Measuring Armature Coil Resistance Set the meter to read ohms. Use the lowest range. Short the meter leads and record the value. This is the meter error value. Attach your meter to the two motor leads. Slowly turn the armature shaft and record values at 45° intervals. Average these values. Caution: Turning the armature shaft quickly, induces a current in the armature windings. This Will damage the meter.
Calculate the Stall Current E Ohm’s Law The basic Algebra of electronics I = R I = Current in Amperes E = Voltage R = Resistance in Ohms,
