Why do you install these things? Our factory has 380220 points. Then we plant in addition to high voltage motor, the other are 380 of the motor, then what's the use of these two things?
The main function of the transformer is to change the voltage, and to solve the problem of voltage magnitude (amplitude, RMS)The main function of frequency converter is to change frequency and solve the problem of voltage and frequency.The main application of frequency converter to motor is to adjust the speed of motor by adjusting frequency. Because the speed of the motor is related to the frequency of the power supply. Can play a role in energy saving.
Asynchronous motor is the torque between the current flowing through the motor flux and rotor as a result of the interaction, at rated frequency, but only if the voltage will reduce the frequency, then the magnetic flux on a large magnetic circuit saturation, the motor will be seriously burned. Therefore, the frequency and voltage should be changed proportionally, that is to say, to change the frequency, to control the output voltage of the converter at the same time, to keep the flux of the motor to be certain, and to avoid the occurrence of the weakening of the magnetic flux and the saturation of the magnetic flux. This control mode is mostly used in fans, pumps and energy saving inverters. The frequency changer changes the voltage, must change the frequency
The main function is to change the power supply voltage transformer, but also has some other functions, such as isolation transformer, is to play a protective role, he doesn't play the role of the transformer, the transformer that you are, in what place, or auto? Is it installed in the distribution panel? If you say is likely to auto start with the inverter itself is changing the power supply of the power frequency, when the electric motor is often used in some special occasions will be used! Because the most convenient way to change the speed of the motor is to change the frequency of the power supply!
What is the difference between inverter energy consumption braking and motor energy consumption braking?
The frequency changer changes the frequency of alternating current. The transformer changes the voltage.Take a closer look at the materials on the electrician.
