- Q:Ordinary 4-pole motor Under the control of the inverter, the higher the speed, the higher the power or the slower the power
- It is wrong; the higher the speed is not equal to the greater the power;
- Q:If it is 8-pole variable frequency motor, enter the motor nameplate parameters in the inverter input for the 4 pole can?
- If the control accuracy is not high, then you can use the ordinary control. Since the choice of the inverter, it is best based on the motor nameplate to set parameters to ensure the stability of the motor running
- Q:Laptop adapter heat
- Therefore, in the design and production of switching power supply, we must choose high temperature components. Of course, be sure to control the temperature of the power supply within the allowable range of the application environment. First, the conversion efficiency should be designed as high as possible, and secondly, to use the pressure drop is small, low loss of switching components, the third is to be thermal design, cooling area to be as large as possible, more than 100W switching power supply Should have a metal perforated shell, or add a cooling fan. The current notebook power adapter power is generally around sixty or seventy W, the use of high temperature plastic fire sealed package, the internal heat generated by the plastic shell mainly distributed out. Therefore, the power adapter surface temperature is still quite high, the maximum temperature or even reach about 70 degrees! Think of the inside of the adapter, it is not like the fire! So, when you use the laptop, try to place the power adapter in a better place to ventilate heat, do not put books and the like on the power above. As for the kind of hot feeling, do not have to worry about is the power, not angry strange!
- Q:What is the number of parameters of the motor frequency of the Siemens inverter?
- Siemens inverter motor pole number parameter code is r0313 motor pole pairs. Note that the number of pole pairs.
- Q:Will the motor suddenly stop when the inverter is suddenly powered down?
- Generally in the absence of external brake or brake case, if the power, the motor is in a free stop state, uncontrolled,will gradually slow down to 0
- Q:What is the difference when using inverter frequency conversion ordinary motor and variable frequency inverter motor
- First of all you have to understand the difference between variable frequency motor and ordinary asynchronous motor. 1, inverter motor cooling fan is not connected with the motor spindle, is independent, the fan rotation from the motor speed, to ensure that the motor cooling.
- Q:My motor is a low frequency 8 pole motor, about 80W. I would like to choose a frequency converter
- So small, with the domestic 400-watt, Shenzhen a lot
- Q:My inverter is the era TVF8000 series, the motor is 15KW6 pole motor, has been used for 3 years.
- If the frequency converter is selected according to the motor rated current, then the motor current exceeds the rated current, the inverter will become overcurrent protection In this case, that is, when the inverter began to select the amount of time to stay the lack of the same power, inverter general type than the fan pump type current capacity of a high grade If the inverter selection is no problem, then please see whether the inverter is working temperature is too high, too high will cause the electronic components to resist the decline in current. First, check the inverter to work the ambient temperature, the second Please check the inverter fan is damaged, clean down the inverter fan channel and fan to see if there is no plug
- Q:Can the laptop's power adapter be used for years?
- Generally 3 to 5 years is not a problem, good quality can be used for 10 years. Power adapter is a small portable electronic equipment and electrical and electronic power supply conversion equipment, generally by the shell, power transformer and rectifier circuit, according to its output type can be divided into AC output and DC output type; by way of connection Divided into wall and desktop. Extensive support in the phone son machine, game consoles, language repeaters, Walkman, notebook computers, cellular phones and other equipment.
- Q:What is the application of variable frequency speed control?
- Frequency control speed ratio is relatively large, in other words, the speed is accurate, smooth speed. Widely used, the basic works can be used
