Q:What is the single axis of the inverter and multi-axis applications
The frequency changer mainly consists of rectification (alternating current direct current), filter, re-rectification (DC variable AC), brake unit, drive unit, detection unit micro-processing unit and so on.
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:The emitter E of the inverter inverter module and the AC output U are not directly connected together
Corresponding to a phase of the branch of the IGBT inverter module generally appear in pairs
Q:Laptop power adapter is broken, which brand is better domestic
I suggest to buy a compatible adapter on it, because My HP is the power adapter is broken, I spent more than 20 yuan to buy a city, the normal use of more than a year did not find the problem.
Q:Three-phase two-pole motor can be used to reduce the frequency of the inverter
Speed range adjustable, you can drop to any speed you want!
Q:Laptop power adapter in the ring is how is it?
Notebook power adapter generally use the switch circuit, the output 12V DC power supply, as the notebook DC / DC converter circuit power supply; In the switch circuit, the most prone to "creak" sound is the switch transformer coil (ringing), or high-voltage filter capacitor (fire);
Q:How to choose a Siemens inverter for a 5.5KW three-phase motor (2 pole)?
Power, voltage, frequency, and you can use torque sensors to measure torque
Q:Can the inverter stop intermittently during operation? If so, how to connect and set up
and the corresponding function of these terminals, you have to in the inverter Set up.
Q:Variable frequency pump pressure in the very low flow instability, why?
From the performance curve, the flow becomes smaller, the combination of pressure and frequency adjustment flow will only stabilize the flow at a small value, the pressure will be reduced, because the work point will move down.
Q:Laptop power adapter is used to do what
The laptop's power adapter is a device that converts 220V AC power from a power supply unit to a low-voltage direct current device for powering a laptop. Power adapter output low-voltage direct current into the computer, but also through the computer motherboard power circuit to further deal with, resulting in 1.8V, 3.3V, 5V and other sets of voltage for memory, CPU and other components to run; another power adapter to provide the power can also be related Charge control circuit to charge the battery for the laptop.
