- 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
- Q:What are the AC motor speed control methods? What are the characteristics of each
- 1, the frequency converter: smooth, according to the need to adjust the speed, is the future direction of the development of AC motor; (FM) 2, star, triangular connection conversion, generally in the larger motor start star start, triangular operation, Starting current. (Magnetic pole pairs) 3, there is a two-speed, three-speed motor, an increase of the winding, the main change in the stator winding connection to change the speed. (Change the number of pole pairs) The speed of change has two factors: magnetic pole logarithm, frequency
- Q:Laptop power adapter is used to do what
- Simply put the transfer into DC China's electricity is 220V AC, and the notebook is a direct current, the need for adapter to rectify, filter, regulator, and finally we need to form a direct current
- Q:Will the asynchronous motor pole change the number of speed control can also be combined with the frequency converter
- Of course, because the factors that determine the speed of asynchronous motor power supply voltage, frequency and motor pole pairs, so asynchronous motor speed can be achieved by changing the number of magnetic pole pairs, but this method needs to make a greater motor changes, Trouble, and change the number of poles can only achieve a single speed change;
- Q:What is the difference between the electronic governor and the frequency converter on the motor speed regulation?
- Probably the wider range of frequency converter applications! There is a more comprehensive protection of the motor on the inverter
- Q:Variable frequency conversion frequency difference characteristics based on,
- Pole is the pole pair. So that the synchronous speed has changed, you can speed, but can not smooth speed.
- Q:Inverter signal line analog 4-20mA connection positive and negative can be reversed?
- Analog input signal is particularly vulnerable to external interference, so the general use of twisted shield as a signal line; and wiring as short as possible, generally not more than 20 meters; if some use conditions are vulnerable to external serious interference, the analog signal Side need to add a filter capacitor or ferrite core.
- Q:Yaskawa inverter reported base blockade what is the reason?
- For example, when you stop the inverter, there will be a signal to the inverter, and then the inverter will base block, cut off the output, the motor will no longer work; when you need the inverter work, There is a signal to the inverter, the inverter to cancel the base blockade, it is normal work,
- 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:What is the IGBT? Our inverter IGBT fried,
- Popular point is a switch, give him the signal to continue in accordance with a certain order switch, the DC through the switch into a change in the exchange of alternating current, different frequency.
