Specific embodiment
Specific embodiment one：As shown in Fig. 1 ~ Fig. 4：A kind of Space Facilities are assembled with the inorganic shell of separately-loaded magneto
Method, the inorganic shell assembly method of described Space Facilities separately-loaded magneto comprises the following steps：
Step one：Outside Space Facilities in the periphery ad-hoc location of stator core 1 of described separately-loaded magneto and described
The inner headed face of shell 2, uniformly offers multiple semicircle orifices 3 respectively, is opened on the periphery of stator core 1 of separately-loaded magneto
The quantity of multiple semicircle orifices 3 is identical with the quantity of multiple semicircle orifices 3 being opened on the inner headed face of Space Facilities shell 2, all described
Semicircle orifice 3 radius all same；
Step 2：The stator core 1 of separately-loaded magneto is sleeved on inside Space Facilities shell 2, and makes separately-loaded permanent magnetism
The periphery of stator core 1 of motor is in contact with the inner headed face of Space Facilities shell 2, makes to be opened in the stator of separately-loaded magneto
Multiple semicircle orifices 3 on 1 periphery unshakable in one's determination are corresponded with the multiple semicircle orifices 3 being opened on the inner headed face of Space Facilities shell 2,
The corresponding semicircle orifice 3 of each two constitutes a circular port；
Step 3：The Elastip pin 4 of one and circular port interference fit will be loaded in circular port described in each, by resilient key
Nail 4 eliminates fit-up gap, transmits torque.
Specific embodiment two：As shown in figure 1, a kind of Space Facilities separately-loaded permanent magnetism described in specific embodiment one
The inorganic shell assembly method of motor, in step one, is opened in the semicircle orifice on the periphery of stator core 1 of separately-loaded magneto
It must is fulfilled between 3 quantity and the pole slot number of separately-loaded magneto：The number of Elastip pin 4 is equal to the whole of unit motor number
Several times.
Specific embodiment three：As shown in Fig. 1, Fig. 3 and Fig. 5, a kind of space described in specific embodiment one or two sets
The inorganic shell assembly method of standby separately-loaded magneto, in step one, is opened in outside the stator core 1 of separately-loaded magneto
The position of multiple semicircle orifices 3 on disc must is fulfilled for particular requirement, i.e., one is must be alignd with tooth center line, the second is can not
Influence the close distribution of magnetic of separately-loaded magneto.
In present embodiment, the quantity and position distribution of semicircle orifice 3 are very crucial.If the presence shadow of semicircle orifice 3
Distribution of Magnetic Field is rung（Such as semicircle orifice 3 is arranged on magnetic flux path）, the close skewness of magnetic of motor will be made, and then produce
Additional moment is fluctuated, and motor characteristic is negatively affected.So, the quantity of semicircle orifice 3 is relevant with the pole slot number of motor, its institute
Position, it is necessary to be the position for f hardlying pass through magnetic flux.As shown in figure 5, opening up semicircle orifice 3 at the A of position, almost do not have to magnetic circuit
Have an impact；And be magnetic flux main path at position B and position C, it is unable to perforate.
Specific embodiment four：As shown in figure 3, a kind of Space Facilities separately-loaded permanent magnetism described in specific embodiment one

The external diameter of pin 4 is 3mm, and Elastip pin 4 is interference fit with the mounting means of circular port.Through test, separately-loaded after assembling
Magneto performance reaches expected requirement, works well.
Operation principle：
As shown in fig. 6, in traditional structure of permanent magnet torque motor stator component 7 for having casing 6, although the motor stator portion
Part 7 and casing 6 can be reliably connected, but casing 6 and equipment also need to be reconnected by modes such as flanges, virtually increase
The volume and weight of mechanical part is added.And a kind of Space Facilities of the invention inorganic shell assembling side of separately-loaded magneto
Method, as Figure 1-Figure 5, by the periphery of stator core 1 of separately-loaded magneto and the inner headed face of Space Facilities shell 2
Multiple semicircle orifices 3 are uniformly offered respectively, and loads interference in the circular port of the composition of semicircle orifice 3 being oppositely arranged in each two match somebody with somebody
The Elastip pin 4 of conjunction, realizes the reliable assembling of separately-loaded permanent magnet torque motor stator component, it is possible to stably transmit power
Square, is substantially reduced mechanical part volume, and then meet the lightness requirement of Space Facilities.
