ZFeng 900 Series 11Kw-T-P General Vector Variable Frequency Drive
The ZFeng 900 series vevtor variable frequency drive developed and
produced by our company combines the principle of mechanical
motion. Based on command settings, sensor signals, electric shock
signals, internal monitoring signals, etc., it automatically
adjusts the output power frequency through microchip calculation,
changes the motor performance and status, achieves one click energy
saving, and improves energy efficiency; The comprehensive
energy-saving rate ranges from 10% to 50%, saving you electricity
costs and reducing carbon emissions.
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.
