Specific embodiment
As shown in Fig. 2 a kind of shaftless and bearing prime mover outer rotor permanent magnet generator, by stator 3, rotor 2, support 1,
Protecgulum 6, the support 11, fastener 5 of fan blade 8, stator, fastener 10 are constituted, wherein, rotor 2, fan blade 8, flywheel 4 are rotating part,
Stator 3, support 1, the support 11, fastener 5 of protecgulum 6, stator, fastener 10 are stationary part, the effect of fastener be mainly by
Each part position as shown in Figure 2 couples with function.
As shown in figure 1, the rotating part of generator is fastened simultaneously with the rotary shaft 9-1 of the prime mover 9 for driving by fastener 9-2
Connection, rotor is distributed in outside the circumference of stator, the side wall transmitting torque of flywheel, while the side wall of flywheel is used as the one of cooling air channel
Part, protecgulum 6 is coupled with fastener 10 with support 1 with the stationary part of prime mover 9, after coupled with support 1 with fastener 5 again,
The support of generator stationary part and rotating part all is from prime mover 9.
As shown in Fig. 2 the rotor 2 of generator is made up of yoke 2-1, magnetic pole 2-2, flywheel 4, flywheel 4 and magnetic pole 2-2, magnetic
Yoke 2-1 is joined together, and yoke 2-1 is axially extending along flywheel outer rim, and magnetic pole 2-2 is arranged on yoke inner periphery, all of machine of rotor 2
Tool load is undertaken by the rotary shaft 9-1 of the prime mover 9 for driving, therefore engine block is without installation axle and bearing, reduces generating
The volume of machine, saves cost.
As shown in Fig. 2 after using outer rotor and shaftless structure, the support 1 of generator by shell 1-1, air outlet 1-2,
Circumscribing flange 1-3, inner casing 1-4, deep bead 1-5 compositions, shell 1-1, air outlet 1-2, inner casing 1-4 constitute a c-type region, will
Stator 3, rotor 2 are accommodated in the inner, and support 1 supports the weight and load of stator, while being moved with original with fastener 10 by protecgulum 6
The stationary part connection of machine 9, an entirety is formed by stationary part.
Some rib connections are set between shell 1-1, the inner casing 1-4 of the support 1 of generator, and the space between rib is
The inside and outside circle of support is joined together and has certain mechanical strength by air outlet 1-2, some ribs, while the space between rib
Air outlet as discharge air, plays a part of cooling support inner body (stator, rotor etc.).
Inner casing 1-4 and air outlet the 1-2 connection place of the support 1 of generator are in bell mouth shape, are with entering for whole system
Air port, can also be used to accommodate the part of other without prejudice to air intakes.
One circumscribing flange 1-3 is set on the support 1 of generator, for installing device necessary to other generators, such as
