Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described:
As shown in Figure 1-2, left shell 2 is arranged on motor rotary shaft 1 left end, left rotor 3 right side and right-hand rotation by bearingSon 6 left sides are pasted with left rare earth permanent magnet block 4 and right rare earth permanent magnet block 7 respectively, and the endoporus of left rotor 3 passes through driving key with electronicMachine rotating shaft 1 cylindrical coordinates to be installed；Stator 5 is arranged between left rotor 3 and right rotor 6, the upper part of stator 5 and left shell 2 andRight shell body 8 is fixing to be connected；It is equipped with positioning spigot on the right side of left rotor 3 and the left side of right rotor 6, connects ring set 9 solidSurely it is enclosed within positioning spigot, left rotor 3 and right rotor 6 are linked together；Band radially air channel rotary transformer seat 10 passes throughBearing is arranged on motor rotary shaft 1, and rotary transformer assembly 11 is arranged on band radially air channel rotary transformer seat 10, rotationTurn transformer cover 12 screw to be fastened on rotary transformer assembly 11；The external diameter of boring ratio motor rotary shaft 1 in described right rotor 6Greatly, between the endoporus and the external diameter of motor rotary shaft 1 of right rotor 6, circular radiating vent passages 100 is formed；Described right rotor 6And between right shell body 8, form heat dissipation channel A101；Heat dissipation channel B102 is formed between described left shell 2 and left rotor 3；A described left sideHeat dissipation channel C103 is formed between rare earth permanent magnet block 4 and stator 5；Heat radiation is formed logical between described right rare earth permanent magnet block 7 and stator 5Road D104；The left side of described band radially air channel rotary transformer seat 10 forms heat radiation with the junction, right side of right shell body 8Passage E105；Described left shell 2 is provided with some louvre F106；Described right shell body 8 is provided with some louvre G107.
Operationally, outside cold air enters motor from heat dissipation channel E105, through circular radiating vent passages 100,Respectively from heat dissipation channel A101, heat dissipation channel B102, heat dissipation channel C103, heat dissipation channel D104 take away motor stator and rotor producesRaw heat, eventually passes the louvre F106 on housing, louvre G107 and is discharged by hot-air, thus by continuous with the external worldGround air heat exchange circulation makes electric motor temperature reduction.
