On the notebook power adapter output current and voltage issues
This look at your computer is what brand if it is DELL may not be charged, some other brands can be used with some can not, if you can use the charge can then only charge time will be longer than the original power supply, the computer no effect, The current is not bigger than the original big line for a long time on the battery and the motherboard is not good!
Inverter ACS355 If the speed is outside the allowable range, how to set the limit value
2. Set the minimum speed allowed in 2001 MINIMUM SPEED.A positive minimum (or zero) defines two ranges, a positive range, A negative range. A negative minimum defines a speed range.
Speed regulation method of three - phase asynchronous motor
Change the number of pole pairs can be adjusted, in the way around the stator coil through the tap method can achieve two-speed. With the popularity of the inverter, three-phase asynchronous motor speed mostly with the inverter.
Motor nameplate on the standard 2P, I set the number of motor pole in the inverter, is set 2 or 4 pole?
n the motor pole, an Antarctic (S pole), an Arctic (N pole), calculate a pair of poles, the number of pole pairs is how many such "pairs" (S pole + N pole). 2 pole motor --- pole pairs 1 = P = 1,4 pole motor --- pole pairs 2 = P = 2, and so on.
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;
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
Three-phase motor, quadrupole asynchronous motor to 15rpm, the inverter output how many volt voltage? The 4 V
4 volts too little, at least tens of volts
Three-phase two-pole motor can be used to reduce the frequency of the inverter
If you need to be very slow, you can match a four-level motor ah, even more slowly with a reducer
