The Internet of Things and Photovoltaic Industry were included in the first batch of emerging industrial bases in Guangdong

The first batch of awarding ceremony for strategic emerging industrial bases in Guangdong Province was held in Foshan. The Dongguan IOT industry base and thin film solar photovoltaic industrial base in our city were identified as “the first batch of strategic emerging industrial bases in Guangdong Province ” .

" Apply " card to help the Internet of Things

It is reported that the Dongguan Internet of Things can be selected in the siege of advanced technology cities such as Shenzhen and Guangzhou, emphasizing that " application " is a major feature of Dongguan Internet of Things.

According to Yang Shugang, general manager of the business department of Dongguan Yishili Technology Co., Ltd., although Dongguan has accumulated certain technological advantages in the technology level of the Internet of Things, it was short-listed as the “ first batch ” of strategic emerging industrial bases and played out “ characteristics ”. The card has a lot of points for Dongguan.

Yang Shugang introduced, “ Especially in the Humen Port Industrial Park, processing trade, foreign trade companies and large-scale logistics circulation enterprises have gathered. The application of the Internet of Things in Dongguan has obvious advantages over other places. We believe that if the Internet of Things does not emphasize the use of this year, When we talk about technology, we may still talk about technology after five years. There is no market demand and application support, and the Internet of Things is always in the concept of speculation. "

It is reported that the provincial government will spend 2 billion yuan every year for 5 consecutive years to support the " strategic emerging industries. " As far as obtaining the licensing of the Internet of Things (IoT) base, Dongguan can obtain many preferential policies and support funds. At present, there is no specific data.

Photovoltaic core park total investment 13 billion

According to the introduction of the City Economic and Credit Bureau, Dongguan Thin-Film Solar Photovoltaic Industrial Base is based on the existing leading enterprises in the thin-film solar photovoltaic industry, and the overall planning and construction of the province-city joint construction base.

The base will focus on the construction of three photovoltaic solar energy industrial parks, including Qishi Thin Film Solar Photovoltaic Industrial Park, Humen Port Lingang Industrial Zone Solar Cell Processing and Exporting Industrial Park, and Nancheng Thin Film Solar Energy Equipment Industrial Park. At the end of the “ Twelfth Five-Year Plan ” period, the base plans to build 2 or 3 leading silicon-based thin-film solar cell manufacturing enterprises with an output value of over 10 billion yuan. The total investment in the core campus is 13 billion yuan.

Fan Jiliang, executive chairman and chief executive of Dongguan Hongwei Technology Co., Ltd., which is located in the upper reaches of the solar photovoltaic industry chain, had disclosed to reporters that it would invest 12 billion yuan in the production of solar photovoltaic thin film batteries in Dongguan.
But as the provincial strategic and emerging industrial base, the solar photovoltaic industry in Dongguan provincial level can be assigned to a specific number of support policies and funding "beauty soup", it has not yet been clarified.

However, it is certain that the “Provisional Measures for the Administration of Financial Assistance Funds for Golden Sun Demonstration Project” issued by the government clearly states that “ Grid-connected photovoltaic power generation projects shall, in principle, account for 50% of the total investment in photovoltaic power generation systems and their associated transmission and distribution projects . Give subsidies, and independent photovoltaic power generation systems in remote and non-electric regions provide subsidies at 70% of total investment. ” Yang Jinghe

LED or finalist " second batch "

The detailed list found that the LED industry that has been doing well in Dongguan has not been " admitted to the first batch " . According to industry analysts, the LED project in Dongguan failed to be “ admitted ” this time, probably due to “ the problem of balancing the cities in the province ” .

As a representative member of LED industry chain in Dongguan, FAN Ningning, Deputy General Manager of Dongguan Fudi Electronic Material Co., Ltd. analyzed: “ Compared to the first batch of Foshan and Jiangmen that were on-line, Dongguan’s LED industry chain is not yet perfect. However, relevant aspects are Efforts are being made to improve and it is estimated that they will be short-listed for the ' second batch ' . "

It is reported that this time selected industrial bases have been signed by the provincial economic and information committees and the people’s governments of the industrial bases to sign a joint construction agreement, implementing dynamic management and conducting assessments every two years. The qualified industrial bases shall be confirmed, and unqualified revoked titles shall be announced and delisted.


Advantages of Permanent Magnet DC Motor or PMDC Motor

PMDC motor have some advantages over other types of DC motors. They are :
    1. No need of field excitation arrangement.
    2. No input power in consumed for excitation which improve efficiency of DC motor.
    3. No field coil hence space for field coil is saved which reduces the overall size of the motor.
    4. Cheaper and economical for fractional kW rated applications.

Disadvantages of Permanent Magnet DC Motor or PMDC Motor

    1. In this case, the armature reaction of DC motor cannot be compensated hence the magnetic strength of the field may get weak due to demagnetizing effect armature reaction.
    2. There is also a chance of getting the poles permanently demagnetized (partial) due to excessive armature current during starting, reversal and overloading condition of the motor.
    3. Another major disadvantage of PMDC motor is that, the field in the air gap is fixed and limited and it cannot be controlled externally. Therefore, very efficient speed control of DC motor in this type of motor is difficult.
Dc Spur Gear Motor including a dc motor and a spur gearbox.


A spur gearbox could be either square type or round type as following:

square dc spur gear motor
round dc spur gear motor

According to the size of the gearbox, normally we have 12mm DC Spur Gear Motor, 25mm DC Spur Gear Motor, and 37mm DC Spur Gear Motor and so on.
12mm dc spur gear motor
25mm dc spur gear motor37mm dc spur gear motor
DC Spur Gear Motor are relative simple in production, so the output efficiency is limited. According to the stages of the gear trains, the efficiency reduce one by one. However, the price would be a bit cheaper than other types DC Gear Motor .
