Q:Will the laptop's power adapter is not the original good?: As long as the power and current are equal or slightly larger than the original adapter, but the voltage must be equal to the original adapter on the line.

Q:My Lenovo v450 laptop power adapter should be bad how to match?: In order to ensure quality, we recommend that you buy genuine, you can contact the service station to buy engineers

Q:The laptop's power adapter is broken how much it costs: Buy a new, new price of dozens to one hundred. Notebook adapter, as long as the output current is greater than the old, the same voltage, with the brand can be interchangeable, Different brands of adapters to meet the above requirements, that is, insert the notebook connector is different, you can use scissors + tape,

Q:A water supply project, how to choose electrodes and frequency converters, such as giving a 7-storey water supply: 1. Select the pressure pump head: 7 * 2.5 (3) = 17.5 (21) meters; this is the number of theory, in fact, should be selected 40 meters, (0.4Mpa).

Q:Yaskawa inverter reported base blockade what is the reason?: Yasukawa compared garbage on the signal board on the small line of poor oxidation, and get like, this is a weak signal, and safety relays connected, do not use high-grade security circuit with a small line short, Yasukawa A 1000 factory is short for a long time after the oxidation of the base blockade

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:Notebook power adapter on how to look at power: then the same formula can be used to calculate: power (unit: W) = voltage (unit: V) × current (unit: A). For example: the power adapter only identifies the output voltage is 20V, the output current is 4.5A, then we set a formula to know the output power is 20 × 4.5 = 90W.

Q:Who knows how the frequency converter works: Rectifier circuit The function of the rectifier circuit is to convert the AC power into a DC power supply. Rectifier circuit is generally a separate rectifier module.

Q:Motor nameplate on the standard 2P, I set the number of motor pole in the inverter, is set 2 or 4 pole?: n the motor pole, an Antarctic (S pole), an Arctic (N pole), calculate a pair of poles, the number of pole pairs is how many such "pairs" (S pole + N pole). 2 pole motor --- pole pairs 1 = P = 1,4 pole motor --- pole pairs 2 = P = 2, and so on.

Q:Why the notebook power adapter can not be universal: Second, the voltage is different Different brands of laptop power adapter voltage is not the same, for example: under normal circumstances IBM is 16V, Dell is 20V, Hp is 18.5V, Sony is 19.5V and so on. Thus, even if the power adapter interface is the same, can not use different brands of laptop power adapter for power supply.
