FAQ

Please recommend a high performance laptop power adapter?

See what model you notebook ah, according to your power adapter voltage, rated current to match.

Will the asynchronous motor pole change the number of speed control can also be combined with the frequency converter

Of course, because the factors that determine the speed of asynchronous motor power supply voltage, frequency and motor pole pairs, so asynchronous motor speed can be achieved by changing the number of magnetic pole pairs, but this method needs to make a greater motor changes, Trouble, and change the number of poles can only achieve a single speed change;

Three motors, if coupled with the governor speed, is it necessary to add the inverter?

??Third, the cascade speed: Cascade speed refers to the winding motor rotor loop in the adjustable resistance to change the motor slip, to speed the purpose of the past, the most widely used.

Jd1a-40 motor speed controller and how to connect the motor

Third, cascade speed control method Cascade speed regulation refers to the winding motor in the rotor circuit in the adjustable additional potential to change the motor slip, to achieve the goal of speed. Most of the slip power is absorbed by the additional potential in series, and then an additional installation occurs, and the absorbed slip power is returned to the grid or converted to the energy. According to the slip power absorption application method, the cascade speed regulation can be divided into the motor cascade speed regulation, the mechanical cascade speed regulation and the thyristor cascade speed regulation situation, take the thyristor cascade speed regulation, Suitable for fans, pumps and rolling mills, mine hoists, extruders on the use. Fourth, winding motor rotor series resistance speed control method Fifth, the electromagnetic speed control motor speed method Six, hydraulic coupler speed control method This method is suitable for fan, pump speed.

How to disassemble the notebook power adapter

3, then open the shell of the power adapter, you can see the adapter circuit outside the package with a copper shield, with a knife to cut the shielding tape on the tape, and then use the soldering iron shield and the internal circuit board connected to the two Solder joints, you can remove the shield.

30 kW 6 pole frequency motor torque is how much

To know what is the use of ah, the inverter motor is the same with the ordinary motor, but to prevent the operation of a low speed plus a fan

Inverter problem

A: The inverter output 4 ~ 20mA (0 ~ 20mA), the analog signal can be directly connected to the measuring instrument, the daily design, installation, application are so, as long as the selection is correct, there will be no problem.

The laptop's power adapter can be used on a desktop computer

First of all, the desktop is the kind of power, is ups uninterruptible power supply. But relatively large, not directly inside the chassis. In addition, the storage capacity is limited.
