To solve the above-mentioned problems, the utility model uses following technical scheme:
The utility model provides a kind of large inertia motor counter weight construction, including shaft, stator rotor group, casing, clump weight
And flat key, the stator rotor group and the clump weight are mounted in the shaft, the stator rotor group and the counterweight
Block is all set in the inside of the casing, and the spindle portion is set to the casing internal.
The stator rotor group includes rotor core and stator as a preferred technical solution, and the rotor core is fixed on institute
It states in shaft, the stator is set to the outside of the rotor core, and the length of the stator is greater than the length of the rotor core, institute
It states stator and insulation film is installed beyond the part of the rotor core.
The clump weight is close to one end of the stator rotor group to the inside of the stator as a preferred technical solution,
Extend be equipped with extension, the extension be set to the stator exceed the rotor core part, the extension with it is described
Clump weight is integrally formed.
Further technical effect takes full advantage of the axial spare space and stator of shaft by the way that extension is arranged
Inner space, this makes it possible to obtain do not changing the counterweight that one third is promoted while the design of other components；Meanwhile it is such so that
Rotor c.g. is adjacent to motor leading portion bearing part, increases motor smooth running and reliability.
It is as a preferred technical solution, detachable connection between the clump weight and the shaft.
Further technical effect, detachable design can use the counterweight of different weight according to actual use situation
Block increases the flexibility of structure.
The clump weight is fixed in the shaft by flat key as a preferred technical solution, the shaft with it is described
The keyway to match with the flat key is provided on clump weight.
Further technical effect, flat key limits the axial movement of clump weight, so that motor is whole in the process of work
Body structure remained stable.
The one end of the clump weight far from the stator rotor group offers recessed along its circumferential direction as a preferred technical solution,
Slot.
Further technical effect opens up the dynamic balancing that groove is conveniently adjusted motor.
The effect of increase inertia can be realized by increasing clump weight in the large inertia motor counter weight construction of the utility model,
It is increased without lengthening integrated motor, in the case where identical inertia, reduces the overall volume of motor, thereby reduce motor
Manufacturing cost.
