Question

What is the rated power output in kw of a 8-pole motor designed to an iec 180l motor frame? (type in an integer. ).

Answer 1

Step-by-step explanation:

P=11 kW

Step-by-step explanation:

Given that

Number of poles= 8

I.E.C. 180L motor frame

From data book , for 8 poles motor at 50 Hz

Speed = 730 rpm

Power factor = 0.75

Efficiency at 100 % load= 89.3 %

Efficiency at 50 % load= 89.1 %

Output power = 11 kW

Therefore the rated output power of 8 poles motor will be 11 kW. Thus the answer will be 11 kW.

P=11 kW
