- Q: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.
- Q:How to view your own laptop power adapter is how much tile?
- There are signs on the power adapter, you look for sticky paper to write the voltage and current power. If there is no write power, the direct voltage multiplied by the current is the maximum power.
- Q:The laptop power adapter is hot
- Almost all of the notebook adapters have this problem, you do not have to worry about this. But do not know you can not tolerate what is the degree, if it is so hot that the adapter has a deformation, then it is recommended to immediately stop using, to the sale to the new
- Q: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.
- Q:Is the number of Amps of the notebook power adapter higher than the original number of security on the computer?
- Sure answer, no! Rest assured with it, but be careful not to buy the cottage goods, this on the computer and security is not good. good luck!
- Q:22kw.2 pole fan can use Fuji inverter?
- Definitely yes. 2-pole motor and four-pole motor difference is: the current is different, the speed is different, the torque is not the same,
- Q:In the official website to buy ThinkPad notebook, to the power adapter?
- Hello, generally there will be a power adapter with Kazakhstan, unless there is a special note bare metal
- Q:Do not the laptop directly connected to the power adapter?
- 2, due to the different configuration of the notebook, its power consumption also has a variety of specifications. Common for more than 60W, the configuration of some of the 90W, and the game adapter power in more than 120W, such as dual GTX1080 card crossfire Blue Star prototype, power consumption in more than 400W, the use of two 320W power adapter for its power supply;
- Q:What is the base blockade in the drive?
- Base blockade is to deal with ul or ce such a special application of security agencies means that when the parking limit action after the base blockade even if the program can not malfunction, relative to the emergency stop circuit more harsh they will directly disconnect the power
- Q:Why the number of motor poles increased, the inverter capacity will increase
- The number of poles of the motor is not directly related to the rated current, but the number of poles is larger and the power factor is lower and the rated current will be higher.
