Exercise 11) Motor data

 8e = √(T1^2*t1 + T2^2*t2 + T3^2*t3)/(t1+t2+t3)

T1 = 10 / T2 = 15 / T3 = 7

. t1 = 3 / t2 = 2 / t3 = 2

Pe = √(P1^2*t1 + P2^2*t2 + P3^2 * t3) / (t1+t2+t3)

Tn (motor) Tn = √(T1^2*t1 + T2^2*t2 + T3^2max*t3)/(t1+t2+t3)

Tn (motor) = Pn * 60 / 2 pi * nn

Nn=1400

Pn=3000

T3max = 14.625 * 10^!6
