This function makes the AC70 sensorless vector control inverter more energy-saving, eco-friendly and cost-effective.įor buddies who are interested in the AC70, please learn more information from the product page of AC70 vector inverter. Support both direct current and alternating current power supplyīesides alternating current, it also supports DC power supply. The Veichi AC70 is of three-proofing lacquer and IP20 (for higher level degrees, please ask for customization) which can be used in various kinds of application environment.Ħ. During the running status, AC70 can automatically calculate the voltage according to the loading status, so energy will be saved.ĥ. The AC70 is developed with the energy-saving control. This feature makes it available for applying in various application cases with professional performance. The Veichi AC70 is developed with PID control, including common PID and pressure closed-loop PID. On the basis of the function, it can allow the electric equipments obtain large starting torque, fast speed and high accuracy process control. ![]() Through the parameter settings, users are allowed to select rotating self-learning and static self-learning mode. Developed with advanced self-learning functions When the motor is running at very low speed, you can also obtain a large torque.Ģ. When you need high accuracy speed control, this motor control mode is suggested as it features fast torque response speed. ![]() This method can be applied in all variable speed control. Veichi AC70 also supports vector control without PG When the motor parameters are not known, the V/F control mode is recommended.ī. In this mode, several motors can be connected to a single VFD drive for achieving motor control purpose. This method is designed to meet the application requirements which don’t require fast response and high precision control cases. Veichi AC70 supports both vector control mode and V/F control mode Comparing with other vector inverters manufactured by international leading brands, the AC70 is of comparable stability, precision and dynamic performance.ġ. Veichi AC70 is one of the classic general purpose vector control drive that it offers 380V, 660V and 1140V 0.75KW to 1100KW models. Besides these brands, some Chinese electric corporations have also developed quality vector control drives such as Veichi AC70 sensorless vector control drive.įeatures of Veichi AC70 Sensorless Vector Control Drive Nowadays, the vector control algorithm is commonly used on variable frequency drives of Siemens, ABB, Allen-Bradley, GE, Fuji and more international leading level VFD brands. The sensorless vector control of AC drives is cost-effective and reliable that it requires derivation of rotor speed. According to statistics, the last one has been widely applied as it is easy to operate via the speed range from 0 to the maximum speed. The vector control includes direct vector control, feedback vector control, indirect or feedforward vector control. Nowadays, it is more and more popular in lower application cases. Vector control features rapid acceleration and deceleration with high dynamic working performance. It is also called as field-oriented control used to control AC synchronous and induction motors. Vector control is one of the most popular electrical motor control modes in electric industry that it is widely used to develop the variable frequency drives. It shows the vector motor control and one the of best sensorless vector control frequency inverters. ![]()
