FAQ

Servo control system can give the inverter signal,

but want two motor synchronization, it should be impossible, the converter does not reflect so fast, and the speed is not so stable.

Is the laptop power adapter AC and DC?

In the power adapter has a nameplate, marked above the power, input and output voltage and current and other indicators, with particular attention to the input voltage range, if the nameplate indicates that the input voltage is AC 110V, then in China's 220V mains voltage Plug it will burn.

What is the application of variable frequency speed control?

Generally used in the need for continuous speed control of the place. With the general exchange of motor than its advantages is able to continuously speed. DC motor, although also continuous speed control, but the price is expensive, the volume weight is too large.

Which machines are used for the frequency converter

Frequency converter is widely used in the speed regulation of AC motor.Varameter speed control technology is an important development direction of modern power transmission technology, with the development of power electronics technology, AC frequency conversion technology from theory to practice gradually mature. Inverter not only smooth speed, large range, high efficiency, start current is small, smooth operation, and energy saving effect is obvious. Therefore, the exchange frequency control has gradually replaced the traditional traditional slip speed, variable speed control, DC speed control system, more and more widely used in metallurgy, textile, printing and dyeing, smoke machine production lines and buildings, Water supply, air conditioning and other fields.

Is the motor having a variable frequency motor and a variable voltage motor?

Motor with DC and AC motor, variable frequency motor and fixed frequency motor, string motor, that is, I have not heard of a transformer motor.

My Lenovo v450 laptop power adapter should be bad how to match?

Hello, this is not recommended to go online to buy. The original is too expensive, generally with the domestic voltage instability may occur, so I suggest you go to the computer city to buy. Generally good quality, to about 120. The The As for the model, you can look at the output power, or you take your bad adapter to go, people see a look. The The The You can use a few years no problem, power adapter this kind of thing, online to buy the replacement is not convenient. The Hope to help you

Old printing machine transformation, 37KW6 polar frequency motor with brake, inverter 55KW, now found running,

The frequency is too low or the brake gap is small

Laptop computer about electricity no electricity, is the power adapter problem?

"The adapter light is bright" is just a matter of line between the AC power supply and the power adapter, and the power adapter to the computer that line may be bad or the computer interface is not good. Practice shows that the adapter's computer interface where the line is most likely broken
