Efficient low-voltage VFD frequency converters and three-phase 380V vector frequency converters are the core equipment for energy-saving industrial motors. We recommend considering power, efficiency, control accuracy, and environmental adaptability when selecting.
Zhufeng Electric Co., Ltd. was established on 2004. It is a high-tech enterprise centered on the research and development, production, and energy-saving solutions of industrial automation equipment, with business covering areas such as frequency converters, servo drive systems, intelligent energy-saving equipment, and photovoltaic inverters. Our products are widely used in industrial scenarios such as machinery manufacturing, petrochemicals, metallurgy, building materials, and water supply.
By decoupling motor flux and torque, high-precision speed/torque control (± 0.01% accuracy) is achieved, especially suitable for low-speed and high torque scenarios (such as cranes and extruders). For example, the Bedford B503PRO series supports a power range of 0.75-630kW, with an adjustable output voltage of 0-380V, and is suitable for three-phase asynchronous motors.
The input voltage range is usually three-phase 380V ± 15% (323-437V), supporting a wide voltage fluctuation environment. Some models, such as the Powtech PT200 series, use IGBT power modules with an efficiency of over 98%, saving 15% -20% energy compared to traditional frequency converters.
Taking the centrifugal pump driven by a 110kW frequency converter as an example:
The power factor of traditional motors is about 0.7-0.8, and the frequency converter can increase it to above 0.95, reducing reactive power loss and lowering grid load.
