Q:Can a power converter be used in a motor with small power?
If it is overloaded with constant torque, the vector control or DTC, then not power motor inverter below 1/4, otherwise the inverter to motor "modeling" is not accurate, easy to control and protection of the disorder is not perfect.
Q:What does "G" and "P" mean in the converter model?
General inverter said, "G" and "P" type refers to the inverter general type and fan pump difference, G type inverter applies to the general machinery class load, and P type is used in the wind or water pump.
Q:Where is the difference between soft starter and converter?
High voltage soft starter work in high voltage environment, the insulation performance of all kinds of electrical components must be better, and the anti-interference ability of electronic chip is stronger. When the high voltage soft starter is composed of an electric cabinet, the layout of the electrical components and the connection with the high voltage soft starter and other electrical equipment are also very important.
Q:Delta inverter fault output which parameter is set?
Overload overload fault include frequency overload and overload. The electric machine may be accelerated in short time, the DC brake is too large, the grid voltage is too low, the heavy load causes. Usually by extending the acceleration time and prolong the braking time, check the power voltage. The heavy load, the motor and inverter can not drag this may be due to mechanical load, lubrication is not good. The former must replace high power motor and inverter; if the latter want to overhaul production machinery.
Q:How to choose frequency converter?
1. the power of the inverter is selected according to the load power. How many power motors should be chosen for a multi power motor?. Size one is ok.2. frequency converter model, different uses, choose different frequency converter. For example, there are general frequency converter, fan, water pump dedicated inverter, a machine tool spindle dedicated inverter. Wait。
Q:Why does the frequency change when the frequency converter regulates the frequency?
Main flux of motorM = U/ (4.44*f*N)In the upper model, the U is the stator voltage, that is, the output voltage of the inverter, f is the frequency, and N is the stator winding turn number.N is a constant.Obviously, when the frequency changes, if the voltage is constant, then the flux will change.The iron core of the motor is nonlinear, and when the flux changes, both too large (saturated) or too small (weak magnetic) is detrimental to the motor.Therefore, when changing the frequency, the voltage is changed, and the constant value of U/f is kept, so that the magnetic flux can be kept unchanged.
Q:At the base block Yaskawa inverter is what reason?
Garbage in Yaskawa signal board on the small line contact oxidation, look good, this is a kind of weak signal, and for safety relay is not the safety loop at high levels in a small line short circuit, 1000 Yaskawa A factory is shorted for a long time have blocked the oxidation base
Q:What are the differences between the two quadrant and the four quadrant of the inverter?
Simply put, the two quadrant ordinary inverter can only drag the motor forward or reverse. Work in one and three quadrants. The kinetic energy of the motor idle time can only be wasted. (of an electric motor)
Q:What does the brake unit on the inverter mean?
In order to digest this part of the energy, the transducer consumes the energy of the feedback current through the resistor.If the inverter is more advanced, this part of the current can also be sent to the call back network through the controlled rectifier bridge. There's no braking resistance.
Q:Synchronous operation of two inverters,
The boss to the electronic parts store, a duplex potentiometer, resistance and frequency converter converter on you as well, so that the original line after the line on the inverter came up to double the potentiometer, ah, ah ah Wang simple to score
