ZFeng 900 Series 15Kw-T-P General Vector Variable Frequency Drive
Variable frequency drive (VFD) is a power control device that integrates frequency conversion technology and microelectronics technology. It achieves precise control of AC motors by changing the operating power frequency of the motor. The core working principle is to use IGBT (Insulated Gate Bipolar Transistor) to turn off and convert the power supply (50Hz or 60Hz) into AC power with adjustable frequency, thereby driving the motor to operate. The internal components of the frequency converter include rectifiers, filters, inverters, braking units, driving units, detection units, and microprocessor units.

Core Advantages
- Efficient and Energy-saving
Automatic adjustment of output power: The vector frequency converter can automatically adjust the motor speed and output power according to the actual load requirements. Under light or partial load conditions, reducing the motor speed can significantly reduce energy consumption. For example, in equipment such as fans and pumps, their load is usually proportional to the third power of the speed, and adjusting the speed through a frequency converter can achieve significant energy-saving effects. According to statistics, using vector frequency converters can save energy by 20% -50%, reducing production costs and improving economic benefits for enterprises.
- Precise Control
Decoupling control: Vector control technology can accurately control the excitation current and torque current components of the motor, decomposing the stator current vector of the asynchronous motor into the current component that generates the magnetic field (excitation current) and the current component that generates the torque (torque current), and controlling them separately. This can achieve precise control of motor torque and speed, enabling the motor to maintain stability and reliability during operation and improve production efficiency.
- Quick Response
Advanced control algorithm: Vector control technology adopts advanced control algorithms and high-speed computing processors, which can quickly respond to changes in motor speed and current. This enables the motor to achieve rapid response during start-up, speed regulation, and braking, improving the dynamic performance of the system.
