- Q: What is the difference between the electronic governor and the frequency converter on the motor speed regulation?
- Electronic governor is the use of control thyristor conduction angle to change the motor supply voltage, the motor characteristics of the curve down to change the speed of asynchronous motor. Its characteristics are as follows: the motor speed adjustment range is small, low speed when the motor load capacity is poor, the speed decreases, the motor torque decreases, not applicable with constant load, when the speed is low, prone to stall phenomenon; Applicable to fan load. Inverter speed is to change the frequency of the motor to achieve the AC asynchronous motor speed adjustment, speed adjustment balance, the motor load characteristics do not change with the speed change, suitable for load adjustment and constant torque adjustment. Excellent performance, but the cost is higher.
- Q: My Lenovo v450 laptop power adapter should be bad how to match?
- Lenovo V450 laptop power adapter is broken, the warranty period is not artificially damaged can be directly to the Lenovo aftermarket replacement adapter can be outside the warranty period to pay maintenance, it is recommended to use the original power adapter the best. Laptop charger (Laptop Charger), that is, laptop charger. The traditional notebook charger can only output a single voltage to a type of notebook computer charging, the industry called the traditional notebook power adapter for the single band notebook charger (mainly in order to distinguish between the universal notebook charger.)
- Q: What is the application of variable frequency speed control?
- In the second half of the 20th century, the power electronic devices from the SCR (thyristor), GTO (gate can be turned off thyristor), BJT (bipolar power transistor), MOSFET (metal oxide field effect transistor), SIT (electrostatic induction transistor ), SIT (Electrostatic Inductive Thyristor), MGT (MOS Control Transistor), MCT (MOS Control Gate) to today's IGBT (Insulated Gate Bipolar Transistor), HVIGBT (High Voltage Insulated Gate Bipolar Thyristor), Device To promote the continuous development of power conversion technology. Since the 1970s, pulse width modulation variable frequency (PWM-VVVF) speed control research has aroused people's attention. In the 1980s, the PWM model optimization problem, which was the core of the frequency conversion technology, attracted people's interest and made many optimization modes, in which the saddle-wave PWM mode was the best. The 20th century, the late half of the 1980s, the United States, Japan, Germany, Britain and other developed countries VVVF inverter has been put into the market and widely used.
- Q: What is the single axis of the inverter and multi-axis applications
- Inverter is mainly used for AC motor (asynchronous motor or synchronous motor) speed adjustment, is recognized as the AC motor the best and most promising speed control program, in addition to excellent speed performance, the inverter is also significant Energy-saving effect, is the enterprise technological transformation and product upgrading of the ideal speed control device. Since the introduction of China since the 80s of last century, the frequency converter as energy-saving applications and speed of process control more and more important automation equipment, has been rapid development and wide application.
- Q: ABB frequency converter and the difference between domestic frequency converter
- Both the eyepiece and the objective lens are convex lenses with different focal lengths. The focal length of the convex lens of the objective lens is smaller than the focal length of the convex lens of the eyepiece.
- Q: Can the notebook's power adapter be mixed?
- At present, the market sales of notebook power is generally 90 watts and 65 watts two, using integrated graphics, or configure the low-end notebook, usually 65 watts. Using the independence was, the configuration of high-end, or the game audio and video of this, are generally 90 watts. If the laptop's power adapter is damaged can not be used, it is best to repair the department as soon as possible to repair. If it is for emergency, before using the two adapters to check the output power and current and voltage are conceded, as the adapter input current and voltage is not the same, should be the general household voltage is 220V, so almost all of the notebook power The adapter is 100-240V ~ 1.5A words, as long as the output current and voltage values, and wattage equal, and then one is the same interface, you can mix. In general, the voltage is stable, the output wattage is the same, the notebook is basically no harm.
- Q: Inverter problem
- A: The inverter output 4 ~ 20mA (0 ~ 20mA), the analog signal can be directly connected to the measuring instrument, the daily design, installation, application are so, as long as the selection is correct, there will be no problem.
- Q: Who knows how the frequency converter works
- 2. flat wave circuit In addition, the ripple current generated by the inverter also changes the DC voltage. In order to suppress the voltage fluctuation, the inductor and the capacitor absorb the pulsating voltage (current). In general, the DC voltage of the rectifier is rectified and the DC voltage is rectified. General inverter power supply of the DC part of the main circuit in terms of margin, so eliminating the need for a simple capacitor filter smoothing circuit.
- Q: Is the laptop power adapter AC and DC?
- Most laptop power adapters can be used for 100 ~ 240V AC (50 / 60Hz). Basically, most of the notebook computers are external power supply, with a power cord and the host connection, which can reduce the size and weight of the host, only a very small number of models built in the host power.
- Q: What is the IGBT? Our inverter IGBT fried,
- Basically change the voltage, the voltage changes in accordance with the different frequencies, so that change the speed.
