High-Efficiency Low Voltage VFD Inverter | Energy-Saving 3-Phase 380V Vector Frequency Inverter For Industrial Motors

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.

High-Efficiency Low Voltage VFD Inverter | Energy-Saving 3-Phase 380V Vector Frequency Inverter For Industrial Motors 0

Technical Characteristics
Vector control technology

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.

Low voltage and efficient design

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.

Multi-functional integration
  • Protection function: Five fold protection against overcurrent, overvoltage, undervoltage, overheating, and short circuit, with a fault self diagnosis rate of over 99%.
  • Communication interface: Standard RS485/MODBUS, optional Profibus DP, EtherCAT, supports Industrial Internet of Things (IIoT) integration.
  • Expansion module: Some models (such as A600 series) support encoder feedback cards and PLC expansion cards to achieve closed-loop vector control.
Quantification of Energy Efficiency Advantages
Significant energy-saving effect

Taking the centrifugal pump driven by a 110kW frequency converter as an example:

  • Power frequency operation: The motor is always fully loaded, with an energy consumption of 110 kW x 8000 h=880000 kWh/year.
  • Variable frequency operation: Adjust speed according to flow demand, reduce energy consumption by 40% -60%, and save 352000-528000kWh of electricity annually.
Power factor optimization

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.

Typical application scenarios
  • constant pressure water supply system
    Through feedback from pressure sensors, the frequency converter automatically adjusts the speed of the water pump, maintaining a constant pressure in the pipeline network and achieving an energy-saving rate of 30% -50%.
  • Energy saving renovation of fan
    In the dust removal fan of the steel plant, the frequency converter adjusts the speed according to the flue gas volume, replacing the baffle adjustment, with an energy-saving rate of 45%.
  • Precision manufacturing equipment
    The spindle drive of CNC machine tools adopts vector frequency converters to achieve low-speed high torque (such as outputting rated torque at 0.1rpm), improving machining accuracy by more than 10%.
Selection suggestions and product recommendations
Selection of core parameters
  • Power matching: The rated power of the frequency converter is ≥ the rated power of the motor * 1.1 (considering overload capacity).
  • Voltage level: Three phase 380V input, output voltage is consistent with the rated voltage of the motor.
  • Control mode: Universal load selection V/F control, high-precision scene selection vector control.
