Q: Surface grinder can add frequency converter, what are the advantages and disadvantages?: SAJ inverter in the industry's specific applicationZhejiang Kanmen machine tool factory mainly produces all kinds of economic type simple NC machine, due to the higher failure rate of electromagnetic clutch speed regulation, realize VVVF system has more advantages, so using VVVF inverter to achieve the three. The details are as follows:

Q: Why does the frequency converter cause interference?: Method for solving interference caused by frequency converter:Adopt software anti-interference measures: specifically, the carrier frequency of the inverter is lowered through the man-machine interface of the inverter, and the value is reduced to an appropriate range. If this approach does not work, then only the following hardware anti-interference measures can be taken.Carry out the correct grounding: through the field investigation, we can see that the site of the ground is not ideal. The correct grounding can not only effectively suppress external interference, but also reduce the interference of the equipment itself to the outside. It is the most effective measure to solve the interference of frequency converter. Specifically, do the following two points:

Q: Not to say that the inverter speed is mainly down frequency, how can I see the frequency rise to 60HZ, so that the three-phase motor is not more than the rated speed?: When the high speed motor is driven by a transducer, the higher the higher harmonic is, the higher the output current value is due to the small reactance of the high speed motor. Therefore, the type selection of frequency converter used in high speed motor is slightly larger than the selection of ordinary motor.And if you want a long cable converter operation, this time to take measures to curb the influence of long cable on the coupling capacitor, to avoid the shortage of inverter output, so in this case, the frequency converter to enlarge the capacity of a file or install the output reactor in the inverter output.And for some special applications, such as high temperature, high altitude, at this time will cause the inverter derating, frequency converter to enlarge the capacity of a block.

Q: Where is the difference between soft starter and converter?: Are two completely different uses of the product. The inverter is used for the need for speed place, its output voltage and frequency change not only change; the soft starter is actually a regulator for motor starting, output voltage and frequency change not only change. Inverters have all of the soft starter functions, but they cost much more than soft starters and have a much more complex structure.

Q: The difference between soft starter and converter: The soft starter is just a thyristor pressure regulating device is simple to start the motor, the motor speed can not be normal, low price; inverter is the AC power supply voltage and frequency, can IGBT chopper can be used to start the motor, can also be normal speed, the price is relatively expensive

Q: Can the motor with frequency converter directly wave the insulation?: Is not possible because of the use of the insulating shake shake table while the output is DC but after conversion voltage value will exceed the rated voltage of the motor, the only way to test the motor winding phase to ground and insulation. But if the use of motor inverter drive, measurement of motor and inverter will not disconnect it, shake table issued a "high voltage" will be through the introduction of inverter winding inside, will lead to some components breakdown within the inverter a damaged, because although some internal components can be through the large current but the degree of pressure will be very limited so, in the insulating shake measure motor using frequency converter to the inverter and the motor is disconnected after, can make sure not to damage the transducer.

Q: Does the number of inverter settings differ from the number of motor poles, and does it affect the use?: Simple applications are unaffected. But if the high-end applications, such as elevators, cranes and other frequency converter using self-learning mode, the control performance will be affected. Common applications only affect the display speed of the inverter, and have no influence on the control equipment.

Q: What's the difference between universal inverter and fan pump converter?: Constant power load:The torque required by machine spindles and rolling mills, paper machines, and plastic film production lines is generally inversely proportional to the rotational speed, which is called constant power load. The constant power nature of the load should be in terms of a range of speed variations. When the speed is very low, the mechanical strength limit, TL can not be infinitely increased, at low speed into a constant torque nature. The constant power area and the constant torque area of the load have a great influence on the choice of transmission scheme. When the motor is in constant flux speed regulation, the maximum allowable output torque is constant, which belongs to constant torque speed regulation. While in the speed regulation of magnetic flux weakening, the maximum allowable output torque is inversely proportional to the speed, which belongs to constant power speed regulation. If the constant torque of the motor and the range of constant power speed are consistent with the constant torque of the load and the range of constant power, the capacity of the motor and the capacity of the converter are all the smallest, which is called "matching".

Q: What are the contents of frequency converter maintenance?: Operators must be familiar with the basic principles of inverter, functional features, with basic knowledge of electrical operations. Before checking and maintaining the frequency converter, the total power supply of the equipment must be cut off, and the inverter Chang lamp will be completely extinguished.

Q: Which brand of converter is better?: Shanghai Leinuoer recommended! Soft starter and frequency converter products Shanghai Leinuoer company, national key products, Shanghai famous trademark! People's Insurance Company of China quality assurance! Shanghai World Expo Shanghai reyrolle company supporting the project, the Beijing Olympic Games project,
