A multimeter supplies a voltage when it measures resistance. You must not supply another voltage when a multimeter measures resistance. The motor must not be connected to anything when you measure its resistance. Its resistance will be very low so you must subtract the resistance of the leads for the multimeter. The resistance of the leads are measured when the probes are shorted together.
Then use the measured resistance of the motor minus the resistance of the multimeter's leads as the R in the Ohm's Law calculation and use the voltage of your battery (22.2V) as the V in the Ohm's Law calculation. I is the resulting current: I=V/R.
