My machine is a 4 6 kW machine, so is he 4 kW or 6 kW

I think the labeling of your machine's power is a bit inappropriate; For example, a 7kw motor installed on a lathe, the power column of the sign can only indicate the power: 7kw, according to your machine labeling method, isn't it to be marked; Power: 5-7; 7-9？

It's a bit of a fool. Another example: a hydraulic press is equipped with a 25kw electric power machine, and the power column of the sign must be marked; The power is 25kw, but he has another column; Pressure 300t.

Such a label is correct, power and pressure are two different concepts, between them there is an electric power through the conversion of hydraulic pumps, cylinder systems, kilowatts into kilograms or tons, its labeling must also be in accordance with the rules, marked with an accurate pressure value, can not be marked with a pressure: 260-300;300—320。If this happens, there will be an equipment accident or a personal accident.

The change of network cable power is limited, and it is impossible to differ by 2 kilowatts, unless the line diameter is too small, resulting in insufficient power, which can not work, and even burn the line to cause an accident, which has nothing to do with labeling. Example 1 of the 7kw electric power, ideology it is 7kw, the lathe will be more or less after the speed change, that is because of the speed after the change, just like we can drive the car flat road can be high-speed, uphill must use low gear. The power transmission of the lathe depends on the gear mechanism, which is impossible to increase or decrease the power, so no matter what transmission mode your machine uses, it seems inappropriate.

It refers to the normal operation of the situation, the power fluctuates between 4-6 kilowatts, and the current consumed by the machine fluctuates during operation, so the power is also floating and there is no fixed value.

No, the load has collapsed means that it has reached the maximum value of the meter after reaching the cluster with kilowatts, the current is 30A, and the load of kilowatts should be at least 40A meter, and if the load is a motor or the like, it should be at least 50A or more.

The variable frequency power and the motor power are not equal to the heat, the parameters are not adjusted, the wrong adjustment will be heated, and the connection is not connected will also be heated, please ask a master to take a look at it and solve it, it is very simple.

When the frequency is high or low, the torque will decrease, so it is necessary to adjust the corresponding parameters such as moment balance to increase the torque.

What kind of machine, privacy machine?

Electric stoves and electric cherry blossom lanterns only need 4000 5000 generators.

Electric motors and refrigerators require 6000 8000 motors.

There can be no problem, the original 4 kilowatt 48V electric vehicle motor can be installed with a 6 kilowatt 48V gasoline generator, and the power is better than the motor power.

Yes, 6 is not bigger than 4, so more power is better.

Theoretically, the same power consumption is the same. But they rotate at different speeds:

The number of pole pairs of the 4-pole motor is p 2, and the synchronous speed is 3000 2 1500 rpm.

The number of pole pairs of the 6-pole motor is p 3, and the synchronous speed is 3000 3 1000 rpm.

The three-phase 4 kW-4 pole motor and the three-phase 4 kW-6 pole motor consume 100 kW h and 200 kW h respectively.

In the same power motor, the winding can be designed with different pole pairs (commonly known as the number of motor stages), that is, different speeds per minute to meet the needs of different occasions.

The synchronous speed of the 2-stage motor is 3000 revolutions per minute (the actual speed is about 2850 revolutions, the synchronous speed of the motor is 1500 revolutions per minute (the actual speed is about 1450 revolutions, the synchronous speed of the motor is 1000 revolutions per minute (the actual speed is about 950 revolutions, the synchronous speed of the motor is 750 revolutions per minute (the actual speed is about 700 revolutions, the synchronous speed of the motor is 600 revolutions per minute (the actual speed is about 580 revolutions).

At the same time, there are also multi-stage motors, that is, different stages are obtained according to the different connection methods of the lead wires.

Each consumes 4 kWh of electricity per hour. The power consumption is the same, but the rotational speed is different.

Theoretically, the power consumption should be the same!

Domestic reducer You can go to Senming to find a large factory in the round shed to order an orange spring Zetai! It is a reducer of the horizontal cycloid series! The speed ratio is 87, and the power is 4kw, and the No. 6 machine is used.

1. The total power indicates that there are kilowatts (kW) or horsepower (.). horsepower s-soup verb – increase horsepower 1kw = horsepower.

6PS is the meaning of 6 horsepower, and PS is the code name for metric horsepower.
