Product Description

THE WORKING PRINCIPLE OF A FREQUENCY CONVERTER
A Variable-frequency Drive (VFD) is a power control device that integrates frequency conversion technology with microelectronics technology.

It achieves precise control of an AC motor by altering the frequency of the motor's power supply. The internal structure of a VFD is complex,

mainly consisting of components such as rectification (converting AC to DC), filtering, inversion (converting DC back to AC), braking units,

drive units, detection units, and microprocessor units. The core working principle relies on the switching of internal IGBTs (Insulated Gate

Bipolar Transistors) to dynamically adjust the voltage and frequency of the output power supply.This allows the VFD to provide an appropriate

power supply voltage according to the actual requirements of the motor, achieving energy savings, speed regulation, and other objectives.

Additionally, it features multiple protection functions such as overcurrent, overvoltage, and overload protection, ensuring the safe and stable

operation of the equipment. With the continuous improvement of industrial automation, the application of VFDs is becoming increasingly

widespread across various industries.

 

Key Features & Advantages

High-Precision Frequency Control
Achieve seamless speed regulation (0-500Hz) with dynamic response and ≤0.5% speed fluctuation, ideal for high-speed motors, CNC machining, and precision manufacturing.

Energy Efficiency & Adaptive Load Management
Equipped with advanced vector control technology, it boosts motor efficiency by 15%-30% and reduces no-load energy consumption by over 40% through AI-driven energy optimization.

Robust Stability & Durability
Wide voltage input tolerance (±20%) and built-in protections (overcurrent/overvoltage/overheat) ensure reliable operation in harsh environments (IP55-rated for dust/water resistance).

Smart Connectivity & User-Friendly Operation
Supports industrial protocols (Modbus, CANopen) for seamless integration with PLC/SCADA systems. Features a 7-inch touchscreen for real-time monitoring, parameter configuration, and diagnostics.
