- Q: Surface grinder can add frequency converter, what are the advantages and disadvantages?
- Three frequency converter successfully used in NC machine toolsIn recent years, with the rapid development of the economy, the machine tool industry has also made rapid progress: it is reflected in the wide application of new technology and the obvious improvement of enterprise benefit. At present, the mainstream of consumption in machine tool industry is CNC machine tools. From the domestic and international market demand for CNC machine tools, after the NC machine tool market has the following characteristics: first, the economic CNC machine tools is the mainstream of the future products. Two, using new technology to reduce costs and improve product stability is the key to enterprise survival. Below we in the machine tool drive aspect uses the frequency control speed to say SAJ frequency changer in this profession application situation:
- Q: What's the frequency converter for? What does it look like?
- Frequency converter (Variable-frequency, Drive, VFD) is the application of frequency conversion technology and microelectronics technology, by changing the power supply frequency of the motor to control AC motor power control equipment. The frequency converter is mainly composed of rectifier (AC DC converter), filter, inverter (DC AC converter), brake unit, drive unit, detection unit, micro processing unit and so on. Inverter by internal IGBT drive voltage and frequency off to adjust the output power, the power supply voltage required to provide according to the actual needs of the motor, so as to achieve the purpose of speed, energy saving, in addition, there are a lot of protection drive, such as over-current, over-voltage, overload protection and so on. With the continuous improvement of the degree of industrial automation, inverter has also been widely used.
- Q: What does 0L1 stand for?
- The acceleration is generally overloaded during acceleration. Load inertia is too large, the inverter power is small, or the acceleration time is too short, and so on
- Q: How does frequency converter realize variable frequency speed regulation?
- The technique of alternating current control by changing the frequency of alternating current is called frequency conversion technology. The frequency converter usually uses the on-off function of the power semiconductor device to change the power frequency power to another frequency energy control device.
- Q: How much is the motor 90KW and the frequency converter selected?Colleagues suggest 110W?The cost will be higherIs it okay to choose 90KW?
- Should be able to, in the design of the inverter in consideration of the corresponding motor power matching. Choose a large capacity, a little waste Oh! Our company choose frequency converter is one-to-one correspondence, did not choose the large capacity.
- 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: What does "frequency" in household appliances mean?
- The air conditioner use frequency, enlarge the working range of the compressor, the compressor does not require intermittent running can be realized in cold and warm control, to reduce power consumption due to temperature changes, eliminate discomfort. In recent years, the new type of air conditioner has adopted brushless DC motor to realize variable frequency speed regulation, and its energy-saving effect is about 10% - 15% higher than that of AC asynchronous motor frequency conversion. In order to further improve the efficiency of the device,
- Q: What are the possible causes of frequency hopping overload?
- The meaning of inverter overload protection is that the output current of the inverter continues to exceed the rated current, but it has not exceeded the transient flow point, and the general duration is defined as 1min. The general overload constant torque converter is 150% 1min, variable torque converter is generally 110%120%/1min.
- Q: What do you mean by the capacity of the inverter and the capacity of the motor?
- That's not the case at all"Capacity" and "power" are essentially different. Usually we say that a large transformer capacity is how much KVA, but not to say how much KW, because the two are not the same thing
- Q: Electronic governor for single-phase motor speed control, frequency converter for three-phase motor speed regulation, what are their differences in speed control effect? How does the frequency converter adjust speed? Can you give me an example?
- The electronic governor is used to change the power supply voltage of the motor by controlling the turn-on angle of the thyristor, so as to change the characteristic curve of the motor to change the speed of the asynchronous motor. Its characteristics are as follows: the motor speed adjustment range of small, low speed motor with load capacity, speed is reduced, the motor torque decreases, not for constant load moment, when the speed is low, easy blockage phenomenon; generally applies only to fan type load.
