Q:What are the differences and links between the soft starters and the frequency converters, and their respective principles and uses?
The frequency changer mainly consists of rectifying (alternating current direct current), filtering, re-rectifying (direct current alternating current), braking unit, driving unit, detecting unit micro-processing unit and so on. Motor asynchronous speed expression bit: N = 60 f (1-s) / p (1) Where n --- the speed of asynchronous motor; f --- the frequency of asynchronous motor; s --- motor slip; p --- motor pole pairs. From the formula (1) we can see that the output speed of the motor is related to the input power frequency, slip rate and the number of pole pairs of the motor. Therefore, the direct speed regulation mode of AC motor mainly has variable speed (adjustment P), rotor Resistance speed control or cascade speed or internal feedback motor (adjust s) and frequency control (adjust f) and so on. And we now use the most widely used is the frequency control, from the speed n is proportional to the frequency f, as long as the change in frequency f can change the motor speed, when the frequency f in the range of 0 ~ 50Hz, the motor speed adjustment range is very width. The inverter is to change the motor power frequency to achieve speed adjustment, is an ideal high efficiency, high performance speed control means.
Q:What is the laptop adapter
4, the working principle: the use of unstable power supply switching power supply principle through the conversion circuit into the notebook computer needs constant voltage DC, to the laptop computer power supply and charging; it is worth noting that: this conversion circuit, there must be protection circuit (Overcurrent protection circuit, overvoltage protection circuit short circuit protection circuit, etc.), to prevent accidents, the protection of the laptop will not burn.
Q:How can a variable speed multi - speed three - phase asynchronous motor be controlled by a frequency converter?
Although the waste, but can be used, we use the frequency band with two-speed motor when the output is connected to the fast three terminals, you can refer to the next
Q:The motor is 2 pole with the inverter frequency to 50hz why the speed is only 1500 rpm
Hello, poles (a pair of pole) motor, the theoretical speed of 50 rpm when the theoretical speed of 3000 r / min, if the display shows only 1500 rpm, it is possible to have a motor shaft speed or speed device Yeah, gear ratio of 2 to 1 ,
Q:3.7KW inverter with 2.2KW 6-pole motor running to see the inverter shows the current is more than 4A, with the amount of clamp to 2.8A
The inverter operates at constant speed below the base speed, and the output current of the inverter does not change as long as the load does not change.
Q:Quartet of the TA, TC terminals have positive and negative?
This can not be said to be positive and negative, should be called the public, TA, is the common.
Q:Acer laptop power adapter
It might be bad, you have to determine whether the adapter or adapter adapter directly change.
Q:Inverter ACS355 If the speed is outside the allowable range, how to set the limit value
2. Set the minimum speed allowed in 2001 MINIMUM SPEED.A positive minimum (or zero) defines two ranges, a positive range, A negative range. A negative minimum defines a speed range.
Q:65w adapter and 90w laptop power adapter What is the difference?
65W and 90W is mainly based on your laptop power configuration, the general integrated graphics with 65W, discrete graphics because of the need for additional power supply, so the general need 90W, of course, there are some low-power CPU, such as 25WCPU , 35W, 45W difference, these are the beginning of the manufacturer according to the notebook's power consumption count a maximum power, and then give your laptop with adapter 90W adapter can replace 65W, as long as the interface is the same, but 65W instead of 90W sometimes there may be insufficient power lead to automatic shutdown. In general, the greater the number of watts, the larger the head, because the adapter is actually a coil will be 220V into 19V, according to the power to determine the head, the larger the watt, the same 19V, then the output current will be greater
Q:What is the difference between the electronic governor and the frequency converter on the motor speed regulation?
Probably the wider range of frequency converter applications! There is a more comprehensive protection of the motor on the inverter
