Propulsion motor

The utility model relates to a propulsion motor, in particular to a DC propulsion motor which is particularly applicable to propulsion motors for medium vessels and large vessels. The utility model comprises a rotor and a stator, wherein, the rotor comprises armature cores, armature windings, a radial ventilating duct, commutators and a rotating shaft; the armature winding which is distributed on the external circumference surface of the armature core is inverted V-shaped; the inverted V-shaped armature winding consists of an inverted V-shaped upper coil of winding insulation and an inverted V-shaped lower coil of winding insulation which are both of half-style structure and are embedded into an inverted V-shaped flume of the armature core. The rotor comprises two armature cores, two commutators and two sets of armature windings, the inverted V-shaped armature windings on the two armature cores are the same. The utility model has the advantages that: the radial electromagnetic force of the motor is reduced; t
