91
armature current does not exceed 200% of the rated value or fall below the rated value. That is, the machine is to start with 200% of the armature current and as soon as the current falls to the rated value, sufficient series resistance is to be cut out to restore current to 200% (or less in the last step). The process is to be repeated till all the resistance is cut out.

21. In a Field’s test on 230V, 2hp mechanically coupled similar series motors, the following figures were obtained.

Sketch the power flow diagram for each operating condition.
23. A 230V DC Shunt motor, takes an armature current of 3.3A at rated voltage and at no-load speed of 1000 rpm.
