Do I Need A Frequency Converter?

The term “variable frequency drive” (VFD) refers to an electric device that changes the frequency of an electric current from one frequency to another. Most of the time, the voltage stays the same before and after frequency change. Many times, frequency converters are used to control the speed of motors that power fans and pumps.

A frequency converter is an electric part that changes a current with one frequency to another frequency. Most of the time, the voltage stays the same before and after frequency change. Many times, frequency converters are used to control the speed of motors that power fans and pumps.
That’s how this works in the following case:

A current of 400 VAC, 50 Hz is sent to a fan. Once every 50 Hz, the fan can only go at a certain speed. A frequency converter is used to raise the frequency to, say, 70 Hz so that the fan can spin faster. If you want the fan to run more slowly, you can change the frequency to 40 Hz.

It is important not to plug electrical items into the wrong power source, or the smoke could escape from them. The smoke is like “a genie in a bottle”; once it comes out of the electronics, they can’t be put back in.Bigger and three-phase machines can’t work on the wrong frequency because it can damage them or wear them out faster than it should.

So, one of the main goals will be to figure out how to tell a real frequency converter from a fake one when using it on a car wash machine.

In fact, almost all merchants say they have a switch that they can use on the car wash machine. But it’s not a real frequency converter that can change the car wash machine’s power or speed. Most of the time, a 0.4-inch small motor is used on the moving part, and it can’t be set up to work with different types that have different levels of water pressure and fan speed. Even worse, if it doesn’t have a frequency converter, the instant current is 6-7 times the general current when the machine starts up. This can easily damage the machinery and waste electricity.

The CBK Cars Wash machine uses 18.5kw frequency converter technology to power itself. The High and Low pressure of the water sprays and the High and Low speed of the fans will save more than 15% of the electricity used, so the owner can set up any process he wants. Because of this, the CBK Cars Wash machine can cut down on the need for upkeep and the costs that come with it.

These days, anything with a motor needs a frequency converter. The CBK Cars Wash machine has one.
