The inverter uses vector control in the occasions that require torque control, occasions that require low-speed and high-torque output, and occasions that require a wide speed regulation range beyond the rated speed, and require good control characteristics, etc. In fact, as long as it is V/F control, vector control can be used. The debugging requirements of vector control are a little more complicated than V/F control, and he is more strict in determining the motor model. That's all. The biggest feature of multi-machine parallel drive is that the load torque of each motor at the same time will not be the same. If it is a large vector control at this time, the ghost knows how the excitation component and torque component of each motor are distributed. . Judging from the sum of the power supply of the motor, it is a vector model of the motor, but it is not clear when it is converted to each motor. Although the equivalent model of the motor is the same, the control will change due to different forces. The basic idea of vector control is: imitating the speed regulation characteristics of DC motors, so that the speed of asynchronous motors can also be adjusted by controlling two mutually perpendicular DC magnetic fields. www.shuyitop.com; Tel/Fax: 0086-577-62840011 WhatsApp: 008613355775769 #inverter #forfrequencydrive #ACvfd #frequencyinverter #ZJSHUYI #Chinashuyi #variablefrequencydrive #threephaseacinverter #variablefrequencyinverter #3phaseinverter #achotsalefrequencyinverter #highvoltageacinverter

Maintenance requirements in the day-to-day operation of the frequency converter 1. Check whether the cooling system is normal, and clean the dust of the air filter. 2. Check whether the screws, bolts and other fasteners of the inverter are loose, and perform necessary tightening; for the parts with soldering and crimping terminals, check whether there is corrosion, discoloration, cracks, damage, etc., and also check the frame Whether the structural parts are loose, whether the conductors and wires are damaged, etc. 3. Check whether the connection of the control circuit board is loose, whether the capacitor is leaking, whether the lines on the board are rusted, broken, etc. 4. Check whether the filter capacitor is leaking and whether the capacitance is reduced. 5. Check whether the insulation resistance is within the normal range. www.shuyitop.com; Tel/Fax: 0086-577-62840011 WhatsApp: 008613355775769 #VFD #INVERTER #frequencyinverter #frequencyconverter #shuyitop #converter ...

Usually the soft start system is composed of softstart device, peripheral circuit and motor load. Therefore, the objects protected by the soft start system are also the soft start device, peripheral circuit and motor load. The purpose of protecting the soft start system is to ensure the safe and reliable operation of thyristor components, #softstarter equipment and circuits, and not damage or cause safety accidents under various abnormal working conditions. The premise of #softstarter protection is that the design of the soft starter itself should be correct. The thyristor components are correct and used correctly, the drive circuit and the control circuit are reasonably designed and matched with each other, so that the device can work in a good state. These measures are the basis for the safe and reliable operation of the soft starter. Only under this premise, can the devices, circuits, and equipment fail less and not fail from the inside, and the optimized system design should aim ...

Foreword: Inverter repairers must keep in mind that the inverter module and the drive circuit are strongly related to failures. When the inverter module bursts and damages, the drive circuit is bound to be damaged by impact. The damage of the inverter module may also be caused by the failure of the drive circuit. Therefore, whether it is a failure of the drive circuit or the inverter output circuit, it must be The inverter output circuit and the drive circuit are thoroughly inspected together. The power-on test of the main circuit must be carried out under the premise that the drive circuit is normal and can output six excitation pulses normally. Inverter power failure A 132KW inverter has a black screen fault. Part of the wire drawing machine stopped in the wire drawing workshop, and restarted production after half a month. As a result, the inverter went black after being powered on. It was judged that the switching power supply was faulty on the spot. The inverter was removed, and th...
