Known motor power 160kW, distance 200m, how much aluminum cable to use, expert advice, urgent, thank you I didn't make it clear, four 40kW motors, frequency conversion starting line length of 200m?


185 square meters



The rated power of three-phase asynchronous motor is PN = 5kW, the rated speed is NN = 2910r / min, and the rated torque is TN=


The torque formula can be expressed as follows:
T=9550* (P/N)
=9550*(5/2910)
=16.41 N.M
Note: if the unit of P is w, change 9550 to 9.55 as follows:
T=9.55*(5000/2910)
=16.41 N.M
It can only represent the theoretical output torque of the motor



Rated torque of common three phase asynchronous motor?
What is the rated torque of 2-pole and 4-pole motor of 37KW? Is the torque of variable frequency motor with the same power and the same number of poles the same as that of ordinary motor? Is the higher the rated power, the greater the rated torque?


The rated torque formula of motor: TN ≈ 9550p / N2 unit - Newton meter where: TN_ Rated torque of motor (nm) P_ Rated capacity of motor (kw) N2 - rated speed of motor (R / min). The greater the power, the greater the torque. The torque of high-power motor with large number of magnetic poles is greater. The torque of variable-frequency motor is basically close to that of ordinary motor



Three phase asynchronous motor, rated power PN = 10kW, rated speed n = 1450r / min, starting capacity TST / TN = 1.2, overload factor λ = 1.8, calculate the rated speed


The rated current code is 20A
