Specific implementation mode
The invention will be further described with reference to the accompanying drawings and examples：
As shown in Figures 1 to 6, a kind of magnetic steel of motor insertion method, includes the following steps：
1）Fixed rotor iron core：Rotor core 21 is placed in fixed position；
2）Mounting magnetic steel inserts tooling：Mounting magnetic steel inserts tooling, makes guide groove 12 and rotor core in magnet steel inserting tooling
24 face of magnetic slot on 21；
3）Magnetic pole is tested, magnet steel is inserted into：By magnetic steel of motor 31 by direction of insertion close to guide groove 12,12 top of guide groove is provided with
It is in the magnetic stripe 14 of 5 °~85 ° angles with 12 depth direction of guide groove, angle β is 45 ° in the present embodiment, 14 magnetic pole of magnetic stripe and motor
Magnet steel 31 presets pole orientation on the contrary, referring to that magnetic pole south poles are opposite in upper and lower orientation；Magnetic steel of motor 31 is close to guide groove 12
When, 14 lower section magnetic pole of magnetic stripe attracts magnetic steel of motor 31 down, if magnetic steel of motor 31 is attracted, magnetic steel of motor 31 is inserted into and is oriented to
Slot 12 illustrates the close anisotropy of magnet steel if magnetic steel of motor 31 is ostracised, then needs to be inserted into magnetic steel of motor 31 after exchanging direction
In guide groove 12.In the process that magnetic steel of motor 31 is inserted into down, magnetic steel of motor 31 is mutually exclusive after first attracting each other with magnetic stripe 14,
Cause magnetic steel of motor 31 more smooth, faster to the insertion process of guide groove 12.
4）Assembly is completed, tooling is unloaded：After magnetic steel of motor 31 is fully inserted into magnetic slot 24, magnet steel inserting tooling is unloaded
Under, the inserting of magnetic steel of motor 31 is completed.
In the present embodiment, the magnet steel of use inserts tooling as shown in Fig. 2, including circle identical with 21 size of rotor core
