Q:The laptop's power adapter is too hot to do
Installed adapter heat should be no problem, I am now under the books, the fan mouth is very hot, the weather may be more and more hot it
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:Servo control system can give the inverter signal,
If two motors are to be synchronized, only two servomotors are used, one is set to spindle and the other is set to slave.
Q:Delta VFD-F frequency converter how to adjust the number of poles
Look at the 07 motor parameters, I VFD-F instructions need, then the mailbox sent
Q:What is the difference when using inverter frequency conversion ordinary motor and variable frequency inverter motor
First of all you have to understand the difference between variable frequency motor and ordinary asynchronous motor. 1, inverter motor cooling fan is not connected with the motor spindle, is independent, the fan rotation from the motor speed, to ensure that the motor cooling.
Q:Short-term short-circuit converter DC link positive and negative will damage the inverter?
the switch signal Is the fan running up after the speed line is low, this can be shorted. Pulse is every turn a circle, send two pulses to the speed line
Q:Yasukawa inverter reported bb code that is the reason why the base blockade?
This is not a fault! Only after the inverter receives the base block signal, it is not output!
Q: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.
Q:Jd1a-40 motor speed controller and how to connect the motor
Speed ​​control motor wiring method: 3.4.5 is the terminal of the tachogenerator (U / V / W) from the right-to-left order of 1.2 for the excitation coil (F1 / F2) terminal, from the extended end of the speed motor (electromagnetic clutch) Master 7 plugs on the air plugs (governor): terminal 1.2 for the 220v input, 3.4 on the speed of the motor on the excitation coil, 5.6.7 speed motor on the tachogenerator. Motor speed control method: The speed regulating motor is to change the speed of the motor by using the series, voltage, current, frequency and so on of the motor to make the thyristor voltage regulation method the best.
Q:How to make the motor speed (control speed), can not use frequency
In general, the torque generated by the motor is reduced with decreasing frequency (decrease in speed), and the reduced actual data is given in some frequency converter manuals. By using the flux vector control of the inverter, will improve the motor at low speed torque, even in the low speed area motor can also output enough torque. When the frequency converter to speed up to 60Hz frequency, the motor output torque will reduce the normal motor is designed to 50Hz (60Hz) voltage, the rated torque is given in this voltage range. So the rated frequency under the speed is called constant torque speed, the inverter output frequency is greater than 50Hz frequency, the motor torque to be inversely proportional to the frequency of the relationship between the decline. When the motor is running at a frequency greater than 60 Hz, the magnitude of the motor load must be taken into account to prevent the motor output torque from being insufficient. For example, when the torque generated by the motor at 100 Hz is about to be reduced to about 50 Hz, the torque is generated. So the rated frequency above the speed is called constant power speed.
