What is the starting current and starting torque of the motor when the inverter is used? The frequency and voltage are increased with the speed of the motor, and the starting current is limited to 150% rated current (125 / 200 according to the type of machine). When starting directly with power freq

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 incre

What is the difference between voltage and current? The main circuit of the converter can be divided into two types: the voltage mode is to convert the DC of the voltage source into the AC converter, and the filter of the DC loop is the capacitance. Current mode is a converter that converts the curr

What is a converter? Frequency converter is a power control device which converts the power frequency power supply to another frequency by using the on-off action of the power semiconductor device. What is the difference between PWM and PAM? PWM is the abbreviation of Pulse Width Modulation, which c
