TESTS OF A MOTOR. 173 found to start from approximately the same point, andthe total current will then be proportional to the totaltorque developed by the armature of the motor. The addition of this no-load current may be con-veniently carried out in the manner shown in Fig. 56,which shows the… … 10 0 10 20 30 Amperes in armature of generator.Fig. 56.—Comparison of shunt.
