Contact

Short Description

Yaskawa Electric was founded in 1915 and is a world-leading group in the manufacturing and supply of products in the fields of frequency converters, electric drives, and industrial robots worldwide, headquartered in Kitakyushu, Japan. Yaskawa's products combine research achievements in mechanics and electronics into a single product. Yaskawa was the first company to introduce the now-famous concept of “Mechatronics,” which has since become a key field attracting a great deal of attention, as mechatronics enables the creation of products that meet the ever-increasing demands of production and daily life.

 

PART I: GENERAL INTRODUCTION TO YASKAWA FREQUENCY CONVERTERS

 

In the field of frequency converters, Yaskawa is currently the world's leading frequency converter manufacturer, with production facilities across the globe: Japan, the USA, the UK, China, etc. As of 2014, Yaskawa had supplied more than 20 million frequency converter products of various types to the market and become the manufacturer with the largest number of frequency converters distributed worldwide to date. Over the years, Yaskawa has consistently ranked among the world's top frequency converter suppliers. Yaskawa is proud to have served as an OEM for many famous companies such as: Sumitomo Heavy Industries, Mitsubishi Heavy Industries, Hitachi Zosen, Kawasaki Heavy Industries, Mitsui Zosen, Omron, Keyence, Yokogawa...

These achievements are due to Yaskawa always being a pioneer in new initiatives and technologies for frequency converters, continuously creating new frequency converter products with higher quality and reliability, more new and smarter features, … contributing to the modernization of industries such as mining, cranes, packaging, cement, paper, oil and gas, beverages, and machinery manufacturing …..

Yaskawa's frequency converter products have won many different awards, such as: the Deming Prize, the V1000 Award for Most Innovative Product, the Ohm Technology Award, the Frost & Sullivan Excellence in Technology Award 2004, Control Engineering magazine's Customer Satisfaction Award, and the World's No. 1 Frequency Converter Supplier award for two consecutive times (2004 and 2006), presented by the prestigious Control Engineering magazine.

Yaskawa is not only the world leader in quantity but also leads in quality and very high reliability. Yaskawa's frequency converter products have an MTBF far exceeding common industry standards (approximately 22 years, equivalent to 200,000 hours) (MTBF – Mean Time Between Failures: a reliability index reflecting product quality over time, representing the product's ability to maintain function during a specified period). Yaskawa has been ranked among the top 5 companies with the best product quality by the renowned “Quality Magazine”. Even more proudly, Yaskawa is currently the only industrial product manufacturer to receive the “Deming Prize for Quality”, the most prestigious quality award in manufacturing.

 

PART II: YASKAWA MEDIUM VOLTAGE FREQUENCY CONVERTERS

Building on its foundation of experience and superior technology in low-voltage (LV) frequency converters, electric drives, power electronics, mechatronics, and semiconductor devices, Yaskawa has developed and become one of the leading and pioneering manufacturers in supplying medium-voltage (MV) frequency converters.

Yaskawa đã phát triển và trở thành một trong các nhà sản xuất hàng đầu và tiên phong trong cung cấp các loại biến tần trung thế MV

Yaskawa launched its first medium-voltage frequency converter product line in the Japanese market in 1996. After 18 years of continuous development and improvement of control methods, Yaskawa's medium-voltage frequency converters have been increasingly appreciated by customers for their reliability, performance, and quality. Yaskawa's frequency converter products are well known for their compact size, user-friendliness, integrated smart PLC function, excellent energy-saving capability, fast acceleration and deceleration, and the ability to allow long cable distances from the MV drive to the load…

Yaskawa was the first company to introduce the famous PWM-controlled medium-voltage (MV) frequency converter, capable of running many different types of equipment. Yaskawa was also the first manufacturer in the world to introduce and commercialize a medium-voltage frequency converter using Matrix Converter technology.

Many famous projects in Japan and around the world trust and use Yaskawa's medium-voltage frequency converters, such as: NIPPON STEEL & SUMITOMO METAL DITTO KIMITSU PLANT, OSAKA CITY AMAKUBO LIFTING PUMP PLANT, POSCO, EBARA REFRIGERATION EQUIPMENT & SYSTEMS, YASKAWA-SIEMENS JSC, TOKYO ENERGY&SYSTEMS, MITSUBISHI MATERIALS DITTO KYUSHU PLANT, SAMSUNG FINE CHEMICAL, SUMITOMO RUBBER INDUSTRIES, MITSUBISHI PAPER MILLS ENGINEERING HACHINOSE PLANT, GE OIL & GAS-PACIFIC, …

Yaskawa's medium-voltage frequency converters are used in a wide range of applications such as: mining, water supply and wastewater treatment, power generation, rubber and tire manufacturing, oil and gas, cement, and large-capacity pumps and fans. One typical example demonstrating the success of Yaskawa's medium-voltage frequency converters is that Yaskawa now holds nearly 100% of the market share for frequency converters used in "blast furnaces" operating 24/7 in Japan stably and reliably.

Yaskawa currently offers various medium-voltage frequency converters on the market to serve different applications and requirements, such as:

– In 2005, Yaskawa introduced the FSDrive-MV1 series, a matrix converter with energy regeneration capability, including the FSDrive-MV1S frequency converter for energy-saving control and the FSDrive-MV1H frequency converter for high-performance control. This product line is applied in steel, paper, and cement plants… for applications requiring energy regeneration

– In 2011, the FSDrive-MV1000 series of frequency converters was introduced, considered the world's most compact medium-voltage frequency converter series, used for constant-torque and variable-torque applications such as pumps and fans.
