Q:Inverter 0.2KW, the motor speed requirements down to 4 turn, the motor pole 4 pole. Can the drive drive the motor?
The first calculation: 4-pole motor, rated 1450r / min divided by 50HZ, then it is 29r / HZ. Your request is 4r / min, then the frequency of the inverter must be 0.1 less than 0.2HZ without load are compared Difficult to achieve. You can do the test, then you can try to play, if used to produce what is the best or reducer, so the inverter and the motor are good.
Q:What are the differences and links between the soft starters and the frequency converters, and their respective principles and uses?
The soft starter is activated by adjusting the voltage and current, and the frequency converter starts the motor by changing the frequency of the power supply. The soft starter can theoretically smooth and gradually start the motor to the maximum speed. No impact current (ordinary start-up current is 6-7 times the rated current) The inverter is best suited for tap water and fans, etc. The soft starter is not suitable for everything except for heavy load start.
Q:Inverter with 2.2KW 6 pole motor. 1 minute 8 times reversing often burn the motor, how to solve. For the 2 pole 4KW motor is the same.
1. Change to servo drive and servo motor. Should be frequent no problem. 2. Or in the machinery to find a way to let it repeatedly change.
Q:Delta VFD-A frequency converter motor number of poles set
According to the actual needs of the motor To provide the required power supply voltage, and then to achieve the purpose of energy saving, speed control, in addition, the inverter there are many protection features, such as overcurrent, overvoltage, overload protection and so on. With the continuous improvement of industrial automation, frequency conversion The device has also been very widely used.
Q:How does the variable frequency motor output torque at very low frequencies?
1, to improve the slip of the inverter compensation coefficient 2, to improve the continuous lifting coefficient of the inverter, but the coefficient is too high there will be overcurrent. 3, with no sensor vector control can increase the motor output torque or encoder with the vector control can make the motor at low frequency to achieve the rated output torque.
Q:Is the laptop power adapter long-haul?
Oh, the power adapter is a transformer, we use the electricity is 220, after it will be converted into a suitable computer voltage, or notebook can not withstand 220V, so as long as the power inside the transformer will work, If you do not have a computer, it is best to unplug the plug on the power outlet, even if the computer has to pull out from the outlet, or will have an impact on the life of the adapter.
Q:The inverter control power is also the same, the pole is not the same as the motor 6 or 4 pole can be used?
Can be used, their rated current is not the same, the need to use the inverter over-current overload protection and other parameters for the corresponding changes.
Q:Laptop power adapter current is not the same alternative?
because the output power is not enough, will burn. Note the voltage polarity!
Q:Lenovo laptop power adapter side of the feet which is positive
Power adapter is a small portable electronic equipment and electrical and electronic power supply conversion equipment, generally by the shell, power transformer and rectifier circuit, according to its output type can be divided into AC output and DC output type; by way of connection Divided into wall and desktop.
Q:Can the laptop power adapter be generic?
Not common. Different computer adapter interface is not the same, and the voltage, current is not the same. If just the same, you can use, the voltage can also be used.
