Q:Speed regulation method of three - phase asynchronous motor
1, frequency control, with the inverter, power 2, change the magnetic pole logarithm, not feasible. 3, stator series resistance, energy consumption
Q:Inverter alarm a043, how is it
Check processing: Check if the cable is disconnected. Check the tachometer to shield the ground. The shield is not only on the motor side, but also on the inverter side The cable of the pulse encoder should not be disconnected. The pulse encoder cable can not be laid together with the power loop cable. Use only the recommended pulse encoder.
Q:How is the notebook with a power adapter?
Refer to the following factors when purchasing: Choose the brand: The principle is to choose the same type with the brand, if not, it can only find other brands. Now online to sell a lot of notebook power adapter are cut corners of the substandard products, the normal use of what should be no problem, once the accident will burn your laptop, save dozens of pieces but burn thousands of pieces of notebook worth the candle. (Such as the actual only 19V3.42A, but the standard 19V4.74A, this will lead to a very slow charge, and even damage the battery and laptop computers. There are some protection removed, this more horrible, there Accidentally burn the laptop.
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:Laptop power adapter (no power supply, but indicator light)
There may be reasons for the power adapter, there may be a computer can not identify the power supply is battery-powered or AC power. These are just speculated by your phenomenon, if you are better in the warranty period to the customer service test, so the best
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 meaning of the bipolar polarity in the inverter ah There is a +10V signal input is a -10V What is the meaning of ah?
Bipolar input is positive and negative. Bipolar input is generally used to directly through the external reference or potentiometer to achieve the motor forward and reverse switching, without having to switch all the way to switch the signal (switch).
Q:Three-phase asynchronous AC motor speed control method
Second, the frequency control method Frequency control is to change the frequency of the motor stator power supply, thus changing its synchronous speed control method. Frequency converter system can be divided into AC - DC - AC inverter and AC - AC inverter two categories, most of the current domestic use - cross - frequency converter. Its characteristics: High efficiency, no additional loss during the speed control process; Wide range of applications, can be used for cage type asynchronous motor; Speed ​​range, the characteristics of hard, high precision; Complex technology, high cost, maintenance and repair difficult. This method is suitable for applications requiring high precision and better speed performance.
Q:How to learn the inverter debugging and design parameters
You can find the basic inverter manual, see a few times to try, under normal circumstances, the inverter on the use of manual functions such as research to understand that most of the applications are no problem.
Q:Motor a speed, the inverter will burn what is going on, the inverter is a large yuan
If you buy the inverter and the motor can match, it is certainly the quality of the inverter.
