This paper presents some critical questions considering particularly the design of DC propulsion motor for a submarine. Basic formulas for the calculation of bar to bar voltage distributing curve of DC motor commutator are derived and test-verified. The profound analysis of the choice and theoreorical calculation of armature winging is given. By using field-solving equation with finite element, the distribution of the field inside the motor is calculated and verified. The vibration and noise of the motor is also analyzed,calculated and verified, and there comes to the measures of improvement.
