Summary. How to calculate the square of the line around the motor 1 kilowatt Hello dear, squared. A normal 1000-watt appliance needs to be equipped with a square copper core wire.

There are many varieties and specifications of wires on the market, and the difference is very large, usually household equipment or 4 square copper core wires, the latter is usually equipped with air conditioning sockets, and the actual purchase should take into account the logo of the wire, insulation layer and copper core quality and so on. 1000KW, 220V requires current 1000 220=, wire diameter, about 4 square meters. Hope it helps.

How to calculate the square of the line around the motor 1 kilowatt Hello dear, squared. A normal 1000-watt appliance needs to be equipped with a square copper core wire. There are many varieties and specifications of wires on the market, and there are many differences in the number of teasing wires, usually equipped with household equipment or 4 square copper core wires, the latter is usually equipped with air conditioning sockets, and the actual purchase should take into account the logo of the wire, the quality of the insulation layer and the copper core, etc.

It is how thick the copper wire used to wind the motor.

If it is not very long, you can choose two 3x185mm copper cores (laid in air) or two 3x150mm copper core cables and use them in a row. The basis is as follows: 380V 540KW current = 540KW (3X380V) = 685A, so the base ruler rock, the air can be used in parallel with two 3X180mm cables (353AX2 = 706A>685A); Two 3x150mm cables can be used in parallel for laying in the soil.

1. First calculate the rated current of the motor.

According to the formula for calculating the rated power of the three-phase motor: p=u i is the power trace crack factor of this motor, which is the efficiency of the motor, and the cos value of the domestic motor can be estimated in the actual estimation calculation, and you and i are the phase voltage and phase current of the motor winding, respectively), and the rated current of the motor is about 57A.

2. Select the appropriate cable according to the current size.

Choose the formula: ten down five hundred on two, Buzhou book two five three five five Meaning:

Below 10 square meters shall be wired according to 5A per square meter, more than 100 square meters shall be wired according to 2A per square, more than 10 (exclusive) and less than 25 square meters shall be wired according to 3A per square meter, and more than 35 square meters (inclusive) and below 100 square meters (exclusive) shall be wired according to 4A per square meter.

Therefore, it is necessary to choose a cable line macro of more than 10 squares.

Summary. Glad to be able to answer your questions.

The power of the motor is related to the current, basically 1000 watts can pass through the current is 2A, and then according to the power of the motor to calculate the current of the motor, and then according to the current to choose how many square wires to use. For example, a 4000 watt motor, its rated current is about eight amperes, then select the appropriate wire according to the current eight amps, and then the wires below the square are calculated according to one square with nine currents, and then each higher level will be reduced by one level, so that the 4000 watt motor is theoretically enough to have a square wire.

How to convert the motor power and how many square lines are used.

Glad to be able to answer your questions. The power of the motor is related to the current of the code, basically 1000 watts can pass through the current is 2A, and then according to the power of the motor to calculate the current of the motor, and then according to the current to choose how many square wires to use. For example, a 4000-watt motor, its rated current is about eight amperes, then select the appropriate wire according to the current eight ampere, and then the wires below the square are calculated according to one square with nine currents, and then each high Zheng Qi level will be reduced by one grade, so that the 4000-watt motor is theoretically enough to have a square wire.

How many square cables are used for 4 1,5kw motors, and the total length of the wires is about 5o?

Then you can choose a 4 square cable, which can ensure that the motor can run normally, and it is not hot, and it can also reduce the voltage drop.

1. Fan Haoshen can estimate the small motor below 20kw: 1) First estimate the rated current of the sock stool motor: The rated current of the motor is about twice the power of the motor; (Example:.)

8kw motor, rated current ie=8*2=16a)2)copper core cable can be estimated to withstand 4 amperes per square millimeter (e.g.: 8kw motor, 16a4a=4(mm2)))3)optional: 3*4+1* cable.

2. According to the estimated rated current of the motor, check the relevant manual, find out the current carrying capacity of the long-term allowable state deficit of the cable, and then appropriately increase the carrying area of the wire according to the conditions of cable laying and the ambient temperature.
