Road.
A kind of described New Marine propulsion motor, its cooling system by one with horizontal direction in 45 ° cooler,
Be arranged on cooler both sides ventilation blower and formed closing wind path cooling system housing composition, the air outlet of ventilation blower with it is cold
But system casing is concordant, air outlet and the end cap UNICOM of ventilation blower, cooler air intake surface and stator UNICOM.
A kind of described New Marine propulsion motor, its cooler, ventilation blower and cooling system housing overall package.
Or its cooler, ventilation blower and cooling system housing are bolted.
A kind of described New Marine propulsion motor, its out frame are connected with end cap by seam, bolt.
A kind of described New Marine propulsion motor, its end cap have with stator section identical profile, by some phases
Big gusset composition even, end cap top are provided with 45 ° of big chamfering, screwed hole and pin-and-hole are provided with the inclined-plane that chamfering is formed,
Seam is provided with the face being connected with out frame.
A kind of described New Marine propulsion motor, its out frame are formed by connecting by some small gussets, every piece of gusset
45 ° of big chamfering is all provided with top both sides, screwed hole and pin-and-hole are provided with the inclined-plane that chamfering is formed, is provided with the outside of gusset
Seam.
The beneficial effects of the invention are as follows：
1st, the appearance and size of propulsion electric machine is significantly reduced, particularly the size in height and width, facilitated
The master-plan in electric ship storehouse；
2nd, the oeverall quality of propulsion electric machine is alleviated, improves the torque density of the quality of motor；
3rd, the air-out area increase of motor, ventilating path shorten, reduce windage, improve cooling effect；
4th, the horizontal shock resistance of cooling system is improved.
In a word, compared with existing air cooling propulsion motor, the present invention is substantially reduced the size of motor, makes electric machine structure tighter
Gather, improve the cooling performance of motor, facilitate maintenance again, improve motor rigidity, wanted available for bulk, motor rigidity
Ask higher, maintainability good or the product of similar applications, there is important economic benefit and social benefit.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the structural representation of out frame of the present invention；
Fig. 3 is the structural representation of end cap of the present invention.
Each reference is：1-out frame, 2-rotor, 3-end cap, 3.1-big gusset, 4-cooling system,
