emergency operation
Faster response time
The mechanical constant and electrical time constant of the direct drive servo motor are small, which ensures fast response in applications under a wide range of operating speeds, greatly improving the sensitivity of the system and improving the straight line of operation.
