Q:How does the variable frequency motor output torque at very low frequencies?

Low frequency, the motor torque is relatively low, generally VF inverter performance is good or bad, the price level reflected in this time. But there is torque to enhance the function, it will not move without moving. If no load can not start, check the motor card and other mechanical problems such as whether there is a problem.

Q:The laptop's power adapter can be used on a desktop computer

Desktop machine is called DIY it ~ is the assembly machine inside the motherboard graphics card hard drive memory What is the need for power supply every power to have a different interface

Q:The inverter flat rate transferred to 29, on the submersible pump to burn the coil ?!

The following describes the selection of the inverter Note: The inverter selection is mainly driven by the load characteristics and the actual motor current to set, in addition, there are the following precautions. 1, the environment: for some high temperature (higher than 50 degrees), high altitude (more than 1000 meters) of the application, the inverter selection should be appropriate to leave a margin to ensure that the inverter and motor life. 2, distance: the location of the inverter installation and drive the distance between the motor more than 50 meters, the frequency changer selection should cooperate with the reactor to reduce the carrier frequency. 3, a drag: a drive drag more than one motor, if the middle of the cable is too long, universal inverter selection will enlarge the use of a file, and each machine should be installed behind the fuse.

Q:Siemens g120 inverter torque limit what is the meaning

For example, you have 100kg of power, but you can send the power and you lift the weight of the object, if the object weight of 10kg, you can only use 10kg of power.

Q:Can different brands of laptop power adapters be generic?

First look at the specifications, voltage, power, current, are matched after looking at the interface, all the same can be used, or else the two are bad.

Q:6-pole motor, speed 8000 rpm, corresponding to the frequency converter output frequency is how much?

The synchronous speed of the motor is n = 60f / p P is the pole pair number, and f is the power supply frequency. The pole pair number of the 6 pole motor is 3. Therefore, f = n * p / 60 = 8000 * 3/60 = 400Hz.

Q:380V 2 pole motor can use the inverter?

Of course, the stator winding can be connected with concentric While enameled wire to be better, preferably 180 degrees or 155, and even dedicated enameled wire

Q:What is the principle and implementation of the inverter?

AC-DC is relatively simple We know that the diode has a one-way conductivity You can use this feature of the diode into a bridge So that the other end is always flowing into the other end is always out of the way it gets the voltage sinusoidal change of the DC If the need for smooth DC also need to be rectified Simple method is to connect a capacitor

Q:Notebook power adapter on how to look at power

Power and work voltage power adapter will be identified, you only need to distinguish between input and output on the line, the input refers to the utility power supply support, and now are generally 100V ~ 240V, so you can use in most parts of the world,

Q:Asus notebook power adapter how to open

if the power adapter is broken directly to the computer with a city on the line can not spend a few money back you can burn the computer is bigger to go to the computer The city took to repair and no one to repair to buy a very low price
