Sensorless vector control is also called as field-oriented control that this technique is widely used in electric industry for controlling motors. It controls electrical motors without position or velocity sensors that it usually controls the motor via constant volts per Hz control, open-loop flux-vector control as well as sensorless flux-vector control method. Sensorless vector control adjusts the frequency, amplitude and phase of the motor drive voltage. It’s capable of controlling the flux vector and current independently.

High Quality Wholesale Sensorless Vector Control AC Inverter

Sensorless vector control inverter is commonly applied in many areas such as punching mechanical, fans, textile, chemical industry, pump and more. By using a sensorless vector control inverter in on your equipment controlling system, it can automatically adjust the output voltage in order to decrease energy consumption cost.

On the global market, there are various manufacturers supplying sensorless vector control frequency inverter such as Veichi, Siemens, Hitachi, Fuji and more. In this article, we’ll take the Veichi AC70 sensorless vector motor control inverter for example.

Main Features of Veichi AC70 Vector Motor Controller

As a report shows, Veichi Electric is one of the Top 3 suppliers of variable frequency drives in China. It is a high-tech enterprise founded in 2005 with a full range of electrical automation products such as AC frequency inverters, servo drive, HMI, PLC, photovoltaic inverter and more electrical control products. AC70 is one of its best-selling models which have a good reputation in China and overseas market. Up to now, AC70 has gained more than tens of thousands of application examples.

1. Support V/F Control Mode

Veichi AC70 is a general purpose inverter that it needs to meet various kinds of application requirements of different industries, so it has been specially designed with multiple control algorithms such as V/F control, vector control and PID control.

When there is no high requirement in fast response and high accuracy speed control, V/F control mode is recommended. In case like this, it can be connected to several motors at the same for controlling.

2. Support without PG

This method is available for variable speed control which requires high accuracy speed control. When you set the inverter to this mode, it will enable you to achieve high torque response. It even has large torque when the motor is running at very low speed. It has been widely used for controlling punching machines.

3. PID Control

PID control can be divided into common PID control and pressure close-loop PID control. It has a wide application range and strong pertinence. This method is widely used to control the fans, pumps, air blowers and so forth.

Veichi AC70 sensorless vector motor control has high working stability, high accuracy control, strong environment suitability and user-oriented interface that it is very popular in electrical control area. If you are interested in Veichi and AC70, please go to our website to learn more.
