ZFeng 900 Series 18.5Kw-T-G General Vector Variable Frequency Drive

The universal frequency converters produced by our company are used in a wide range of industrial scenarios, such as conveyor belts and machine tools, and usually have higher instantaneous overload energy (such as 150% -180% short-term overload) to meet complex load requirements.

G-type numerical (suitable for load balancing scenarios (general class) motors, with a focus on dynamic response parameters.

Energy saving and speed regulation functions of frequency converters

Frequency converters play a crucial role in the field of industrial automation, with core functions including speed regulation and energy conservation. By changing the operating power frequency of the motor, the frequency converter can achieve stepless speed regulation, meeting the precise requirements of the production process for motor speed. At the same time, the frequency converter can adjust the power supply voltage and current of the motor according to actual needs, ensuring that the motor operates in the optimal state and effectively reducing energy consumption.

Protection function of frequency converter

The frequency converter is equipped with multiple protection functions such as overcurrent, overvoltage, overload, undervoltage, grounding, short circuit, overclocking, and stall, ensuring the safe and stable operation of the equipment. For example, when the motor experiences overload or short circuit, the frequency converter will quickly cut off the power supply to avoid motor damage. In addition, the frequency converter also has a soft start function, which can reduce the impact of starting current on the power grid.

Control method of frequency converter

There are various control methods for frequency converters, including V/F control, vector control, direct torque control (DTC), etc. V/F control controls the speed and torque of the motor by the ratio of constant voltage to frequency, which is suitable for general speed regulation situations; Vector control separates the magnetic field and torque of the motor, achieving higher precision speed and torque control, suitable for high-performance applications; DTC real-time control of motor torque and speed, providing fast dynamic response, also suitable for high-performance applications.
