Variable-frequency Drive (VFD) is a kind of power control equipment that controls AC motor by changing the working power supply frequency of motor. Its core functions and principles are as follows:
effect
control motor speed : By adjusting the frequency and voltage of the power supply, the inverter accurately controls the running speed of the motor, so as to meet different production needs and improve production efficiency and product quality.
energy saving : The inverter can automatically adjust the motor speed according to the actual load and power demand of the motor, reduce the loss of frequent start and stop of the motor, and realize energy saving and emission reduction.
protect the motor : by controlling the start and stop of the motor, reduce the shock and voltage fluctuations during startup, and extend the life of the motor.
reduce noise and vibration : the frequency converter can reduce the noise and vibration of the motor when starting or braking, improve the operation stability and reduce the equipment failure rate.
precise control : The inverter can precisely adjust the speed and torque output of the drive motor, adapt to the work needs under different load conditions, especially suitable for the scene
