High-voltage frequency converter based on H bridge series units. High voltage inputs directly. In order to save energy, phase-shifting transformer inputs the low voltage on the second side to each power unit of H bridge and the output series of each phase and all power units connect so it has formed high voltage to drive the motor that. It’s a high-tech, green energy-saving product integrating advanced automatic control technology, high-power electric and electronic technology, fast and reliable fiber communication technology, high voltage technology and digital signal processing technology.

Q:B2b frequency how to speed
How does changing the power frequency to change the speed of the motor? When the motor is connected to the power supply to drive the normal operation of the load, at this time to change the power frequency, such as the current frequency down, the motor armature rotating magnetic field speed will decline, the rotor conductor cutting magnetic field speed decreases, turn from the induced potential , The rotor current decreases, the torque decreases, the load on the shaft does not change, the torque will be less than the load resistance torque, the motor rotor speed decreases, the rotor conductor cutting the magnetic field line speed increases, the rotor induced potential increases, the rotor current increases, The torque rises until it is equal to the load resistance torque, and the speed is smaller than the original. After stabilizing the work, the torque of the motor is the same as that of the original. (The motor torque is the same as the load torque, the load is constant and the motor torque is not changed)
Q:What is the frequency of `30 points
By changing the AC frequency of the way to achieve AC power control technology is called frequency conversion technology
Q:What is the difference between the collector and the emitter mode?
The emitter is very high, the base is mixed and the collector is the lowest
Q:Three sets of batteries (540V) DC power supply U / f inverter.
It is estimated that the battery should be string - and - series connection method, and then rectifier part of the converter (which may also be caused by the switch) is actually a series of diodes in series, positive and negative after the reverse is actually the battery is Negative shorts, resulting in burning, as to burn only one of the group of a few cells, it should be string - and - string and that group, because the parallel to bear it double voltage.
Q:How does the spindle drive system of the inverter realize the positive and negative control of the main pole?
The general inverter has an external terminal control and communication control two modes optional, select one of them can be completed ah
Q:11kw 6-pole motor can be used to adjust the inverter to 1800RPM?
First, the inverter is no problem, I used so much to meet your needs
But to see if your motor can run at high speed, or whether the load is small, the power to have a general amount of redundancy.
6-pole motor synchronous speed of 1000, to meet your use to be transferred between 2000 or 1900, that is to say the frequency converter output frequency to be transferred to 90 to 100HZ.
Constant torque load is no problem, but the fan torque load to be a small job.
Q:Siemens g120 inverter torque limit what is the meaning
Torque is a strain, the inverter can not actively control the output torque size, only according to the size of the load demand torque, the output of the corresponding torque.
Q:Oil-free vertical vacuum pump why a little negative pressure inverter on the torque limit
Here is not the inverter can solve the problem, you should first 220V single-phase AC rectifier for the DC (full-wave rectifier plus filter about 310 volts),
Q:The laptop's power adapter can be used on a desktop computer
First of all, the desktop is the kind of power, is ups uninterruptible power supply. But relatively large, not directly inside the chassis. In addition, the storage capacity is limited.
Q:Is the laptop power adapter high temperature normal? Is there anything else?
Normal, my power adapter is also very hot, generally ignore
