Why is proportional to the voltage and frequency of the inverter changes

Any motor torque is current and the result of the interaction of magnetic flux, is not allowed to exceed the rated current value, or it will lead to the heating of the motor. Therefore, if the flux decreases, torque will be reduced, resulting in reduced load capacity.

E=4.44*K*F*N* by the formula φ can be seen in variable-frequency adjustable-speed motor magnetic circuit with frequency fX is in the context of considerable change, it is very easy to saturate your serious motor magnetic circuit, led to serious distortion of waveform of excitation current, peak is a high peak current.

Therefore, proportional to frequency and voltage to change, change the frequency-controlled inverter output voltage at the same time, keep the motor flux must avoid magnetic saturation phenomena of weak magnetic and. This control method for energy saving of fan and pump inverter.
