Description
Technical field
The utility model is related to magneto technical field, especially a kind of permanent magnet synchronous motor of energy rapid cooling.
Background technology
In traditional permanent magnetic synchronous motor structure, permanent magnet, which is mounted on the rotor, to be rotated around stator and generates magnetic field.Usually
For motor the course of work in, casing internal will produce amount of heat, these heats are affected to the stable operation of motor,
Therefore it is mounted on fan in motor shaft tail end, heat is dispelled by fan effect.The radiator structure of existing permanent magnet synchronous motor,
All it is the heat emission hole of long trough to be opened up on the rear capping of casing tail portion, but only have these heat emission holes, it still cannot be more rapidly
Ground disperses a large amount of heat.
Invention content
The technical problems to be solved in the utility model is：In order to overcome the deficiencies in the existing technology, the utility model provides
A kind of permanent magnet synchronous motor that can quickly dispel casing internal work calories, ensure motor stabilizing operation.
Technical solution adopted by the utility model to solve its technical problems is：A kind of permanent magnet synchronous electric of energy rapid cooling
