Do you know what matters needing attention in the use of inverters?
Operation of the Vector Universal VFD LSD-B7000 at will during use will not only fail to perform its excellent functions, but may also cause damage to the inverter and its equipment, and may cause interference. Therefore, the following matters should be paid attention to during use. The inverter ...Read more -
What are the four common senses for the normal operation of frequency converters?
With the continuous improvement of industrial automation, frequency converters have been widely used. Such as air conditioner load, crusher load, large kiln calciner load, compressor load, rolling mill load, converter load, hoist load, roller table load, etc. Although the inverter has good anti-i...Read more -
What are the advantages and applications of inverter vector control?
1. Advantages of vector control system: The dynamic “speed response DC motor is limited by rectification, too high di/dt is not allowed. Asynchronous motor is only limited by the High-performance General Vector Inverter LSD-G7000 capacity, the multiple of the forced current can be achieved ...Read more -
What are the differences between vector inverters and general inverters?
The frequency converter is a kind of adjustable speed drive system. It uses variable frequency drive technology to change the frequency and amplitude of the AC motor’s operating voltage to smoothly control the speed and torque of the AC motor. The most common one is AC/ which has AC input a...Read more -

Frequency inverter typical applications
In most Chinese power plants, the induced draft fan of boiler furnace commonly runs at a constant speed with power frequency. A massive of energy is being wasted in the process of adjusting the wind quantity via the valve. The 200WM generator usually runs with peak shaving, with huge valley-to-pe...Read more -
LINGSHIDA shares the application of vector inverters in escalators!
The vector inverter technology is based on the DQ axis theory. Its basic idea is to decompose the current of the motor into D axis current and Q axis current. The D axis current is the excitation current and the Q axis current is the torque current. This could separate control the excitation curr...Read more
