ZF310 series Vector Control Low Voltage variable frequency drive

Vector control low-voltage inverter is a type of low-voltage inverter that uses vector control technology to achieve high-performance speed regulation of motors. Its core lies in the vector decomposition and independent control of the motor stator current, thereby achieving decoupling control of motor torque and magnetic flux.

Technical Principles

Field Oriented Control (FOC) is based on motor equivalent circuit and coordinate transformation theory, which decomposes the stator current vector of a three-phase AC motor into excitation current component and torque current component, and performs independent control separately. The specific steps are as follows:

Coordinate transformation: Convert the current in a three-phase stationary coordinate system to a two-phase stationary coordinate system (α - β) through a 3/2 transformation, and then convert it to a two-phase rotating coordinate system (d-q) through a Park transformation.
Decoupling control: In the d-q coordinate system, the excitation current component (Id) controls the magnetic flux, and the torque current component (Iq) controls the torque, achieving independent adjustment of magnetic flux and torque.
Inverter control: Generate three-phase AC power through pulse width modulation (PWM) technology to drive the motor to operate.

Characteristics and Advantages

High precision control: Vector control can achieve precise decoupling of motor torque and magnetic flux, with fast dynamic response and high speed regulation accuracy.
Wide speed regulation range: supports low-speed high torque output, suitable for frequent start stop and situations with large load changes.
Significant energy-saving effect: By optimizing magnetic flux and torque control, motor losses are reduced and energy utilization efficiency is improved.
Four quadrant operation: supports electric and power generation states, suitable for occasions that require energy feedback.

Application

Vector control low-voltage frequency converters are widely used in fields that require high speed regulation performance, including:

Industrial automation: CNC machine tools, textile machinery, printing machinery, etc.
Transportation: electric vehicles, elevators, electric forklifts, etc.
Energy sector: fans, pumps, compressors, etc.
Agricultural machinery: irrigation systems, greenhouse ventilation equipment, etc
