Why there is no output voltage after the inverter is powered on?
The fault of the inverter with no output is relatively broad in terms of fault mechanism and circuit level. The inverter has no U, V, W phase voltage output, but there is normal voltage between P and N of the main circuit (both ends of the energy storage capacitor), the high voltage indicator light is on, the inverter has entered "normal working status", and the mainboard MCU has also made a Based on this judgment, no relevant fault codes or abnormal instructions will be reported. The fault is puzzling: the circuit is normal, but there is no output, and it is difficult to find the fault link!

The difference between frequency converter and inverter
Generally, an inverter converts DC power into an inverter power supply with a certain frequency and voltage. The inverter with adjustable frequency and voltage of the inverter power supply is called a frequency converter.

Matters to note when installing the inverter
During the operation of the inverter, it outputs large power, consumes high energy, and generates a large amount of heat. In order to enhance the working performance of the inverter and extend its service life, installation should be carried out strictly in accordance with the inverter's user manual. At the same time, The basic installation principles and installation methods of the frequency converter should be followed for installation.

How to keep permanent magnet motors working properly
In actual work, the current of the machine and equipment is normal when it starts running. After a period of time, the current becomes larger. After a long time, the frequency converter will be reported as overloaded. First make sure the inverter is selected correctly, and then confirm whether the parameters in the inverter have been changed. If there is no problem with both, you need to judge by the back electromotive force, disconnect the machine head from the motor, perform no-load identification, and run to the rated frequency without load. The output voltage at this time is the back electromotive force. If it is lower than the value on the motor nameplate If the back electromotive force is above 50V, it can be determined that the motor is demagnetized.

Motor driven by the inverter overheats solutions
In the actual production process, why do motors driven by frequency converters overheat? This is because the voltage driven by the inverter contains rich high-frequency components.
