FAQ

Is the speed of the motor controlled?
Armature for the cast steel made of cylindrical structure, which is connected with the squirrel cage induction motor shaft, commonly known as active part; Pole made of claw-shaped structure, mounted on the load shaft, commonly known as the moving part. The active and slave parts are mechanically free of any contact.
How to choose the right inverter?
2, constant torque load Constant torque load equipment requires low frequency inverter torque, dynamic response speed. Inverter 0HZ vector state, to 150% of the torque, to meet the needs of various conditions. For example: a dredger owner bucket inverter system, is a constant torque load, dual motor, and the load overload time is long, so the inverter configuration configuration to enlarge the two models of the G-type machine, while the power supply for the device Machine power supply, the inverter must be configured to input AC reactor.
Laptop adapter heat
Therefore, in the design and production of switching power supply, we must choose high temperature components. Of course, be sure to control the temperature of the power supply within the allowable range of the application environment. First, the conversion efficiency should be designed as high as possible, and secondly, to use the pressure drop is small, low loss of switching components, the third is to be thermal design, cooling area to be as large as possible, more than 100W switching power supply Should have a metal perforated shell, or add a cooling fan. The current notebook power adapter power is generally around sixty or seventy W, the use of high temperature plastic fire sealed package, the internal heat generated by the plastic shell mainly distributed out. Therefore, the power adapter surface temperature is still quite high, the maximum temperature or even reach about 70 degrees! Think of the inside of the adapter, it is not like the fire! So, when you use the laptop, try to place the power adapter in a better place to ventilate heat, do not put books and the like on the power above. As for the kind of hot feeling, do not have to worry about is the power, not angry strange!
Do you need to rectify before switching?
I used to do the frequency of the words to be rectified
Can different brands of laptop power adapters be generic?
First look at the specifications, voltage, power, current, are matched after looking at the interface, all the same can be used, or else the two are bad.
What is the difference between the collector and the emitter mode?
The emitter is very high, the base is mixed and the collector is the lowest
Lenovo g450 laptop power adapter specifications is what?
Lenovo G450 power adapter Model: ADP-90RH B LENOVO P / N: 36001681 Input: 100-240V ~ 1.5A 50-60Hz Output: 19V $ 4.74
Three motors, if coupled with the governor speed, is it necessary to add the inverter?
?Fourth, the electromagnetic speed: electromagnetic speed motor by the cage motor, electromagnetic slip clutch and DC excitation power. DC excitation power is small, usually by single-phase half-wave or full-wave thyristor rectifier composition, change the thyristor conduction angle, you can change the size of the excitation current.
