【Question】What is the influence of carrier frequency on inverter and motor? 【Answer】1. The influence of carrier frequency on the output current of the inverter (1) The higher the operating frequency, the larger the duty cycle of the voltage wave, and the smaller the higher harmonic component of the current, that is, the higher the carrier frequency, and the flatness of the current waveform.

Because the waters are intersected and connected, the waste discharged by each country and region is concentrated in the deep sea, and marine garbage has long become a global problem. Most of the marine debris is concentrated in five untouched areas, each of which falls in the Pacific Ocean of China, which is larger than the ...

In the process of motor starting (acceleration), the motor should not only bear the load torque of steady speed operation, but also bear the acceleration torque, if the production machinery has no special requirements for the starting (acceleration) time, the starting (acceleration) time can be appropriately extended to avoid the peak current. If the production machinery is ...

The cause of the leakage problem We all know that the three-phase stator winding of the motor flows through the current to produce a rotating magnetic field, according to the principle of magnetoelectric induction, the shell of the motor will produce an induced electromotive force, the size of this electromotive force depends on the size of the switching frequency of the inverter IGBT, due to the high ...

Why should the fan be equipped with a frequency converter? Today, I will discuss it with you. Factory boiler fans, industrial fans, hotel fume fans, etc. all use inverters, so why do fans use inverters? We all know that many air ducts will have a valve, control ...

When we are repairing the inverter, we often encounter the inverter that triggers the overvoltage protection, at this time, I often wonder, can the overvoltage protection measures be different because of the overvoltage? (1) For the interrupting overvoltage of the phase-shifting transformer, the resistor-capacitance absorption network and oxygen ...

Can a small flow ultrasonic flow meter be used for flow measurement of soybean oil? There are several steps in the processing of edible oil that require the use of flow meters to measure the volume and weight of how much oil flows out of the pipeline. Enterprises that produce and process edible oil need to be aware of the crude oil and ...

Fujifilm ultrasonic flowmeter probe installation method and orientation. There are generally two types of probe mounting: the V method and the Z method, and experience has shown that the V method has a higher measurement accuracy than the Z method without affecting the signal reception. Since the V-method probe is installed for precise positioning, the measurement error mainly comes from the flow regime and ...

1. Analysis of common faults in the main circuit The main circuit is mainly composed of three-phase or single-phase rectifier bridges, smoothing capacitors, filter capacitors, IPM inverter bridges, current limiting resistors, contactors and other components. Many of these common faults* are caused by electrolytic capacitors. The life of an electrolytic capacitor is mainly determined by the ...
