280KW

Brief Introduction

Basic information of a 280 kW motor
A 280 kW motor is a high-power motor commonly used in industrial production and mechanical equipment. Its rated voltage is usually 380 volts, rated frequency is 50 hertz, speed is 1480 revolutions per minute, and output power is 280 kilowatts. The rated current of the motor can be calculated using the following formula
2. Calculation formula and specific values for rated current
Rated current=output power ÷ (3 × Rated voltage × Power factor
Among them, the power factor is generally around 0.8. Therefore, the rated current of a 280 kW motor is
Rated current=280000 ÷ (3 × three hundred and eighty × 0.8) ≈ 461 amperes
3. Application scenarios and precautions
A 280 kW motor is usually used in mechanical equipment that requires high power output, such as large compressors, water pumps, fans, etc. During use, it is important to pay attention to the following points
(1) The rated current of a 280 kW motor is 461 amperes, so when selecting cables and protective switches, it is necessary to match them according to the actual current to ensure safety and reliability.
(2) During use, it is important to regularly check the insulation and bearing lubrication of the motor to ensure its normal operation.
(3) For a 280 kW motor that operates for a long time, attention should be paid to heat dissipation to prevent motor overheating and damage.
In summary, the rated current of a 280 kW motor is 461 amperes. It is a widely used high-power motor that requires attention to safety, reliability, and maintenance during use.

The YE3 series high-efficiency energy-saving motor is suitable for driving mechanical equipment without special requirements, such as machine tools, pumps, fans, compressors, mixers, transportation machinery, agricultural machinery, food machinery, etc. The installation size of the YE3 series high-efficiency energy-saving motor is equivalent to the Y and Y2 series, and it is an updated product of the Y and Y2 series motors. The installation size and power level comply with IEC standards, the shell protection level is IP55, the cooling method is IC411, the continuous working system (S1), the junction box position is the top outlet, and the energy efficiency level is level 2. This series of motors uses cold-rolled silicon steel sheets as the magnetic material, and the efficiency meets the European EFF1 standard, which has reached the advanced level of similar products at home and abroad. It is an updated and upgraded product that the country will vigorously promote in the coming years.

The YE3-80-355 series motors comply with the new national standard GB/18613-2012. The YE3-80-355 motors adopt f-class insulation, and the YE3 series high-efficiency energy-saving motors have high efficiency, energy saving, high locked rotor torque, low noise, low vibration, and safe and reliable operation.. The rated voltage is 380V and the rated frequency is 50Hz. Y-connection method for power of 3kW and below; All other powers are connected in delta mode. The altitude at which the electric motor operates shall not exceed 1200m; The ambient air temperature varies seasonally, but does not exceed 40 ℃; The minimum ambient air temperature is -15 ℃; The average highest relative humidity in the wettest month is 90%; At the same time, the average minimum temperature of the month shall not exceed 25 ℃.
The electric motor has a shaft extension, which can be made into a double shaft extension according to user needs. The second shaft extension can also transmit rated power, but can only be driven by a coupling.
