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:3.7KW inverter with 2.2KW 6-pole motor running to see the inverter shows the current is more than 4A, with the amount of clamp to 2.8A

The inverter operates at constant speed below the base speed, and the output current of the inverter does not change as long as the load does not change.

Q:Old printing machine transformation, 37KW6 polar frequency motor with brake, inverter 55KW, now found running,

The frequency is too low or the brake gap is small

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:ASUS notebook power adapter can be universal? is it?

ASUS notebook power adapter is not universal, depending on the model, the output voltage and current requirements are different, select the battery and consistent adapter. Note: different brands of laptop batteries may be different, so do not use, through the laptop battery voltage and current comparison power adapter voltage and current to judge. If the voltage and current are roughly the same can be used.

Q:Inverter signal line analog 4-20mA connection positive and negative can be reversed?

Analog input signal is particularly vulnerable to external interference, so the general use of twisted shield as a signal line; and wiring as short as possible, generally not more than 20 meters; if some use conditions are vulnerable to external serious interference, the analog signal Side need to add a filter capacitor or ferrite core.

Q:Abb inverter s510 with water circulation pump why the motor fever. The motor is 2 pole

Motor fever is normal, ah, as long as not overheating on the line

Q:Servo control system can give the inverter signal,

Servo motor driver can give the inverter signal, with analog output to control,

Q:Please recommend a high performance laptop power adapter?

Power adapter can recommend you what model you get what model ah he is a standard can not just recommend

Q:Laptop power adapter is broken, which brand is better domestic

I suggest to buy a compatible adapter on it, because My HP is the power adapter is broken, I spent more than 20 yuan to buy a city, the normal use of more than a year did not find the problem.
