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.
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.
My Lenovo v450 laptop power adapter should be bad how to match?
Lenovo V450 laptop power adapter is broken, the warranty period is not artificially damaged can be directly to the Lenovo aftermarket replacement adapter can be outside the warranty period to pay maintenance, it is recommended to use the original power adapter the best. Laptop charger (Laptop Charger), that is, laptop charger. The traditional notebook charger can only output a single voltage to a type of notebook computer charging, the industry called the traditional notebook power adapter for the single band notebook charger (mainly in order to distinguish between the universal notebook charger.)
The laptop power adapter is hot
My point of view: First: your laptop power supply in a small ventilation environment, resulting in poor heat dissipation, Second: the life of the power supply is 3-5 years, the gradual oxidation of electronic components and some of the aging components, resulting in no load and load a lot of power, Third: the battery close to each run, and then connected to the power, the power to the battery charger and notebook power supply, so the pressure is not hot strange.
How does the laptop's power adapter open
First put the power adapter on a clean desktop, with electric knife to the upper and lower cover along the edge of the gap slowly pry open, you can also use the hammer gently tapping the back of the electric knife, so you can turn on the laptop power adapter
What is the difference when using inverter frequency conversion ordinary motor and variable frequency inverter motor
2, the ordinary asynchronous motor is the cooling fan and motor spindle connection, the motor speed determines the cooling fan speed, low frequency when the motor rotation is slow, so the motor temperature rise is the principle.
What is the output voltage of the laptop power adapter?
Laptop power adapter output voltage, different brands may be different. Adapter output voltage is not a unified standard, different models are not the same notebook. The output voltage between 12V to 20V, 19V, 20V more.
Do you want to pay attention to the number of poles of the motor when selecting the inverter?
Inverter selection is mainly to see the power, and then pay attention to voltage problems. Finally look at what your motor is carrying.
