PURPOSE: A method for measuring welding resistance and coil resistance of an armature is provided to measure a plurality of welding resistance and coil resistance with one measurement by increasing the number of main power source and the feedback power source applied adjacent commutator bars and by branching the circuit by electrically connecting a pair of the main power source and the feedback power source and to reduce the measuring time by measuring the feedback source power during the measuring electrical characteristics. CONSTITUTION: The method for measuring welding resistance and coil resistance of an armature includes the steps of supplying the main power source to commutator bars(B1 ¯ B10) and supplying the feedback power source to the adjacent commutator bars, increasing the number of the main power source and the feedback power source according to the number of commutator bars, and branching the circuit by electrically connecting a pair of the main power source and the feedback power source. The main current is supplied between B1 and B10 and between B9 and B10. The feedback current is supplied between B4 and B5 and between B6 and B5. And the circuit is branched into a circuit of B1-B2-B3-B5-B10 and a circuit of B9-B8-B7-B6-B5 after by connecting the B10 and B5.
