Meet, the heart warm


Once again when the spring breeze over time of the lintel and heart is always with the footsteps of spring, roaming in the nature culturelle, breathe the fresh air, the brow and heart, just like is the awaken of spring is abundant, smell the scent of soil, the heart as if already was pale green, all things are lost in the spring tides occur, a little bit, a little bit, in imperceptible in, change the color of the season, at this time, my thoughts always with ink, in the spring tide of the ups and downs, sea through the window of time pavilion, through the cycle of the changes of the earth, drift in the depths of time. Stagnation in the season we met.

It was a late autumn, all covered with bleak and desolate, patches of fallen leaves in the autumn wind float away, the heart is full of sad melancholy, as if oneself is a lonely fallen leaves, in the glow of your sun quartermaster, wounds in the autumn cold wind, no marginal falling, piaoxiang distant without destination.

At that time, always likes to make the mind, on the tip of painted blue light line, between the residual constant DuanBi to pick up bits and pieces of memory, to piece together not perfect life.

In that sad lonely season, you appear in my words, culturelle see you every article reviews, in the heart of the moment. You understand and understanding, to set up a bridge of friendship between us, in a strange, we became bosom friend pity, and encourage each other friends.

Since then, in the sea on a boat, 'each other, all of my heart are printed on your smile, we hand in hand in the text, walk in the time, with words to each place of mind, to taste the leaves, deep to feel deep in the arid and desert, long time heart pulled close distance, in meet, forged a text.

And you meet, changed my boring day, in my world of silence added color and fragrance, is you give me support and encouragement, and I didn't have the confidence and courage, give the people to read the text display. Let the heart, with the words, came out of the world which was full of sad and melancholy.

Meet is boundless, need is deep love, earth buckish, we are all in light with vicissitudes of life, let the dribs and drabs feeling, into the spring breeze in comfort each other, miss string, use the mo shakes hanging branches, a number of years in the life the best memories, carved in the depths of the time, and write in that moment, the falling of a star will remember each other, and in the distance with a heart in prayer for you, for your blessing.

Sometimes in life, a turn round is the end of the world, sometimes, a common nature of the meet, is doomed to eternal of life. I like in the quiet, a window of the moon alone, with a quarter of the wind, in the text, to find your shadow, with the ink, the use life to embrace this friendship, even if, we in the distant, face still not familiar with electrical desk, but your memory is so precious.

With the spring breeze blow gently, my thoughts always flying over mountains, through the season and linger in memory, read on the tip of the finger lightsome, use that a string of letters to beautiful spring scenery, to warm, warm the heart. Warm insipid life. Let the process the same scenery, take a grateful heart, to walk in the world, in the bloomy spring season, let the memory to the depths of the bloom in the world of mortals.

High efficiency motor promotion

At present, many countries have attached great importance to energy-saving motor system. The United States, Europe, Canada, Australia and other countries and regions have established energy efficiency standards for motor. In 2008 October, the International Electrotechnical Commission ( IEC ) issued a IEC60034-30 " single speed, three-phase squirrel cage induction motor efficiency classification " standard, unified the motor efficiency standards around the world, will unify motor energy efficiency standards are divided into IE1, IE2, IE3, IE4 four grades. Among them, the standard IE1 efficiency, IE2 efficiency, IE3 for ultra high efficiency, IE4 is a higher efficiency levels teco dc motor speed control.

From 2012 September onwards, China began to implement the new national standard GB18613-2012 " small three phase asynchronous motor energy efficiency limit value and energy saving evaluation ", to stop the production of Y, Y2, Y3 series motor, mainly the production of motor based on IE2, IE3 efficiency rating. Is expected in the future, motor IE2 efficiency will be the use of 50W600 cold rolled non-oriented electrical steel, super efficient IE3 motor efficiency rating will be to use the 50W470, 50W400, 50W350 cold-rolled non-oriented electrical steel, motor is more efficient ( such as IE4) cold may use more high grade non-oriented electrical steel gear motor.

With the continuous development of our national economy, the future for a long period of time, the motor output will continue to increase. According to the international general method, the motor installed capacity of generators installed capacity of 2.5 times ~3.5 times. Accordingly, to 2020, our country motor installed capacity will reach 4500000000 kilowatts or so. Therefore, the popularization and application of high efficiency motor has a broad market space for development, will pull the non-oriented electrical steel for cold rolling demand 48 volt dc motor products.

In addition, with the development of home appliance, automotive, electrical and other industries, is expected to "1025 " end, China s demand for cold rolled non-oriented electrical steel will reach 6780000 tons ~740 tons brushless motor manufacturer.

Development of frequency conversion technology

How to use the existing technology to achieve the purpose of energy saving is the most effective, has been one of the national science and technology development direction, frequency conversion technology at this time will inevitably enter the country.

Every corner of VVVF technology we have in-depth life, control method of variable frequency speed system including V/F, vector control ( VC ), direct torque control ( DTC ). The V/F control is mainly used in performance at low cost, less demanding applications; and vector control are introduced, then started to the application of frequency control system in high performance applications. In recent years, with the development of semiconductor technology and the popularization of digital control, application of vector control has been extended from high performance field to the universal driving and driving situations, and the inverter air conditioner, refrigerator, washing machine and other household appliances. AC drive has been published in industrial robots, automation equipment, is widely used in machining tool, transmission equipment, elevator, compressor, steel rolling, pumps, electric car, lifting equipment and other fields. With the rapid development of semiconductor technology, MCU processing ability of more powerful, processing speed upgrade, variable frequency speed regulation system has the capacity to handle complex tasks, the realization of complex observation, control algorithm, the transmission performance and therefore to hitherto unknown height. And now the variable frequency drive PWM using synthetic drive mode, which requires the controller has strong ability of PWM generation.

Energy demand was greatly affects the development of the global economy. China is also facing various 24 volt dc motor the pressure of economic growth on energy demand. The energy consumption of the ninety's high energy-consuming products is higher than in developed countries 12-55%, energy utilization efficiency is only 32%.

China is in urgent need to improve the efficiency of energy utilization. The motor is one of the major energy consumption. China's motor installed capacity reached 400000000 kilowatts, the annual power consumption of 600000000000 kwh, accounting for 80% of industrial power consumption, but until now, China's various types of motors in use 80% or more of the asynchronous motors, tecoelectric.com visible in China has great potential in the field of motor energy saving. Energy saving technology of motor is the most notable variable frequency speed control technology. However, research on the inverter technology of China although is very active, but industrialization still is not ideal, 24 Volt DC Motors Catagory foreign products accounted for almost the VVVF technology market 60%.
