Q:The inverter is running independently
Principle of operation The main circuit is to provide asynchronous motor to the frequency conversion power supply part of the inverter, the main circuit of the inverter can be divided into two categories: voltage is the voltage source of the DC converter for the exchange of the inverter, DC circuit filter Is a capacitor. Current type is the current source of the DC into AC inverter, the DC loop filter is the inductance. It consists of three parts, the frequency power supply is converted to DC power "rectifier", absorbing in the converter and the inverter voltage ripple "smooth circuit." The basic composition of the rectifier unit: the fixed frequency of alternating current converted to direct current. High capacity capacitance: store converted energy. Inverter: high-power switching transistor array composed of electronic switches, the DC into different frequency, width, amplitude of the square wave. Controller: According to the set program work, control the amplitude of the output square wave and pulse width, so that superimposed as an approximate sine wave AC, drive AC motor.
Q:What is the number of parameters of the motor frequency of the Siemens inverter?
It is best to provide the model of the inverter Oh!
Q:What are the types of power adapter used in notebooks?
With the increasing popularity of notebook computers, the power requirements have increased. In addition, because the battery capacity (or density) increased, charging requirements also increased - so the laptop computer power requirements have doubled. However, larger and / or hoter power adapters are not an attractive option for millions of users who carry laptops around the world. Attractive is to have a compact, but instantly charged laptop adapter. Of course, it will not produce heat, and will not cost too much. In recent years, the development of electronic products has not increased the hope in this regard, and whether the future revolution can be achieved is still a pending issue. We also want to use a laptop adapter that can be used globally without the need for a 110/220 volt operating voltage selector switch - so the laptop adapter must be designed for truly universal line voltage operation. At the same time, regulators and OEM expectations also play a role.
Q:What is the characteristic of the variable pole speed method?
Third, cascade speed control method Cascade speed regulation refers to the winding motor in the rotor loop into the adjustable additional potential to change the motor slip, to speed control purposes. Most of the slip power is absorbed by the additional potential in series, and the additional device is used to return the absorbed slip power to the grid or to convert the energy. According to the slip power absorption and utilization, cascade speed can be divided into motor cascade speed, mechanical cascade speed control and thyristor cascade speed form, the use of thyristor cascade speed, which features: The process of the slip loss back to the grid or production machinery, the higher efficiency; device capacity and speed range is proportional to the investment province, for speed range in the rated speed of 70% -90% of the production machinery; Device failure can be switched to full speed operation, to avoid shutdown; thyristor cascade speed power factor is low, the greater the impact of harmonics. This method is suitable for use in wind turbines, water pumps and rolling mills, mine hoists, extruders. Fourth, winding motor rotor series resistance speed control method Winding asynchronous motor rotor series into the additional resistance, so that the motor slip increase, the motor running at a lower speed. The greater the resistance of the series, the lower the motor speed. This method is simple and easy to control, but the slip power is consumed in the form of heat. Is a level of speed, mechanical characteristics of soft.
Q:I have a 5.5 kilowatts of 4-pole motor, want to pass through the inverter, slow down to 130 per minute use, eliminating the need for speed,
wo recommendations, the first, the use of vector control of the inverter, you are expected to run the frequency of about 5Hz, this time, ordinary V / F inverter output torque may be small, not necessarily meet the requirements, of course, if it is High-end imported inverter, the problem should be small, with the domestic vector inverter, the frequency can also be full torque output;
Q:Three motors, if coupled with the governor speed, is it necessary to add the inverter?
 Fifth, the hydraulic coupler speed: hydraulic coupler is a hydraulic transmission device, generally composed of the pump wheel and turbine, when the pump wheel in the prime mover driven under the rotation, in which the liquid is driven by the blade and rotation, in the Under the action of centrifugal force along the outer ring of the pump wheel into the turbine, in the same turn to the turbine blades to thrust, to drive the production machinery operation. Through different hydraulic (lubricants and turbines) to achieve speed.
Q:Can the laptop power adapter be generic?
Output voltage, current, interface can be used as well.
Q:Does the inverter set the number of poles to match the number of poles of the motor?
The number of motor poles corresponds to the speed of the motor, the number of poles is not set when the speed of the control error, in the high speed requirements of the transmission is not allowed.
Q:Can the inverter be used to control the speed of the DC motor?
The inverter can be used to control the speed of the DC motor. Inverter control DC motor is to control the DC motor. Inverter is the application of frequency conversion technology and microelectronics technology to change the AC power frequency and effective voltage power control equipment. The frequency converter is usually used to control the AC motor. Inverter at work can change the AC power frequency and effective voltage, another point of view, is the inverter in the control output (injected into the controlled device) AC frequency, but also control the output of the effective power. A DC motor is a rotating electric machine that converts DC power into mechanical energy. DC motor coil in the current must be in accordance with certain changes (commutation) can be rotated, according to the principle of commutation DC motor can be divided into brush and brushless motor two categories.
Q: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.
