Distributorship are offered for your unique design and some our current models.

Q: The inverter control power is also the same, the pole is not the same as the motor 6 or 4 pole can be used?: Can be used, but is being used in the motor replacement, you need to change the frequency conversion.

Q: What is the difference between the electronic governor and the frequency converter on the motor speed regulation?: Probably the wider range of frequency converter applications! There is a more comprehensive protection of the motor on the inverter

Q: Can different brands of laptop power adapters be generic?: Power adapter can not use, the key to see two factors. First, the interface must first be the same interface or can not use. Second, the output current, the output current must be strictly consistent, otherwise it would be very dangerous, the laptop overload of the current is very fragile. The final output voltage I personally think can have a difference of type 5V. Because the battery on the voltage requirements up and down can have 5V floating. I have also used a high 5V adapter, has been no problem, but this is just my personal view. Strictly the same as the best. Oh, for reference only! Since you can plug in the normal use, indicating that the interface is consistent, and the output voltage and current are the same. Then I can responsibly tell you, rest assured to use it, there will be no problem.

Q: The laptop power adapter is hot: My point of view: First: your laptop power supply in a small ventilation environment, resulting in poor heat dissipation, Second: the life of the power supply is 3-5 years, the gradual oxidation of electronic components and some of the aging components, resulting in no load and load a lot of power, Third: the battery close to each run, and then connected to the power, the power to the battery charger and notebook power supply, so the pressure is not hot strange.

Q: What is the single axis of the inverter and multi-axis applications: The frequency changer mainly consists of rectification (alternating current direct current), filter, re-rectification (DC variable AC), brake unit, drive unit, detection unit micro-processing unit and so on.

Q: Is the laptop power adapter long-haul?: As long as the power, regardless of your access to the computer, the adapter is working. In fact, not much harm, anyway, five years of notebook life, this thing as long as not deliberately to damage, will be very durable, worse than the important parts of the computer slow. As long as the big brand, nothing Even if you broke, this thing can value a few money? In fact, the proposal or pull it, on the ground stumbling ... ...

Q: How to view your own laptop power adapter is how much tile?: 1, the power adapter has a logo, you can find their own look, close to the paper or direct letterpress printed with the voltage, current and power. If there is no write power, the direct voltage multiplied by the current is the maximum power. 2, if the power adapter only identifies the output voltage is 20V, the output current is 4.5A, then we formula W (power) = V (voltage) xI (current) to calculate. Calculate the formula with a power to know the output power is 20 × 4.5 = 90W.

Q: Yasukawa inverter reported bb code that is the reason why the base blockade?: This should be the meaning of the drive block, that is, the drive signal is locked, there is no drive signal, and start a frequency change but no voltage output, you find someone to repair the circuit board can be used normally, this is generally the circuit board Problem, the module is less likely to be bad

Q: Speed of 3000 r / min three-phase motor how to change its speed: The key lies in two points: 1, you ask the variable range is how much? 2, your motor had a few qualifying? If your motor is 6 outlet, and you only need to speed, plus your motor is also an asynchronous motor, and you do not have the requirements of the load; then congratulations, you can achieve "speed" You just put the motor wiring way to do a △ - Y or Y - △ conversion can be achieved. If the above conditions you have one or two can not meet, then your best way is to buy a drive to achieve the variable speed. Of course, you can also make some changes to the winding to achieve the so-called single-winding multi-speed operation (this change, but the need for a certain technical content).
