- Q:What is the difference when using inverter frequency conversion ordinary motor and variable frequency inverter motor
- 2, the ordinary asynchronous motor is the cooling fan and motor spindle connection, the motor speed determines the cooling fan speed, low frequency when the motor rotation is slow, so the motor temperature rise is the principle.
- Q:Inverter 0.2KW, the motor speed requirements down to 4 turn, the motor pole 4 pole. Can the drive drive the motor?
- Can, but this is a test product, the application does not try!
- Q:What is the output voltage of the laptop power adapter?
- Laptop power adapter output voltage, different brands may be different.
Adapter output voltage is not a unified standard, different models are not the same notebook.
The output voltage between 12V to 20V, 19V, 20V more.
- Q:ASUS power adapter Acer can use it
- 2. Is the adapter's output current consistent with the notebook's requirements? (Or a little bit of the current is also not.)
- Q:18: 5 kilowatts bipolar multi-pole pump motor with inverter
- With a 18.5kw inverter can ah such as ABBACS510 series
- Q:Laptop power adapter current is not the same alternative?
- because the output power is not enough, will burn. Note the voltage polarity!
- Q:What is the frequency converter used to do, why some motor with the inverter?
- Speed control, there are speed requirements of the place are in the inverter
- Q:Which machines are used for the frequency converter
- Frequency converter is widely used in the speed regulation of AC motor.Varameter speed 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, air conditioning and other fields.
