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 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.

1) FSDrive-MX1 series frequency converter:
The FSDrive-MX1 frequency converter series is developed based on multi-level series-connected matrix converter technology. With this new pioneering technology from Yaskawa, Yaskawa has produced a medium-voltage matrix converter capable of regenerating energy without generating harmonic distortion on the power supply or voltage spikes on the motor, while offering high-precision control.
The FSDrive – MX1 series matrix converter uses matrix conversion technology that overcomes the common problems found in conventional frequency converters. The FSDrive – MX1 series enables powerful energy savings through its regenerative function and optimal control of medium-voltage motors thanks to its sinusoidal input supply and output signal.
Industrial applications: Lifts, cranes, conveyors, HVAC, industrial pumps and fans, mining, ...
Power range:
3kV, 200kVA to 3000kVA
4kV, 550HP to 4000HP
6kV, 400kVA to 6000kV0041

2) FSDrive-MV1000 frequency converter:
MV1000 applies smart harmonic technology and a three-level voltage control method to optimize input harmonics and output waveform, so it can be used not only for constant load applications but also for variable load applications such as pumps and fans
FSDrive-MV1000 medium-voltage frequency converter with outstanding features:
- Compact design, reduced size with power cells that are easy to install and remove, facilitating transportation, installation, and maintenance.
- Inherits a high-performance controller, outstanding functions, and the reliability of the low-voltage frequency converter series, helping the system operate stably and continuously.
