Circumference and be alternately arranged N poles and S poles.It should be noted that the quantity by the quantity of the magnet 31 of N poles and the magnet 31 of S poles
It is set as identical quantity.
Rotor assembly 4 is formed by the material being made up of magnetic.In the hoist engine 100 of this example, due to rotor set
Part 4, rope sheave 5, bear box 21 are integrally formed, therefore rope sheave 5 and bear box 21 are also identically with rotor assembly 4 by magnetic
Body is formed.However, being not limited to this, rotor assembly 4, rope sheave 5 and bear box 21 can also be respectively structured as independence
Component.Alternatively, it is also possible to form rotor assembly 4 by the material beyond magnetic, installed in the inner peripheral surface of rotor assembly 4 by magnetic
Property body form component, on the component install magnet 31.
Next, reference picture 4 and Fig. 5 are to the rotor assembly 4 in the hoist engine 100 of this example and the stationary state of magnet 31
Detailed construction illustrate.
Fig. 4 is the sectional view of the major part of the hoist engine 100 of enlarged representation this example, when Fig. 5 is enlarged representation braking
The sectional view of the major part of hoist engine 100.
As shown in figure 4, the fixed part 10 installed for magnet 31 in rotor assembly 4 turns into the outer concave towards radial direction
Sunken stage portion.Fixed part 10 has the stationary plane 10a and inclined plane 10b that magnet 31 is adhesively fixed by binding agent.Gu
Determine the step surface of the outside depression for the radial direction that face 10a is directed towards in fixed part 10.In stationary plane 10a with the phase of connecting portion 8
Anti- side, i.e. framework 2 (reference picture 3) side opens.
Inclined plane 10b is from the side of connecting portion 8 in stationary plane 10a, the continuous shape in side i.e. opposite with framework 2 (reference picture 3)
Into.Inclined plane 10b is with from stationary plane 10a to the direction in the axle center towards main shaft 3, to the direction away from connecting portion 8 continuously
Tilt.
In addition, magnet 31 has the opposed faces 31a opposed with inclined plane 10b and is bonded in stationary plane 10a adhesive surface
31b.Opposed faces 31a is configured in the side of connecting portion 8 when being fixed on fixed part 10.Moreover, opposed faces 31a is corresponding with inclined plane 10b
Ground tilts.In addition, inclined plane 10b contacts with opposed faces 31a, it is close in wedge-like.
In addition, in rotor assembly 4 with the end of the opposite side of connecting portion 8, the i.e. end of framework 2 (reference picture 3) side
On be configured with baffle plate 32.Baffle plate 32 is fixed on the end of rotor assembly 4 by fixing bolt 33.Now, in magnet 31 with
The opposite side of connecting portion 8, the end face 31b i.e. with opposed faces 31a opposite side abut with baffle plate 32.Moreover, magnet 31 is clamped
Between baffle plate 32 and the inclined plane 10b of fixed part 10.Thereby, it is possible to carry out the contraposition of magnet 31.Baffle plate 32 is not for example by
The nonmagnetic materials such as steel become rusty to be formed.
As shown in figure 3, when arrestment mechanism 6 is driven, rotor assembly 4 is in the presence of brake lining 6a towards radius
The inner side in direction, the i.e. axle center of main shaft 3 are pressed.Here, in order to realize the slimming of hoist engine 100, it is expected connecting portion 8
Thickness formed must be thinner than rotor assembly 4.Therefore, as shown in figure 5, rotor assembly 4 is from the corner of the side of connecting portion 8 towards radius side
To inner side deform.Now, the side shown in arrow P1 is received from the inclined plane 10b of fixed part 10 in the opposed faces 31a of magnet 31
To power.
