Q: Laptop warranty period is not over, the power adapter is broken, repair money?: The general adapter is only one year warranty. And even some power warranty for three months. Go to the official website of the notebook, see the specific information of the computer, which includes the computer parts of the specific warranty date and expiration date. If the warranty period, as long as the purchase of the invoice, you can go to aftermarket replacement or maintenance. Remember to bring an invoice, warranty card. It can not find the warranty card must find the invoice. General power adapter is new.

Q: Three-phase asynchronous AC motor speed control method: First, variable pole alignment speed method This method is to change the way to change the stator winding red way to change the cage motor stator pole to achieve the purpose of speed, the characteristics are as follows: With a hard mechanical properties, good stability; No slip loss, high efficiency; Wiring is simple, easy to control, low prices; A level of speed, large difference, can not get smooth speed; Can be used with the regulator speed, electromagnetic slip clutch used to obtain a more efficient smooth speed control characteristics. This method is suitable for production machinery that does not need stepless speed regulation, such as metal cutting machine tools, lifts, lifting equipment, fans, pumps and so on.

Q: What is the application of variable frequency speed control?: Generally used in the need for continuous speed control of the place. With the general exchange of motor than its advantages is able to continuously speed. DC motor, although also continuous speed control, but the price is expensive, the volume weight is too large.

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: Will the motor suddenly stop when the inverter is suddenly powered down?: but there are exceptions, such as head pump, water hammer effect after power failure will make the motor Reversal

Q: Laptop power adapter (no power supply, but indicator light): With a multimeter to measure the power adapter output interface voltage, no voltage is the adapter problem; a voltage is a notebook problem, and then decide how to do it. The adapter interface is less likely to be bad, but it does not exclude motherboard interface or power control chip problems. The former 50 yuan can get, the latter need a few hundred dollars.

Q: What is the frequency of `30 points: AC are frequency, China is 50 Hz, is in a second amplitude of 50 times. To change this frequency, it is necessary to use some electronic components to change the current frequency. General frequency conversion for the tributary motor speed more. So that some equipment can be stepless. Principle, see the first floor just fine, copy the more detailed.

Q: The inverter flat rate transferred to 29, on the submersible pump to burn the coil ?!: 4, high-speed motor: high-speed motor running process will produce a large number of harmonics, enhance the output current of the inverter, resulting in a lot of heat. Therefore, the inverter selection is also larger than the ordinary one gear. 5, explosion-proof motor: In some mines, oil extraction environment, the frequency conversion system is explosion-proof motor, the choice of inverter should use the explosion-proof function of the inverter, and the inverter placed in a safer place. 6, the degree of protection: for dust, wet applications, inverter selection should pay attention to its protection level. Or choose Ampang letter AMB inverter, the fan can also run in the water. 7, single-phase motor: When the scene using single-phase motor, the inverter useless. 8, variable pole motor: When the field using variable pole motor, the inverter selection should ensure that the maximum operating current should not exceed the rated current of the inverter

Q: Computer frequency changer to do cd frequency changer how points positive and negative: . In this circuit, the total capacitance is 6500 microfarads, the voltage is doubled.

Q: The emitter E of the inverter inverter module and the AC output U are not directly connected together: Pairs of modules are connected in a phase branch The phase output is derived from the neutral point between the modules
