Q: Motor nameplate on the standard 2P, I set the number of motor pole in the inverter, is set 2 or 4 pole?: n the motor pole, an Antarctic (S pole), an Arctic (N pole), calculate a pair of poles, the number of pole pairs is how many such "pairs" (S pole + N pole). 2 pole motor --- pole pairs 1 = P = 1,4 pole motor --- pole pairs 2 = P = 2, and so on.

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: Is the inverter output current proportional to the output torque?: When 50HZ or more, the voltage is not increased, the magnetic flux decreases. P = T * n / 9550, if the motor output torque does not change, the current will increase, the motor heat overload

Q: 6-pole motor, speed 8000 rpm, corresponding to the frequency converter output frequency is how much?: Such a high speed estimated motor can not reach, to increase the gearbox Specific algorithm: n = 60f / p P is the number of pole pairs, f is the frequency. The pole pair number of the 6 pole motor is 3. F = n * p / 60 = 8000 * 3/60 = 400 Hz.

Q: Delta VFD-F frequency converter how to adjust the number of poles: P148 look, this is to correspond to the number of poles of the motor, not to adjust the number of poles of the motor

Q: With the inverter control fan 37Kw4 pole with what model inverter: If the speed is not very high requirements, all the general-purpose inverter can be.

Q: What is the principle and implementation of the inverter?: How the inverter works: 1. DC can be converted into alternating current through the oscillation circuit 2. The resulting AC power is then boosted by the coil (in this case, the alternating current of the square wave) 3. Rectify the resulting alternating current to obtain a sine wave

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: The laptop's power adapter is too hot to do: Installed adapter heat should be no problem, I am now under the books, the fan mouth is very hot, the weather may be more and more hot it

Q: The inverter flat rate transferred to 29, on the submersible pump to burn the coil ?!: The following describes the selection of the inverter Note: The inverter selection is mainly driven by the load characteristics and the actual motor current to set, in addition, there are the following precautions. 1, the environment: for some high temperature (higher than 50 degrees), high altitude (more than 1000 meters) of the application, the inverter selection should be appropriate to leave a margin to ensure that the inverter and motor life. 2, distance: the location of the inverter installation and drive the distance between the motor more than 50 meters, the frequency changer selection should cooperate with the reactor to reduce the carrier frequency. 3, a drag: a drive drag more than one motor, if the middle of the cable is too long, universal inverter selection will enlarge the use of a file, and each machine should be installed behind the fuse.
