FAQ

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.

55 瓩 4 pole motor with a frequency of one hour can save much electricity

It depends on what type of equipment you use, the average energy-saving fan pumps, about 25-40 between; generic class is based on the frequency you use to decide, according to the frequency you use with 50 Hz Compared to energy saving.

30 kW 6 pole frequency motor torque is how much

To know what is the use of ah, the inverter motor is the same with the ordinary motor, but to prevent the operation of a low speed plus a fan

Is the number of Amps of the notebook power adapter higher than the original number of security on the computer?

There is no power adapter is not the number of clocks that the current output of the current frequency is the number of security in the case of the maximum number of output support the specific output current is the number of security is based on the current power consumption of the computer But please note that the power adapter output voltage must be consistent with the original agreement is now generally 20V

Please recommend a high performance laptop power adapter?

Power adapter can recommend you what model you get what model ah he is a standard can not just recommend

Is the laptop power adapter high temperature normal? Is there anything else?

Summer heat is normal, as long as it is not the kind of hand touch on the bubble temperature, no problem

What is the difference between AC and DC frequency converters?

Inverter air conditioner is relatively speaking in terms of ordinary air conditioning, ordinary air conditioning compression motor using AC induction motor, speed unchanged, 50HZ when the speed is about 2880r / min. The inverter air conditioner is the first 220V, 50HZ single-phase AC into three-phase inverter AC (25 ~ 118HZ, 56 ~ 160), the supply of compressors, through the frequency changes to adjust the compressor speed, so that continuous cooling capacity to adapt to air conditioning Load needs. L inverter air conditioner works: inverter air conditioner compressor by the variable frequency motor drag, the power inverter output frequency changes in the alternating current to the motor, so that the motor speed can be based on the needs of indoor cooling and continuous change, the final compressor cooling capacity To achieve continuous changes in the automatic control. In order to meet the continuous changes in the cooling capacity, the refrigeration system uses an electronic expansion valve, the pulse motor switch valve core, rapid control into the evaporator refrigerant flow. Power frequency changes from the inverter to achieve, as shown in Figure 1: 220V, 50HZ of the mains input, the frequency converter A / D AC / DC conversion, D / A inverter, the output frequency required by the three-phase alternating current, Room switching power supply principle is similar.

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.
