Fan, but its heat dissipation effect still cannot fully meet requirement, especially in the higher use occasion of some environment temperatures, merely
It is acted on by radiator fan, it is difficult to which really casing internal temperature lowers.
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 water-cooling permanent magnet synchronous motor that can preferably improve heat dissipation effect.
Technical solution adopted by the utility model to solve its technical problems is：A kind of water-cooling permanent magnet synchronous motor, packet
It includes casing, the drive end bearing bracket for being fixed on casing front end, the rear end cap for being fixed on casing, traverse casing and the motor by bearing support
Axis, stator and rotor, stator are fixed on casing inner wall, and rotor includes the permanent magnet that outer diameter face is fixed in iron core and insertion,
The iron core is fixed on motor shaft, and the radiation air for being fixed on motor shaft rear end is equipped in rear end cap and the space synthesized by casing
Fan, have in the casing around casing circumferentially around cooling water channel, the cooling water channel both ends be connected separately with into
The mouth of a river, water outlet.
Preferably to improve the flow effect of cooling water, the cooling water channel is circumferentially disposed around casing in the shape of a spiral.
The utility model has the beneficial effects that：The utility model is on the basis of original radiator fan, by casing
Wall opens up cooling water channel, is acted on by the cooling water circulated, to further improve motor radiating effect, is conducive to electricity
Machine stable operation in a high temperauture environment.
