ZFeng 310 Series 0.75Kw-T General Vector Variable Frequency Drive
A three-phase frequency drive is a power electronic device mainly used to regulate the speed and torque of three-phase AC motors. It controls the operation status of the motor by changing the frequency and voltage of the power supply, thereby achieving precise control of the motor performance.
The working principle of a three-phase Variable Frequency Drive is based on the proportional relationship between the speed of the AC motor and the power frequency. By changing the frequency of the power supply, the speed of the motor can be altered. At the same time, by adjusting the voltage, the magnetic flux of the motor can be kept constant, avoiding damage to the motor due to overvoltage or undervoltage. Specifically, three-phase frequency converters typically consist of rectifiers, filters, inverters, and controllers. The rectifier converts three-phase AC power into DC power, the filter smooths the DC power, the inverter converts the DC power into adjustable frequency and voltage three-phase AC power, and the controller is responsible for controlling and regulating the entire system.
Key Features:
Precise speed regulation: Three phase frequency converters can achieve high-precision control of motor speed, meeting the needs of various industrial application scenarios.
Energy saving and consumption reduction: By precisely controlling the speed and torque of the motor, unnecessary energy consumption is reduced and the energy efficiency of the equipment is improved.
Improve equipment reliability: Adopt advanced control algorithms and protection functions to ensure stable operation of equipment and reduce failure rates.
Easy to automate control: The three-phase frequency converter is easy to integrate with control systems such as PLC and DCS, achieving automated control of equipment
Application
Three phase frequency converters are widely used in various industrial scenarios that require motor speed regulation and torque control, such as:
Numerical Control Machine Tool: Achieve high-precision speed control of the spindle and feed axis.
Printing equipment: Ensure stable speed and tension during the printing process.
Crane: Provides low-frequency high torque starting to ensure smooth lifting.
Conveyor belt: achieve multi-stage speed operation and energy-saving control.
Fan and water pump: achieve energy-saving operation by adjusting the speed.
Selection Guide
When choosing a three-phase frequency converter, the following factors need to be considered:
Motor parameters: Select the appropriate frequency converter based on the rated power, rated voltage, rated current, and other parameters of the motor.
Load characteristics: Different load characteristics also have different requirements for three-phase frequency converters. For example, constant torque loads require the selection of three-phase frequency converters with high overload capacity, while variable torque loads such as fans and water pumps can choose universal three-phase frequency converters.
Speed range and accuracy requirements: Determine the required speed range and accuracy requirements based on actual application needs. This will affect the control mode and performance indicators of the three-phase frequency converter.
Environmental conditions: Consider the installation environment of the three-phase frequency converter, such as temperature, humidity, altitude, etc. Choose a three-phase frequency converter suitable for environmental conditions to ensure its normal operation and service life.
