Q:Inverter 0.2KW, the motor speed requirements down to 4 turn, the motor pole 4 pole. Can the drive drive the motor?
The first calculation: 4-pole motor, rated 1450r / min divided by 50HZ, then it is 29r / HZ. Your request is 4r / min, then the frequency of the inverter must be 0.1 less than 0.2HZ without load are compared Difficult to achieve. You can do the test, then you can try to play, if used to produce what is the best or reducer, so the inverter and the motor are good.
Q:Laptop power adapter is used to do what
The laptop's power adapter is a device that converts 220V AC power from a power supply unit to a low-voltage direct current device for powering a laptop. Power adapter output low-voltage direct current into the computer, but also through the computer motherboard power circuit to further deal with, resulting in 1.8V, 3.3V, 5V and other sets of voltage for memory, CPU and other components to run; another power adapter to provide the power can also be related Charge control circuit to charge the battery for the laptop.
Q:Servo control system can give the inverter signal,
but want two motor synchronization, it should be impossible, the converter does not reflect so fast, and the speed is not so stable.
Q:Speed regulation method of three - phase asynchronous motor
This is the two-speed motor 1 will be the UI VI WI connected to the third phase of the remaining joint empty at this time for the four 2 U2 V2 W2 connected to the other three junctions at this time for the two levels This is the angle - there are many binary speed In addition there are three-speed motor in this no longer introduced The number of variable pole pairs can be varied, but the more variable the number of logarithmic materials Like a two-speed motor with a set of windings Three-speed motor has two sets of windings So the current single-board frequency conversion speed up
Q:The notebook power adapter flashes
The problem is very simple Well, used to know all the notebook Kazakhstan, the adapter has a light above, if it is lit that is the problem of the notebook, the other side of the notebook above also have a power indicator, the notebook above prompted the red, but not Rushed, that is, the problem of the notebook, the computer problem, you directly on the factory is finished, if the insurance, and casually find a place to repair a Kazakhstan, 50-80 yuan if the adapter is bad, buy a generic You can, but also more than 50 points, the last time I bought a bad 58 yuan, ASUS GM, to help people in the end, to give you a shop to buy the adapter, you ask the owner of Kazakhstan to get,
Q:On the notebook power adapter output current and voltage issues
On the real virtual cable that adapter is rectifier filter output, no regulator, the notebook internal regulator, the adapter does not need to regulator. 3.25A is smaller than 4.5A, because the adapter has a power margin that can be used. Summer attention to touch the adapter surface is overheating. Conditional or buy a large number of good current.
Q:Laptop power adapter how to detect?
No load voltage, DELL plug more special, the middle needle no load measurement is no voltage, the outer ring outer house and the wall only 19.5V voltage
Q:My laptop can not use the power adapter, and can only use the battery, how is it ah,
1, laptop power adapter can not be used, first check the power outlet, plug, cable has no virtual state, if you can tell the normal equipment damage. Should be repaired. 2, the laptop battery must be charged through the power adapter or directly for the computer power, the power adapter is not missing, if you have experience can turn on the power adapter to see if the fuse is broken, try to update the fuse can be restored. If the integrated circuit is damaged, only updated.
Q:Three motors, if coupled with the governor speed, is it necessary to add the inverter?
First, the frequency control: the use of frequency converter to change the frequency of the motor stator power supply, thus changing its synchronous speed control method for all motors, which is the most advanced, the most widely used speed control method.
Q:What is the maximum speed adjustable for a 4-stage motor with a rated frequency of 50Hz / 60Hz?
Generally transferred to 60Hz, about 1800 rpm, although the maximum speed when the inverter speed adjustable to 135Hz, but the motor does not work. Bearing first to consider.
