Q:Can the four motors be tuned to 2900 rpm?
You have to look at what is the load, and look at the motor bearing can not bear 2900 turn, if the line, then under normal circumstances are possible. Only to the speed up to the motor rated speed above, the motor output torque is reduced.
Q:Is the motor having a variable frequency motor and a variable voltage motor?
According to the way to start talking about a variable frequency motor and variable voltage motor
Q:Quartet of the TA, TC terminals have positive and negative?
The TC terminal has no positive and negative poles, which are passive programmable relays
Q:How does the variable frequency motor output torque at very low frequencies?
Low frequency, the motor torque is relatively low, generally VF inverter performance is good or bad, the price level reflected in this time. But there is torque to enhance the function, it will not move without moving. If no load can not start, check the motor card and other mechanical problems such as whether there is a problem.
Q:I have a 11KW-4 pole inverter, now with the 4KW-4 pole motor, what impact?
that is, the load is very heavy; caused by over-current burning inverter
Q:400w 6-pole motor should be equipped with much of the inverter?
Under normal circumstances, the market are sold on the inverter are based on the common 4-pole motor matching, when to match the 6-pole motor, the inverter to a large power level, which is 400W of the first-class power 0.75KW, and so on
Q:Pump frequency converter instantaneous restart and restart the problem
How the frequency converter works:
The frequency converter is a power control device that transforms the power frequency power supply into another frequency by the on-off function of the power semiconductor device. We are now using the inverter is mainly used to pay - straight - cross mode (VVVF frequency conversion or vector control frequency), the first frequency AC power through the rectifier into a DC power supply, and then convert the DC power supply frequency, voltage can be controlled AC power supply to the motor. The circuit of the inverter is usually composed of four parts: rectifier, intermediate DC link, inverter and control. Rectifier part of the three-phase bridge uncontrollable rectifier, inverter part of the IGBT three-phase bridge inverter, and the output for the PWM waveform, the middle of the DC link for the filter, DC energy storage and buffer reactive power.
Q:ASUS and dell notebook power adapter can be universal?
You do not indiscriminate use as well, we recommend that you contact the after-sales department for your service.
Q:Can the HP laptop's power adapter be universal?
Power supply low-voltage plug to the same, the voltage to the same, the current is greater than or equal to can be used
Q:ASUS power adapter Acer can use it
See whether the power adapter is suitable for notebook use, the following three conditions for reference:
1. The output voltage of the adapter is the same as that of the notebook.
