Q:ASUS and dell notebook power adapter can be universal?

I can not remember to insert into the ah. The Looks like DELL that interface is very special

Q:Can the laptop power adapter be generic?

Output voltage, current, interface can be used as well.

Q:The laptop power adapter is hot

Almost all of the notebook adapters have this problem, you do not have to worry about this. But do not know you can not tolerate what is the degree, if it is so hot that the adapter has a deformation, then it is recommended to immediately stop using, to the sale to the new

Q:Who knows how the inverter is calculated?

The synchronous speed of the two-pole motor is 3000 rpm,

Q:Does the teacher know the working principle of the inverter?

The frequency converter is an AC-DC-AC power electronic device that converts 50 Hz AC sine wave into straight high voltage direct current and then converts it into an AC power that can control the voltage and frequency, driving the three-phase AC motor.

Q:90KW inverter start 90KW, 4-pole motor and 6-pole motor j What is the difference? The inverter can be used for it?

Three-phase AC induction motor, 4-pole speed is generally 1480 rpm, 6-pole speed was 980 rpm

Q:What is the motor series parameter setting of the inverter? If it is with the spindle,

Ordinary inverter standard drive is a 4-pole motor, the greater the number of poles of the motor, the greater the rated current, the motor pole number is the frequency converter when the self-learning automatically set, in the vector control must be self-learning

Q:Laptop power adapter bad what is the phenomenon?

Either the power is bad or the machine on the power supply module is bad to repair service

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:Inverter principle eff23

The basic principle of the inverter The inverter is a device that converts the power frequency (50Hz or 60Hz) into AC power of various frequencies to realize the variable speed operation of the motor. The control circuit completes the control of the main circuit, and the rectifier circuit converts the alternating current into direct current and DC Circuit rectifier circuit output smooth filter, the inverter circuit will reverse into the DC power.
