FAQ

Laptop adapter heat

Many friends to buy a laptop or laptop power, you may encounter the power did not take long to heat on the hot, and even hot to dare not get the situation, in the end is the quality of power problems or how is it? With the ever-changing notebook frequency, notebook power adapter power is also sesame flowering high, even to 100W or so, almost a small desktop power! Touch the hand, timid may be scared, obediently, is simply a hot potato! What will not fire? This is a lot of people worry! Compaq, IBM, such a large company to recover several back to the power adapter, it is because of fear that there may be defects due to power supply design, and will cause a fire!

Inverter 0.2KW, the motor speed requirements down to 4 turn, the motor pole 4 pole. Can the drive drive the motor?

You can only use constant torque type of inverter. Motor selection frequency conversion motor. Driving is no problem

Laptop power adapter leakage

In fact, the adapter does not matter fake real goods, brand machine adapter are also purchased. According to my point of view, or I choose the words: casually buy one can, dozens of dollars on the line. In fact, the adapter is also worth tens of dollars, selling a few hundred dollars are also almost the same thing. Adapter is a small switching power supply, 100W or so, the value of that price.

The motor is 2 pole with the inverter frequency to 50hz why the speed is only 1500 rpm

Hello, poles (a pair of pole) motor, the theoretical speed of 50 rpm when the theoretical speed of 3000 r / min, if the display shows only 1500 rpm, it is possible to have a motor shaft speed or speed device Yeah, gear ratio of 2 to 1 ,

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.

Do you want to pay attention to the number of poles of the motor when selecting the inverter?

Inverter is generally selected by the power, do not consider the number of poles, but the inverter output current is controlled by the module, so you can choose in the selection as much as possible in accordance with the rated current to select the inverter. And left redundant party B overload and other phenomena.

What is the single axis of the inverter and multi-axis applications

Inverter is the application of frequency conversion technology and microelectronics technology, by changing the motor power supply frequency and amplitude of the way to control the AC motor power transmission components.

How do I protect the inverter when the three-phase two-pole motor is running?

Three-phase two-pole motor running inverter protection, should be based on the protection of tips, check the corresponding manual to deal with. When the inverter protection has a corresponding protection tips (such as over-current, over-voltage, speeding, stall ... ... etc.), the product manual will generally give the corresponding protection tips. According to these measures to check, deal with, you can solve the problem.
