Use single-phase to three-phase inverter
A device that converts alternating current with a fixed voltage and frequency into alternating current with a variable voltage or frequency is called a “frequency converter”
The equipment first converts three-phase or single-phase alternating current into direct current (DC). Then the direct current (DC) is transformed into three-phase or single-phase alternating current (AC).
The frequency converter changes the output frequency and voltage at the same time, that is, changes the n0 on the motor running curve, so that the motor running curve moves down in parallel.
Therefore, the inverter can enable the motor to obtain a larger starting torque with a smaller starting current, that is, the inverter can start a heavy load.
