Q: The parameters of the inverter is 4, 6 motor can be used: Variable-frequency (VFD) is the application of frequency conversion technology and microelectronics technology, by changing the motor operating frequency mode to control the AC motor power control equipment.

Q: A 4-pole AC motor into a 2-pole AC motor, the motor is controlled by the inverter, to make the maximum speed of the 2-pole motor and the original 4-pole: If it is normal V / F control, then do not need to modify too many parameters to limit the frequency limit of 50%

Q: How to view the parameters of the notebook power adapter on your computer: The correct way to use a laptop power adapter 1. Try to avoid use in outdoor or harsh environments to prevent the adapter from being exposed or damp. 2. When you are not using the adapter, please unplug the power plug. Because, for a long time the power will let the adapter has been in working condition, will affect the end of life. 3. Although the adapter is a broadband operating voltage, marked from 100V-240V can be, but if the voltage is extremely unstable in the case of use, the same will cause damage to the power adapter

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: What is the difference between variable frequency motor and variable speed motor?: Give you a formula, you can understand their speed control principle: N (speed) = 60f (frequency) divided by P (magnetic pole logarithm) According to the formula, when you want to change the motor speed, there are only two ways to change The number of pole pairs and the frequency of the power supply. Speed ??motor is variable pole speed, that is, in this motor has 2 to 3 sets of windings, by changing the winding connection, to change the motor pole to change the rotation speed.

Q: Why the number of motor poles increased, the inverter capacity will increase: The relationship between the motor current and the power is The power is equal to the current and voltage of the product again good with the power factor. (Simplex)

Q: What are the AC motor speed control methods? What are the characteristics of each: 1, the frequency converter: smooth, according to the need to adjust the speed, is the future direction of the development of AC motor; (FM) 2, star, triangular connection conversion, generally in the larger motor start star start, triangular operation, Starting current. (Magnetic pole pairs) 3, there is a two-speed, three-speed motor, an increase of the winding, the main change in the stator winding connection to change the speed. (Change the number of pole pairs) The speed of change has two factors: magnetic pole logarithm, frequency

Q: ASUS and dell notebook power adapter can be universal?: You do not indiscriminate use as well, we recommend that you contact the after-sales department for your service.

Q: What is the difference between AC and DC frequency converters?: L inverter air conditioner refrigeration system components: inverter air conditioner by the compressor, evaporator, condenser, electromagnetic four-way valve, electronic expansion valve, defrost valve, double capillary and other components (see Figure II), work, air conditioner Room needs, automatic control of the inverter output frequency higher AC, the motor speed to speed up, the compressor cooling capacity increased to achieve the purpose of rapid cooling or heating, on the contrary, when the room cooling or heating less, Compressor to normal speed or lower speed operation, therefore, inverter air conditioner has a continuous cooling capacity adjustment, making the room temperature fluctuations smaller. In the process of compressor operation, the microcomputer system controls the inverter compressor at the same time, controls the opening degree of the electronic expansion valve, maintains the proper refrigerant flow, and directly changes the flow of the refrigerant in the evaporator to change its state, the compressor The speed corresponds to the opening degree of the expansion valve, and the displacement of the compressor corresponds to the supply amount of the expansion valve, so that the degree of superheat is not so large that the capacity of the evaporator is maximized, so that the refrigeration system The most efficient control.

Q: 18: 5 kilowatts bipolar multi-pole pump motor with inverter: If you worry about the small, with 18.5KW is far enough.
