ZFeng 900 Series 15Kw-T-G General Vector Variable Frequency DriveVariable 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.
Our company is committed to providing users with efficient and
reliable industrial automation products and energy efficiency
improvement solutions. We are a leading brand supplier in the
fields of building materials and ceramics, non-ferrous metals,
mechanical equipment, urban water supply, and injection molded
rubber. The frequency converters developed and produced by our
company are widely used in the energy-saving and environmental
protection industry, new energy industry, and high-end equipment
manufacturing industry.
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.
