Hi all,

I bought a permanent magnet dc motor form Como Drills UK. In the datasheet, it doesn't specify the armature resistance of the motor.

Can anyone tell me on how to calculate or measure the armature resistance of the motor please. Btw, the part no of the motor is RE 360.

Thank you very much.

If you have an accurate multimeter you can measure it. Another way to measure it is to stall the shaft of the motor and apply a small voltage (depending on the working voltage of the motor) across the motor's terminals. Measure the current and then find R=V/I.
