How to repair a motor that has been exposed to water or moisture

In actual production, the motor is affected by moisture due to improper storage and maintenance, temperature, environment and other factors. Water vapor enters the interior to form condensation beads or the motor directly enters water, causing the motor insulation resistance to malfunction and affecting actual production.

How to make the inverter survive from the summer

The hot summer is accompanied by high temperatures and scorching heat. Frequency converters are widely used in the electrical automation industry. High temperatures in summer bring high-frequency shutdowns and other faults to operating frequency converters and equipment. In actual work, as the ambient temperature rises, the frequency converter cannot dissipate heat in time and the failure rate gradually increases, and the use efficiency of components will decrease. Through comprehensive and multi-faceted analysis and summary, corresponding measures are formulated to prevent shutdowns and other failures in response to high temperatures in summer.

The highest frequency and basic frequency of the inverter

There are two definitions of fundamental frequency: a. The frequency corresponding to the maximum output voltage of the inverter is called the basic frequency; b. When the output voltage of the frequency converter is equal to the rated voltage, the minimum output frequency is called the basic frequency. The fundamental frequency is represented by fBA. In most cases, the basic frequency is equal to the rated frequency of the motor.

The Functions of frequency converter for motor

In daily production activities, ordinary production workshops have harmonics, voltage instability, overcurrent, etc. The motor is easily damaged and production is affected. This is where the frequency converter comes into play.

In production, why the frequency can't be adjusted?

In actual production, the frequency of the inverter cannot be adjusted up, generally because the maximum torque output by the inverter is less than the load lifting torque.

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!
