excitation current: I
- 4A
starting current: 1, = 180 A
st
Neglecting the no load losses and the saturation of the magnetic circuit, evaluate:
1) the amature resistance
Ra
2) the coefficent between e.m.f. and speed
K
3) the rated torque
(V/rad/s]
4) the rated efficiency
5) the speed when the motor delivers 1.5 T, (constant flux)
