Free end and the outer end of end cap 40 are fixedly installed with mounting ear 50.Mounting ear 50 include generally cylindrical ontology 51, from
The mounting portion 52 and the positioning region extended radially out on the length direction of ontology 51 that one end of ontology 51 extends radially outwardly
53.Mounting portion 21 is fixed to shell 10 using bolt, so that entire mounting ear 50 is fixed to shell 10 or end cap and becomes
The component part of motor.The circular mounting hole being adapted to the mounting portion 52, and the wall of mounting hole are provided on vehicle seat
Portion is provided with the location hole being adapted to positioning region 53.When installation, mounting portion 52 is inserted into the mounting hole of vehicle seat, and is positioned
Portion 53 is inserted into mounting hole, to make motor be supported entirely through mounting portion 52, and the radially installed position of motor passes through
Positioning region 53 is guaranteed and keeps, and will not rotate during the work time.
Fig. 6-8 shows the specific direct current generator of another kind according to the present utility model.Example in the motor and Fig. 1-3
Difference be shell.Specifically, the shell of motor is only configured with the first section and the second section, and eliminate third portion
Section.In other words, electric machine casing eliminates the ladder stop portion for installing magnetic cylinder.As replacing for the ladder stop portion
In generation, protrusion, or other stop configurations can correspondingly be arranged on the surface of internal cavity of the first part of shell.Due to eliminating
Part III, shell processing is more simple, has smaller axial dimension.Such structure is limited for axially mounted space
Use environment is particularly useful.
With continued reference to Fig. 4, the magnetic cylinder 20 of permanent magnet DC motor shown in Fig. 1 is shown, the magnetic cylinder 20 is for fixing
The stator of motor is constituted in electric machine casing 10.As shown, the magnetic cylinder 20 is integrated, injection molding or compacting are generallyd use
Process forming.The material of magnetic cylinder can be ferromagnetic oxide powder or anisotropy (or isotropism) cohesive neodymium iron boron magnetic particle and epoxy
Resin glue compression moulding, or by ferromagnetic oxide powder or anisotropy (or isotropism) NdFeB magnetic powder and PA or with PPS etc.
Thermoplasticity sizing material injection molding.
The periphery of magnetic cylinder 20 is formed as hexagon, connects with the inner surface of shell 10, and its inner cavity is cylindrical shape, for holding
Receive armature core 30.Magnetic cylinder 20 forms sequentially connected six magnetic poles and magnetizing, and in other words, magnetic cylinder 20 is divided into six magnetic
Pole, two adjacent magnetic poles have opposite magnetism.Specifically, each magnetic pole has along the middle position of arc chord angle
Maximum radial thickness, and there is the smallest radial thickness in the boundary with adjacent magnetic pole.The periphery in the section of magnetic cylinder 20
Every outside is formed by connecting by two adjacent facing directly for magnetic pole.
