What is a variable frequency drive?
Jun 16 , 2022

Variable frequency drive (VFD) is the application of frequency conversion technology and microelectronics technology to control the electric drive components of AC motors by changing the frequency and amplitude of the working power supply of the motor. The frequency conversion technology was born under the wide demand of the stepless speed regulation of the AC motor due to the large volume, high f...

Why use a variable frequency drive VFD?
Jun 16 , 2022

1. Reduce energy consumption and energy costs If your application does not require full speed operation, you can reduce energy costs by using a variable frequency drive to control the motor, which is one of the advantages of variable frequency drives. VFDs allow you to match the speed of motor-driven equipment to load requirements. No other AC motor control method will allow you to achieve this. 2...

How to choose a variable frequency drive?
Aug 21 , 2022

The variable frequency drive generally chooses a 4-level motor, the base frequency operating point is designed at 50Hz, the frequency is 0-50Hz (speed 0-1480r/min) The motor runs at constant torque, and the frequency is 50-100Hz (speed 1480-2800r/min). The motor runs at constant power within the range of min), and the entire speed regulation range is (0-2800r/min), which basically meets the requir...
