Smarter, More Reliable & Efficient VFD Solutions for Global Industry
Dedicated to independent R&D & manufacturing of frequency converters
Shenzhen Xintaigong Technology Co., Ltd. (brand: TAGOL) is an integrated manufacturer specializing in the R&D and production of variable frequency drives. As an innovation-driven high-tech enterprise founded in 2008, we have accumulated nearly 20 years of expertise in frequency conversion technology and participated in the formulation of industry standards in China.
Our product portfolio covers General Purpose VFD, Single-Phase VFD and Solar Pump Inverter, catering to diverse application scenarios across machinery, water pumping, renewable energy, HVAC and other industries. Back in 2008, we pioneered the new generation VFD adopting current vector control and IGBT modules, delivering high-precision control over motor torque and speed. Our products stand out for outstanding dynamic response, strong low-frequency torque output and superior energy efficiency.
To date, more than one million TAGOL branded drives have been deployed globally. Supported by advanced testing infrastructure and rigorous quality control workflows, every unit undergoes full performance testing and reliability validation. Our inverters feature stable operation, simple installation and user-friendly operation, together with responsive, reliable after-sales support.
Through continuous product iteration and solid technical capabilities, we have gained wide recognition and trust from customers at home and abroad, with our brand influence steadily expanding.

TAGOL Development History

Founder & Chief Engineer
With over 20 years of deep expertise in the frequency inverter industry, Qiu Yanhua is the technical core and driving force behind XintaiGong Technology Co., Ltd.
In 2008, he founded the TAGOL brand and led his team in the independent R&D of TAGOL's very first frequency inverter — the AS2 series. He spearheaded the development of key technologies such as sensorless vector control algorithms and high-torque low-frequency starting technology for the AS2 series, and holds over 20 patents related to frequency inverter topologies and technical solutions.
Dissatisfied with the "high failure rates and difficult after-sales service" of conventional frequency inverters under harsh operating conditions, he established XintaiGong Technology Co., Ltd. with a remarkably pure original aspiration: to create frequency inverters that can "tough it out" in extreme environments and are as easy to maintain as a switch.
Today, under his leadership, the R&D team has launched the AS2, TG500, and TG600 series products, which are widely used in mining, HVAC, solar energy, and oil drilling applications across Southeast Asia, Europe, and South America. To this day, he still personally oversees the destructive testing of every prototype and adheres to a steadfast rule: "No product leaves the factory without passing a 48-hour full-load burn-in test."

FAQ
2. Check whether the wiring is wrong or short-circuit leakage.
2. The setting of the motor or the motor connection is aging and foreign objects are stuck.
3. The motor itself is broken and can't be started.
High-temperature and dust-resistant frequency converters should be used in tropical areas such as Africa.
Russia and other cold regions should choose frequency converters with high low temperature resistance.
Annual inspection: Engineers use infrared thermal imaging and ESR table to check the capacitance status and issue equipment health reports.
Predictive maintenance: optional Internet of Things module, real-time monitoring of operating data, prediction of potential faults (such as fan speed decline, capacitance value attenuation), and early warning 3 months in advance
