Question

A 50Hp, 250v shunt motor moves a load that demands constant torque regardless of speed, the armature resistance is 0.04Ω, it is known that at full load the armature current is 160A

Ia1=160A

Ra=0.04Ω

a) If the flux is reduced by 10% of the initial value, will the magnitude of the armature current change?

Ia2=177.77A (NOTE: this is the answer of this part because just I need the part b )

b) Will the velocity value change? if so how much

Vt=250V
ra = 0.040hm
Ea
la =160A
Transcribed Image Text:Vt=250V ra = 0.040hm Ea la =160A
