Q:Speed of 3000 r / min three-phase motor how to change its speed
Only the frequency converter to achieve the purpose of speed, because the rated voltage and frequency, the three-phase motor speed is determined by the motor within the pole pairs of pole number, but the frequency down, the speed decreases, plus a frequency converter, Can achieve the purpose of stepless speed regulation. The speed is calculated as: speed = (50 Hz * 60 seconds) / (number of poles / 2), the result is synchronous speed, the general asynchronous motor slightly lower than the synchronous speed. There is a change for the electromagnetic speed of the motor, but also to achieve the purpose of stepless speed regulation. If you have a fixed number of revolutions, you can consider buying a reducer and motor integrated, such as cycloid reducer, can also be installed between the motor and equipment reducer to achieve the purpose of deceleration.
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.
Q:On the notebook power adapter output current and voltage issues
This current is the maximum current value of the adapter output, Voltage matching, of course, can be charged. It is recommended to select an adapter with an output current value that is slightly larger than the original.
Q:Master Hello a machine requires 500 speed matching 6-pole motor frequency converter transferred to about 28HZ
6-pole motor synchronous speed of 1000 r / min, the actual motor speed is lower than the number, the actual speed is required to 500 r / min, then the motor and passive pulley diameter ratio of about 1: 1.6 or so, and then specific With the inverter to speed up to achieve the purpose, please refer to.
Q:Laptop computer about electricity no electricity, is the power adapter problem?
This situation is definitely not about what power off, if it is really about electricity no electricity, then your laptop is a one-time shutdown, rather than the screen flashing. I think this situation is more like a laptop screen lamp problem. Is unlikely to be a power problem. The screen flashes from the surface that there may be enough current. If the adapter can not provide enough current for the notebook, then the notebook will be over-current protection, which automatically shut down. You can find an adapter with the same output voltage as your adapter, the output power is greater than or equal to your adapter other adapter, if the situation remains the same, then it is certainly the problem of the lamp. But the inferred will not be a power problem.
Q:Laptop power adapter leakage
In fact, the adapter does not matter fake real goods, brand machine adapter are also purchased. According to my point of view, or I choose the words: casually buy one can, dozens of dollars on the line. In fact, the adapter is also worth tens of dollars, selling a few hundred dollars are also almost the same thing. Adapter is a small switching power supply, 100W or so, the value of that price.
Q:Motor a speed, the inverter will burn what is going on, the inverter is a large yuan
Note that the quality of the inverter is not ye, and now this situation is already very rare, it is recommended to replace the inverter brand, you can use Bosch Rexroth, the British Witten, Huichuan, Senlan, Haili Pu, Ou Rui, etc. Branded.
Q:What is the characteristic of the variable pole speed method?
Seven, hydraulic coupler speed control method The hydraulic coupler is a hydraulic drive, generally composed of a pump wheel and a turbine, which collectively referred to as a working wheel and placed in a sealed housing. The shell is filled with a certain amount of working fluid, when the pump wheel in the prime mover driven under the rotation, in which the liquid by the blade to promote the rotation, under the action of centrifugal force along the outer ring into the turbine wheel, in the same direction to the Turbine blades are thrusted to drive the production machinery. The power transfer capacity of the hydraulic coupler is consistent with the size of the relative filling fluid in the shell. In the course of work, change the liquid filling rate can change the coupler's turbine speed, made stepless speed regulation, which is characterized by: power to adapt to a large range, from several tens of kilowatts to thousands of kilowatts to meet the different power needs; Simple, reliable, easy to use and maintenance, and low cost; small size, can accommodate large; easy to control and easy to achieve automatic control. This method is suitable for fan, pump speed.
Q:Yaskawa inverter reported base blockade what is the reason?
Yasukawa compared garbage on the signal board on the small line of poor oxidation, and get like, this is a weak signal, and safety relays connected, do not use high-grade security circuit with a small line short, Yasukawa A 1000 factory is short for a long time after the oxidation of the base blockade
Q:ABB frequency converter and the difference between domestic frequency converter
Optical microscope mainly by the eyepiece, objective lens, stage and mirror composition.
