The concept of an inverter or motor speed controller

An inverter or AC drive is a device that can be used to control the speed of a three-phase AC motor without reducing the power and torque of the motor. Inverters are made in different capacities. Also, with the rapid development and constant reduction of prices in the field of power electronics, the ground is provided for their widespread presence in industrial, transportation, and even household applications.

The driving force of most pumps, fans, or any device that requires external driving force is usually supplied by induction motors that work at a constant speed. But in recent years, with the progress made in the field of power electronic technology, the use of induction motors with the motor speed controller (AC DRIVE) or inverter is expanding.

Drives are devices that convert input power with constant voltage and frequency to output power with variable voltage and frequency. It should be noted that the speed of a motor is a function of the frequency of its power supply. For this reason, a drive first converts the mains electricity to DC voltage and then converts it again to AC voltage with variable frequency and voltage using an inverter. In a low-voltage drive, the inverter part consists of power switches that generate the output signal with the desired frequency by alternating switching. These keys have undergone many technological changes in recent years. With the introduction of power switches such as IGBT, which brings both the ability to work at high power and high switching speed, the ground was provided for the design of drives with a reasonable price and better performance.

Getting to know the types of Drive Ac

f or voltage over frequency

This model of AC drives is usually used in simple operations and to achieve general goals. In fact, this type of AC drive works by using a proportional table and it helps you to set and control the proportional speed of the operation by considering the frequency that it gives to the electric current.

SLV or sensorless vector drives

Another type of AC drive is a sensorless vector drive. In this method, the drives give us voltage feedback (in this method, we will not have speed and acceleration feedback.) Vector drives have a lot of torque and have low and low speeds. Therefore, they can be used to control heavy electrical loads. Using this method helps reduce the percentage of the possible error to less than one percent.

CLV or feedback drives with sensors

Unlike the above two models, CLV drives have feedback. Therefore, they are able to receive the signals from the device and electric motors and hence they can detect the speed and position of the motor. Another feature of this drive is the ability to change the output to reach the desired output.
