Q:Laptop adapter
The first of the power to be large, not recommended to use the second to replace the other 90W adapter size are similar, but if the computer is not installed when the battery, 65W can also be used, as long as the interface on the Oh
Q:What is the working principle of high voltage electrodes and frequency converters?
High-voltage inverter is the input power supply voltage above 3KV high-power inverter, the main voltage levels are 3000V, 3300V, 6000V, 6600V, 10000V and other voltage levels of high-voltage high-power inverter High voltage inverter from high - low - high; low - high; high - high points.
Q:Inverter principle eff23
Low-voltage general-purpose inverter output voltage of 380 ~ 650V, the output power of 0.75 ~ 400kW, the operating frequency of 0 ~ 400Hz, its main circuit are used to pay straight to pay the circuit. Its control has gone through the following four generations. 1U / f = C sine pulse width modulation (SPWM) control mode is characterized by simple control circuit structure, low cost, mechanical properties of hardness is better, to meet the general requirements of the smooth transmission speed, has been in various fields in the industry Widely used. However, this control mode at low frequencies, due to the lower output voltage, the torque by the stator voltage drop is more significant, so that the maximum output torque reduction.
Q:What are the AC motor speed control methods? What are the characteristics of each
1, the frequency converter: smooth, according to the need to adjust the speed, is the future direction of the development of AC motor; (FM) 2, star, triangular connection conversion, generally in the larger motor start star start, triangular operation, Starting current. (Magnetic pole pairs) 3, there is a two-speed, three-speed motor, an increase of the winding, the main change in the stator winding connection to change the speed. (Change the number of pole pairs) The speed of change has two factors: magnetic pole logarithm, frequency
Q:Pump frequency converter instantaneous restart and restart the problem
Inverter speed: Based on the advantages of speed control, energy saving and reliable operation, the frequency converter has gradually replaced the traditional variable speed, electromagnetic speed and voltage regulation. In the introduction of PWM flux vector control of the inverter a few years later, the end of 1998 and the emergence of DTC control technology inverter. ABB's ACS600 series is the first generation of DTC technology using the inverter, it can open the ring speed and torque for accurate control, and dynamic and static indicators have been better than PWM closed-loop control indicators. Direct torque control to measure motor current and DC voltage as input to the adaptive motor model. The model produces a set of precise torque and flux actual values ​​every 25μs. The torque comparator and flux comparator compare the actual values ​​of torque and flux with the reference values ​​for torque and flux to Determine the optimal switch position. It can be seen that it is through the torque and magnetic flux measurement, instantly adjust the inverter circuit switching state, and then adjust the motor torque and magnetic flux, in order to achieve the purpose of precise control.
Q:What is the adapter?
Easy to join the Electronics (China) Co., Ltd. to sell the type of adapter and the purchase of different adapters:
Q:Inverter with 2.2KW 6 pole motor. 1 minute 8 times reversing often burn the motor, how to solve. For the 2 pole 4KW motor is the same.
1. Change to servo drive and servo motor. Should be frequent no problem. 2. Or in the machinery to find a way to let it repeatedly change.
Q:On the laptop power adapter problem
Notebook power adapter matching the principle of the principle is: the input voltage to meet the requirements of the domestic exchange is 220V; output voltage and the original with the same output current must be greater than or equal to the original adapter output current, your future output current is less than the original will appear Power from time to time unexpected shutdown caused by increased data loss, the battery charge is not easy to rush to cause the battery aging process, the other adapter long-term work will increase the heat caused by increased safety risks.
Q:If it is 8-pole variable frequency motor, enter the motor nameplate parameters in the inverter input for the 4 pole can?
If the control accuracy is not high, then you can use the ordinary control. Since the choice of the inverter, it is best based on the motor nameplate to set parameters to ensure the stability of the motor running
Q:2 pole 0.75 kW motor can increase the speed through the inverter?
if the 4-pole motor to rise to 2-pole motor frequency, The frequency of the motor rises to about 100 Hz, which is easy to implement for the frequency converter.
