- Q:I power adapter output current 3.25A for a 4.5A, can you use it
- Can provide a large current that the rated power is higher than the original landlord that can be assured that the use of the best, but the original oh a lot of cottage performance instability do not burn the notebook
- Q:Will the motor suddenly stop when the inverter is suddenly powered down?
- but there are exceptions, such as head pump, water hammer effect after power failure will make the motor Reversal
- Q:Motor a speed, the inverter will burn what is going on, the inverter is a large yuan
- Inverters Have not heard of it! East yuan heard. The inverter is most likely to be damaged by the motor is running suddenly grounded, the possibility of frying the module more than eighty percent, since a little better brand will blow up! Overload, overcurrent, short circuit, lack of phase caused by damage to the inverter, then the quality of the inverter is so good, and indeed the basic functions of these inverter protection.
- 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 power of the three-phase motor is equal to the root number of 3 times the line current and the line voltage of the product again good with the power factor. Can also be 3 times the phase current and phase voltage of the good product and then good to power factor.
The frequency converter should match the rated current of the motor, not the power of the motor.
- Q:Who knows how the inverter is calculated?
- The synchronous speed of the two-pole motor is 3000 rpm,
- Q:Is the laptop power adapter AC and DC?
- In the power adapter has a nameplate, marked above the power, input and output voltage and current and other indicators, with particular attention to the input voltage range, if the nameplate indicates that the input voltage is AC 110V, then in China's 220V mains voltage Plug it will burn.
- Q:Oil-free vertical vacuum pump why a little negative pressure inverter on the torque limit
- and then use the inverter into three-phase AC, 380 volts almost, Can only use the transformer rose to 380 volts.
- Q:Laptop power adapter output voltage is not the same as the current? What's the effect?
- I would like to elaborate on the basic principle of the large standard current power supply can replace the small standard current power supply. Some friends have misunderstood, that a large nominal current power will burn books, because the current big thing. In fact, how much current in the same voltage depends on the load, that is, the work of the books, when the books of high-load operation, the current larger, the books into the standby time, the current is smaller, in short, On the voltage divided by the equivalent resistance of the books. Large nominal current power supply has enough current margin, will not be replaced by a small standard current power supply after the overheating or output voltage is too low. On the contrary, with a small current power supply instead of high current power on the existence of the above risks. But some friends with 56w power supply instead of 72w with no problem, because the power adapter is usually designed to leave a certain margin, the load power should be less than the power supply,
- Q:The inverter is running independently
- . Main working circuit (1) Operation circuit: the external speed, torque and other instructions with the detection circuit current and voltage signal comparison operation, determine the inverter output voltage, frequency. (2) voltage and current detection circuit: isolation with the main circuit potential detection voltage, current and so on. (3) drive circuit: drive the main circuit device circuit. It is isolated from the control circuit to turn on and off the main circuit device. (4) speed detection circuit: mounted on the asynchronous motor shaft speed detector (tg, plg, etc.) signal for the speed signal into the operation loop, according to the command and operation can make the motor running at the command speed. (5) protection circuit: the detection of the main circuit voltage, current, etc., when the overload or over-voltage and other abnormalities, in order to prevent the inverter and asynchronous motor damage
