Tips of Frequency conversion Technology(3)

When the motor is driven by a power frequency power supply, the voltage decreases and the current increases; for the inverter drive, if the voltage also drops when the frequency drops, does the current increase?

When the frequency drops (low speed), if the output is the same power, the current increases, but under certain torque, the current is almost unchanged.
