One method of measuring resistance of the dc motor is by applying constant current while the motor shaft is locked so that it cannot rotate.Measurement can be taken at different shaft positions and compute the average of the measured values.
I request members to suggest whether the below idea can be used for measuring the resistance of dc motor:
Can it be possible to measure resistance of the dc motor by measuring the back emf and compute the resistance as per the formula below:
R =(V-Vb)/ I ( Where V is the supply voltage, Vb is back emf and I is armature current).
