- Q:3.7KW inverter with 2.2KW 6-pole motor running to see the inverter shows the current is more than 4A, with the amount of clamp to 2.8A
- Two questions: 1, the inverter output waveform is not a standard sine wave, with the ordinary calorimeter measured value is completely not allowed. The output current of the inverter is the same.
- Q:Is the speed of the motor controlled?
- Change the external conditions, you can change the motor speed: 1. Change the number of pole pairs of the motor. (Multi-pole motor use) 2. Use the frequency converter to change the frequency speed 3. Winding motor rotor series resistance speed control. 4. Slip motor is to change the slip electromagnetic speed
- 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:The inverter flat rate transferred to 29, on the submersible pump to burn the coil ?!
- 1. submersible pumps are generally the problem, far away from the reflection voltage, the pump insulation breakdown, in particular, to better pump. 2. Distance away, the inverter and pump connection thicker. 3. Then on the output filter.
- Q:There is no inverter comes with simple PLC programming function
- The inverter is an AC speed control device, like DC speed control device, DC speed is to change the armature and excitation current, and it is the input AC through the internal circuit into DC, DC and then DC, the last DC AC output, this is the original 50Hz frequency AC can output other frequencies of alternating current, because the speed v is proportional to the frequency f, so you can set the frequency of the inverter to change the speed of the control motor. It does not have its own programming function. But there are servo drives, in fact, is a frequency converter, but can handle some of their own signals, usually from the servo motor on the encoder, and then control the servo motor to achieve precise control.
- Q:Laptop power adapter problem
- Second, the transformer This thing is not standardized production, the result is that even if the parameters of the same, the transformer to get another of this may not be compatible with the use of the explosion with the use of the cup like the situation, so we generally Stressed the original transformer.
- Q:Laptop power supply 20V 3.5A can use 20V 4.5A power adapter Mody, what impact?
- It's ok. As long as the voltage is appropriate on the line. Current value refers to the maximum current that can be output. How much depends on your computer. Or, with a big no harm, can only be better, if you can use a small, but a little longer charging time.
- 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:Notebook power adapter on how to look at power
- then the same formula can be used to calculate: power (unit: W) = voltage (unit: V) × current (unit: A). For example: the power adapter only identifies the output voltage is 20V, the output current is 4.5A, then we set a formula to know the output power is 20 × 4.5 = 90W.
- Q:Asus notebook power adapter how to open
- Hi respectful ASUS users The power adapter can not be disassembled, and if your machine's power adapter is faulty, you can go to the local service center for testing.
