Seeking help with inverter issues
Thread Content
What is the relationship between voltage and frequency in vector control mode? For example, it is 380V at 50Hz; what is the output voltage at 15Hz? What is the output voltage at 65Hz? I’d like to ask, thank you.
As the frequency decreases, the voltage also decreases; as the frequency increases, the voltage increases. Because when the frequency decreases while the voltage remains constant, the flux increases, which causes the motor to overheat and get damaged.
In voltage-frequency ratio control, voltage is proportional to frequency; is this also the case in vector control? Also, can the voltage at 15 Hz and the voltage at 65 Hz be calculated?
Study, study – I’m very interested in this
