On March 15, 2008, the Suzhou Bureau of Science and Technology hosted an appraisal meeting for the "Encoderless Permanent Magnet Synchronous Motor Inverter" developed by Kunshan Youni Kang Industrial Technology Co., Ltd. The event was chaired by Professor Chen Boshi, a leading expert in the inverter industry in China. Representatives from prestigious institutions such as Tsinghua University, Zhejiang University, Shanghai University, Suzhou University, Alstom of France, and Shanghai Electric Group attended the meeting. They highly commended the technological achievements, noting that the inverter’s capabilities in parameter identification, self-tuning, speed and position estimation, and software design have reached both domestic leading and international advanced levels. This breakthrough is expected to significantly expand the application of permanent magnet synchronous motors in industrial drive systems, and the appraisal was unanimously passed.
Permanent magnet synchronous motors are known for their energy efficiency, compact size, lightweight design, high overload capacity, stable speed under varying loads, and overall reliability. These features make them an ideal choice for high-power variable frequency drive systems. However, their widespread use has been limited due to challenges in starting and control. The development of an encoderless inverter for these motors marks a major advancement, offering substantial economic benefits. Despite the complexity involved in integrating multiple technologies, no mature industrial product had been available on the market until now. Kunshan Youni Kang has taken the lead in this field, creating a specialized inverter that greatly enhances the versatility of permanent magnet synchronous motors, allowing them to perform reliably in harsh environments like oil fields, coal mines, and large construction equipment.
In addition, Unicon will be participating in the 12th International Industrial Automation Conference, which will take place at the Shanghai Everbright Convention & Exhibition Center from June 4th to 6th. This event presents a valuable opportunity for the company to showcase its latest innovations and connect with industry professionals from around the world.
