英文电机题,求指导!
A 50hp,250v dc shunt motor has an armature resistance of 0.06ohm and a field winding resistance of 50ohm.The no-load speed at rated voltage is 1200rpm.Neglecting armature reaction,what will be the speed of the motor when its input current is 200A?

一个50hp、250v直流励电动机具有电枢电阻的0.06ohm和一场的50ohm电阻。空速度是1200rpm额定电压。忽视电枢反应,会带来哪些马达的速度时,它的输入电流200A吗?
