Vector Control Variable Frequency Converter Drive Phase for Blower

ACI Vector Control Blower Variable Frequency Converter

Vector Control Blower Variable Frequency Converter is a device that combines vector control technology and frequency conversion technology to drive loads such as fans, achieving efficient and accurate motor control.

Working Principle

• Field Oriented Control (FOC)
  By using coordinate transformations such as Clarke transform and Park transform, the stator current of a three-phase AC motor is decomposed into torque and magnetic flux components, achieving independent control of the motor's magnetic field and torque.
  Simulate the control method of DC motors to enable AC motors to have similar dynamic performance and speed range as DC motors.
• Frequency Conversion technology
  By changing the output frequency and voltage, adjusting the motor speed, and adapting to different working conditions.
  Combined with vector control, more precise torque and speed control can be achieved, especially maintaining high torque output at low speeds.

Functional Features

• High precision control
  Vector control enables the motor to achieve precise torque and speed control over the entire speed range, meeting the dynamic adjustment requirements of loads such as fans.
• Significant energy-saving effect
  Real time adjustment of motor speed according to load requirements to avoid energy waste, especially in variable torque loads such as fans, where energy-saving effects are significant.
• Low speed high torque output
  Even at low speeds, it can provide sufficient torque to ensure the stability of the fan during start-up and low-speed operation.
• Fast dynamic response
  Vector control technology enables the system to respond faster and adapt to rapid changes in fan load.
• Protection function
  Equipped with overcurrent, overvoltage, undervoltage, overload, overheating and other protection functions to ensure the safe operation of the equipment

Fan application

• Air regulation
  By adjusting the motor speed and precisely controlling the fan airflow, different process requirements can be met.
• Pressure control
  In systems that require constant pressure, the frequency converter can adjust the fan speed in real time to maintain pressure stability.
• Soft start/soft stop
  Avoid mechanical shock during motor start and stop, and extend the service life of the equipment.
• Multi motor synchronous control
  Support synchronous operation of multiple wind turbines to ensure system coordination.
• Communication interface
  Supports communication protocols such as Modbus and Profibus, facilitating integration with upper computers or PLCs for remote monitoring and control.
