Why Use Variable Frequency Drives

A variable frequency drive is a device that controls the speed of a motor by adjusting the frequency and voltage of the AC power supply. It can provide a more flexible, efficient, and energy-saving motor control solution, while extending the life of the motor and reducing operating costs. With the continuous development of industrial technology, variable frequency drive has become an important technical means widely used in various motor control systems.

The important reasons for the inverter change are mainly the following aspects:

1. Energy saving
The variable frequency drive can control the motor speed and output power of the load according to the actual demand of the load, avoiding the situation that the traditional fixed speed motor runs all the time, thus greatly saving energy consumption. Because when the load demand of the motor is low, the frequency converter can reduce the output power of the motor, and also reduce the current and voltage of the motor, so as to achieve the purpose of energy saving. At the same time, the variable frequency drive can also improve the efficiency of the motor at low speeds and reduce energy consumption.

2. Improve productivity
Productivity can be increased by using ac variable frequency drives. Since the variable frequency drive can adjust the motor speed and output power in real time according to the actual load requirements, the production efficiency is improved. At the same time, since the variable frequency drive can improve the efficiency of the motor at low speed, the output capacity of the motor is enhanced, and it can better adapt to the load requirements of the production line.

3. Wide speed range
Traditional motor drive systems usually require a mechanical speed change mechanism to adjust the speed of the motor, but the speed range of this method is very limited and requires regular maintenance and maintenance. In contrast, the frequency converter can realize the stepless adjustment of the motor speed by adjusting the frequency and voltage of the AC power supply, and the speed adjustment range is very wide, which can adapt to various load requirements. This stepless adjustment can also avoid shock and damage to the motor when starting and stopping, thus prolonging the service life of the motor.

4. Reduce noise and vibration
Variable frequency drives can reduce motor noise and vibration by controlling motor speed and load. This is because the vibration amplitude and noise of the motor are generally lower when running at low speeds. At the same time, since the variable frequency drive can control the start-stop process of the motor, the sudden impact of the motor is avoided, thereby reducing noise and vibration.
