A general vector inverter is equipment that adjusts motor rotating speed by changing the frequency of input power supply for motors, which is widely applied in modern industrial automation.
Working Principle
The core technology of general vector inverters is vector control. It precisely controls motor torque and magnetic field, and dynamically adjusts motor speed following load fluctuation to achieve higher-efficiency and smoother operation.
Performance Advantages
Precise Control
Adopting vector control technology, the motor maintains highefficiency operation under low speed and heavy load conditions, realizing high-precision speed and torque control.
Energy Saving & High Efficiency
Compared with conventional fixedfrequency drive systems, the inverter runs stably in a wide frequency range, improving motor operating efficiency and cutting power consumption for energy conservation.
Strong Adaptability
It supports multiple control modes including sensorless vector control and V/F control to match diverse load requirements. Meanwhile, it accepts multiple frequency reference inputs such as analog signals, pulse signals and communication commands, adapting to complicated and variable industrial site conditions.
Comprehensive Protection Functions
It is equipped with complete fault selfdiagnosis and protection mechanisms covering overcurrent, overvoltage, undervoltage, overheating, phase loss, short circuit and other safety detections to guarantee long-term stable equipment operation.
