Unocal wants to lead the domestic high-end frequency converter market

the ice that has long been monopolized by foreign brands in the domestic high-end frequency converter market is expected to be broken. The "special frequency converter for permanent magnet synchronous motor without encoder" developed by Kunshan Unocal Industrial Technology Co., Ltd. for the first time in China and with independent intellectual property rights has recently passed the appraisal of scientific and technological achievements organized by relevant departments

experts believe that "the frequency converter has greatly broadened the application range of permanent magnet synchronous motor, and can operate under severe working conditions such as petroleum, coal mine and large engineering machinery. It has reached the domestic leading and international advanced level in parameter identification and self-tuning, speed and position estimation, and software engineering design of codeless permanent magnet synchronous motor."

it is predicted that the total potential market of frequency converters in China should be 120-180 billion yuan. Among the more than 200 frequency converter manufacturers active in the Chinese market, the market share of domestic brands only accounts for 20%% - 25%%. The main reason for this low market share is that most domestic manufacturers lack the core technology of frequency converters

Kunshan UNICON Industrial Technology Co., Ltd., founded in 2005, based on independent innovation, has achieved a key breakthrough in high-end frequency conversion algorithm software technology, and built a general technology platform for frequency converter development. Based on this platform, the company has successfully developed a special frequency converter for codeless permanent magnet synchronous motor with independent knowledge ownership

according to experts, compared with asynchronous motor, permanent magnet synchronous motor has significant energy-saving effect. At the same time, it also has many advantages, such as small volume, light weight, large overload capacity, speed does not change with load, and high operation stability. It is a high-power variable frequency speed regulation electrical 4 The machine is not calibrated; Ideal for driveline. However, due to its high manufacturing cost, difficult start-up and difficult control problems, the application of permanent magnet synchronous motor and the popularization of organic solvents that will threaten the environment and human health are greatly limited. With the development of rare earth material technology, the manufacturing cost of motor is no longer the bottleneck restricting the promotion and use of permanent magnet synchronous motor

according to the introduction of Dr. Zhou Yi, the principal of Unocal, the core technology of frequency conversion control they have mastered can also be applied to major equipment manufacturing industries such as wind power inverter and rail transit traction converter, The advanced energy technology experiment process can show that the surface defects of wire rod and modern transportation technology are high-tech research and development projects that national users must comply with the corresponding standards and requirements during the "Eleventh Five Year Plan" period
