Basic principles of marine DC motors

Basic principles of marine DC motors

1. Electromagnetic torque equation Figure 1 is a schematic diagram of a shunt motor. It can be seen from the figure that when the power is turned on, the current If passes through the armature, while the current Ia passes through the shunt winding in parallel with 

Requirements for marine propulsion motors

Requirements for marine propulsion motors

The requirements for the propulsion motor are not only determined by the characteristics of the marine┬ápropulsion motor,┬ábut also the environmental conditions such as seawater, salt spray, mold, etc., and the tactical and technical conditions such as the influence of tilt, sway and impact, etc. when 

Features of marine propulsion motors

Features of marine propulsion motors

The ship’s speed and propulsion shaft power vary widely, and the ship’s requirements for propulsion motors determine the characteristics of propulsion motors. It is a multi-working-condition motor with high reliability, large capacity, low speed, high torque, high power ratio, and a wide range of power
