Q:Speed regulation method of three - phase asynchronous motor
1, frequency control, with the inverter, power 2, change the magnetic pole logarithm, not feasible. 3, stator series resistance, energy consumption
Q:What is the laptop adapter
3, classification: according to the use of points (AC, such as home, office use AC are called AC; DC, such as the car, the aircraft are used DC are called DC); by the output voltage current (12V series, ASUS more commonly used, such as ASUS 12V3A; 15V series, TOSHIBA more commonly used, such as TOSHIBA 15V3A, 15V4A, 15V5A; 16V series, SONY, IBM more commonly used, such as SONY 16V4A, IBM 16V4.5A; Series, HP, such as HP 18.5V3.5A; 19V series, such as ACER 19V3.42A, TOSHIBA 19V3.42A; 19.5V series, such as DELL 19.5V3.34A, SONY 19.5V4.1A; 20V series, such as DELL 203.5A , LENOVO 20V3.25A; 24V series, such as APPLE 24V1.875A; 9.5V-24V series, such as Acharger ALS-185A35C).
Q:Why the notebook power adapter can not be universal
Third, the current is different Different brands of laptop power adapter current is not the same, for example: under normal circumstances IBM is 4.5A, Dell is 3.34A, Hp is 2.7A, Sony is 4.1A and so on. In fact, the same brand of laptop power adapter voltage and current are not the same. So, even if the same brand of notebook computers channeling with power adapter to confirm the voltage and current specifications.
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:Is the inverter output current proportional to the output torque?
The output voltage of the inverter is proportional to the frequency, which is to keep the motor flux constant, T = KIφ so the motor output torque is proportional to the inverter current.
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:Why G120 inverter to be equipped with 4-pole motor?
Not necessarily must be equipped with four-pole motor, 2 pole, 6 pole, 8 pole, 12 pole can be used. As long as there is no problem with attention to current matching. Because the amount of 4-pole motor is the largest, all the frequency converter, are based on 4-pole motor for the control model design.
Q:How to view the parameters of the notebook power adapter on your computer
The correct way to use a laptop power adapter 1. Try to avoid use in outdoor or harsh environments to prevent the adapter from being exposed or damp. 2. When you are not using the adapter, please unplug the power plug. Because, for a long time the power will let the adapter has been in working condition, will affect the end of life. 3. Although the adapter is a broadband operating voltage, marked from 100V-240V can be, but if the voltage is extremely unstable in the case of use, the same will cause damage to the power adapter
Q:What parts of the inverter composition
Frequency control technology is an important development direction of modern power transmission technology, with the development of power electronics technology, AC frequency conversion technology from theory to practice gradually mature. Inverter not only smooth speed, large range, high efficiency, start current is small, smooth operation, and energy saving effect is obvious. Therefore, the exchange frequency control has gradually replaced the traditional traditional slip speed, variable speed control, DC speed control system, more and more widely used in metallurgy, textile, printing and dyeing, smoke machine production lines and buildings, Water supply and other fields. However, due to the environment, the use of life and man-made operation and other factors, affecting the life of the inverter greatly reduced, while the use of a variety of failures have occurred. Here we are on the composition of the inverter and common problems and countermeasures and we discuss. Generally divided into rectifier circuit, flat wave circuit, control circuit, inverter circuit, and so on several major parts.
Q:Inverter ACS355 If the speed is outside the allowable range, how to set the limit value
Remember, 2001 this should be set to a negative number, set to a positive number of your speed will never be less than this value.
