What is the starting current of a 5o kilowatt motor

The rated current of the 50 kW motor is 85A, the direct starting current is calculated as 5 times the current is 425A, and the soft start is calculated as 3 times the current is 255A

35 square meters or more.

The cross-section of the wire refers to the cross-section of the copper core within the wire. The cross-sections of wires commonly used in residential buildings are:

5mm24mm2

6mm210mm2

16mm225mm2

35mm250mm2

Wait. Wire Selection Criteria:

1. Select copper core wires: wires and wires must first have good conductivity. There are copper core wires and other wires available in the market. Copper core wire is the most practical one for interior decoration. However, copper core wires are divided into several types, including large-radius copper cores and multi-wire copper cores.

2. Wires with strong load capacity: the electricity consumption in the family is sometimes large and sometimes small, and when it is the largest, we will turn on the TV, turn on the air conditioner, turn on the computer, turn on the lights, turn on the water dispenser, refrigerator, hair dryer, etc. If the load capacity of the wire is not strong, and the hot summer is not strong, it is easy for the wire to burn due to the high temperature, resulting in a fire.

3. Good waterproof performance. The appearance of some wires is easy to deform and crack, in case there is a water leak somewhere, then it will cause the electrical appliances to burn out, short circuit and even cause fire and personnel**. So be sure to have a hard outer skin and a good waterproof wire.

4. The main line must be a thick core. The so-called main line refers to the two main lines between the total power supply and all electrical appliances. The main line ratio must be made of thick copper core wire, because the main line is loaded with the charge of each electrical appliance, and the thick copper wire with excellent performance is required. Multi-core wires are available for bypass.

68A at 220V; 380V 40A.

According to the motor formula: i = p u then the motor current of 380v is equal to i = 15000, (is the root number of 3 power factor and efficiency are calculated respectively), if it is a 220v motor multiplied by, 380v motor starting current is times respectively, according to the motor is 15kw, to use a star delta starter, then the current of 1 3 is about 12 amps.

The rated current of the 15kw motor is 30A, and the starting current of the motor is 5-7 times of its rated current, so the starting current of 200A is normal, and the running current is only 15A? You should have a relatively small load, if you have a rated load, the running current should be about 30.

The motor is not suitable for long-term light load operation, and the operating efficiency and power factor are low under light load, and the power use efficiency is low. From an efficiency point of view, 75%-100% load is suitable.

<> If it is a kilowatt, with 380V electricity, the current is amperes, with 220V electricity, the current is amperes. If it is 6 kilowatts, with 380V electricity, the current is amperes, and with 220V electricity, the current is amperes.

Summary. Hello, I am glad to answer for you, the rated current of the 55kw motor is about 85A, the starting current should be above 250A, if the current limiter is used, it should be limited to more than 150A, otherwise it will cause the motor to start weakly, but the starting time should generally be controlled within 2 minutes. I hope my answer is helpful to you

Is it normal for the 555 watt motor load current to be 120?

Normal. Then this has no effect on the motor.

Didn't affect ha.
