Can a regular motor be speed-controlled using a variable-frequency drive?
A regular motor can achieve variable-frequency speed regulation. However, it is not advisable to use it at low frequencies (below 30 Hz) for a long time as it may cause the motor to overheat and burn out.

What are the requirements for the installation and use of a variable-frequency drive?
The operating environment temperature is between -10℃ and +40℃. When the temperature exceeds 40℃, it should be reduced by 3% per degree Celsius. The maximum temperature should not exceed 50℃. The relative humidity of the air should be less than 90%, without condensation. The inverter can operate at its rated power when installed at an altitude of 1000m or below. When the altitude exceeds 1000m, it should be reduced by 1% per 100m in proportion. It should b...

Why does a variable-frequency drive have a leakage current when operating with a motor?
With the absence of a variable-frequency drive, the magnitude of leakage current is typically negligible. However, when employing a variable-frequency drive, the high switching frequency of the inverter's power module introduces higher-order harmonics into the output current. Furthermore, due to the presence of inductance between cables and ground as well as between different cables, a significantly larger leakage current (up to 10 times that observed ...

Can a single-phase 220V inverter output a three-phase 380V?
It can't be. The single-phase 220V inverters are capable of generating a three-phase output ranging from 0 to 220V, without incorporating any voltage boosting functionality.
