Open loop vector controlled frequency converter can achieve forward and reverse rotation of the motor. Simply changing the switching sequence of the inverter tubes inside the frequency converter can achieve output commutation, and there is no possibility of burning the motor due to improper commutation;
The torque efficiency of the motor is improved, and the motor speed is changed according to application conditions; Due to the adoption of high-performance digital signal processing chips, processing speed is improved and performance is stable, achieving sensorless vector control, and improving torque efficiency at low speeds.
It can be applied to industries such as textile and manufacturing.
