- Q: Can the inverter stop intermittently during operation? If so, how to connect and set up
- One of these terminals is a common terminal, which leads from the common terminal and is connected to the corresponding terminal via the relay contact
- 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 motor series parameter setting of the inverter? If it is with the spindle,
- Ordinary inverter standard drive is a 4-pole motor, the greater the number of poles of the motor, the greater the rated current, the motor pole number is the frequency converter when the self-learning automatically set, in the vector control must be self-learning
- Q: Is the speed of the motor controlled?
- Slip motor is composed of ordinary squirrel cage asynchronous motor, electromagnetic slip clutch and electrical control device composed of three parts. Asynchronous motor, the stepper motor is used as the prime mover, and when it rotates, the armature of the clutch is rotated together. The electric control device is a device that provides the excitation current of the slip clutch excitation coil. Electromagnetic slip clutch, which includes armature, magnetic pole and excitation coil three parts.
- Q: Is the inverter output current proportional to the output torque?
- The output voltage of the inverter is proportional to the frequency, which is to keep the motor flux constant, T = KIφ so the motor output torque is proportional to the inverter current.
- Q: ASUS and dell notebook power adapter can be universal?
- One, not necessarily interchangeable. Need to compare the two adapter specifications to determine: 1, the books power adapter, there are 90W and 60W of the other, some products output voltage 19V and 14V of the other. "General" conditions, as long as the output power of the adapter is the same, the output voltage is the same (current may not consider), that is, their specifications are the same, you can directly substitute. 2, however, some foreign imports of products using 110V AC products, be careful to see clearly. 3, before the use of replacement, pay attention to observe if connected to the books of the power plug specifications are different, you can not directly insert. An interface adapter can be purchased. Can also be bad adapter plug, cut into the replacement adapter; Second, for example: 1, LITEON OEM products, parameters: input AC 100 ~ 240V 1.5A, output DC 19V3.42A. Rated output power 60W; 2, ASUS books supporting products, parameters: AC 100 ~ 240V 1.5A, output DC 19V 4.74A. Rated output power 90W.
- Q: How to choose a Siemens inverter for a 5.5KW three-phase motor (2 pole)?
- Power, voltage, frequency, and you can use torque sensors to measure torque
- Q: HP laptop power adapter how to open
- Adapter is broken is difficult to repair, for a barThe common method is to insert the blade into the gap in the middle of the adapter and then pry open
- Q: Short-term short-circuit converter DC link positive and negative will damage the inverter?
- This short circuit may not necessarily line, the inverter fan has three, one is no speed line, two are pulse, three are switching signal (this is very little, I only encountered several),
