Q: 4 pole 380V 4-5.5KW frequency conversion motor and inverter about how much money, such as the use of electromagnetic speed motor comparison: About 2,000 yuan, electromagnetic speed and vector inverter can bring feedback

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 laptop power adapter? Is it the battery?: so that the book can be normal operation, or else you think the notebook is 220V Is the voltage at work?

Q: ABB frequency converter and the difference between domestic frequency converter: The objective lens is equivalent to the lens of the projector, the object is inverted through the objective lens, magnified real image. Eyepiece is equivalent to the ordinary magnifying glass, the real image through the eyepiece into a positive, magnified virtual image.

Q: Inverter with 2.2KW 6 pole motor. 1 minute 8 times reversing often burn the motor, how to solve. For the 2 pole 4KW motor is the same.: 7 seconds more than a change, too often. It is estimated that the inverter will not work. Suggest:

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: Delta VFD-A frequency converter motor number of poles set: The frequency parameters of the inverter motor are not set, because the inverter will automatically detect the number of pole pairs of the motor during operation, and it will not need to be set.

Q: The motor is 2 pole with the inverter frequency to 50hz why the speed is only 1500 rpm: Motor speed formula: N = 60f / p In the above formula N - the speed of the motor (r / min); 60 - per minute (s); F - power frequency (hz); P - pole pairs of motor rotating magnetic fields.

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: 400w 6-pole motor should be equipped with much of the inverter?: Under normal circumstances, the market are sold on the inverter are based on the common 4-pole motor matching, when to match the 6-pole motor, the inverter to a large power level, which is 400W of the first-class power 0.75KW, and so on
