Abstract
The utility model discloses a hand brushless generator and is to provide a hand brushless generator with short processing and assembly time, low loss and low cost. The hand brushless generator comprises a main shaft (1), a rotor block (2), a rotor ring (3), a rotor magnet (4), a stator (5) for winding and an oil-bearing (6); the stator (5) which is formed by the superposition of a plurality of pressing silicon steel sheets; the rotor magnet (4) is fixedly adhered to the rotor ring (3); the rotor magnet (4) is a ring integer magnet. The hand brushless generator can be widely used in the field of small electrical appliances.
Description
Technical field
The utility model relates to a kind of hand brushless generator.
Background technology
At present, in small household appliances such as hand-generation electric torch, generally use a kind of hand brushless generator to generate electricity.As shown in Figure 1, this hand brushless generator comprises main shaft 1, rotator seat 2, rotor steel loop 3, rotor magnet 4, the stator 5 that is used to wind the line, oiliness bearing 6, stator 5 is formed by stacking by some punching press silicon steel sheets, rotor magnet 4 fixedly is bonded on the described rotor steel loop 3, rotor magnet 4 is made up of 12 extremely end to end Nd-Fe-B permanent magnets of N, S, and 12 rotor magnet 4 usefulness seccotines are set on the endoporus of rotor steel loop 3.Because rotor magnet 4 is formed by 12, causes the part processing time long, loss is big, the processing technology complexity, and cost is higher; In addition, the part installation time is long, supplies such as glue large usage quantity, and part is also big because of the loss that assembling causes.
The utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of processing and installation time is short, loss is little, cost is low hand brushless generator are provided.
The technical scheme that the utility model adopted is: the utility model comprises main shaft, rotator seat, rotor steel loop, rotor magnet, the stator that is used to wind the line, oiliness bearing, described stator is formed by stacking by some punching press silicon steel sheets, described rotor magnet fixedly is bonded on the described rotor steel loop, and described rotor magnet is an annular whole magnet.
Described rotor magnet adopts the Nd-Fe-B permanent magnet manufacturing.
The beneficial effects of the utility model are: because rotor magnet described in the utility model is an annular whole magnet, make that the part processing time short, loss is few, processing technology is extremely simple, therefore cost declines to a great extent, the part installation time is short in addition, supplies such as glue consumption reduce, part reduces greatly because of the loss that assembling causes, therefore cost two degree descend, and performance of the present utility model and existing product remain unchanged substantially, so the utility model processing and installation time is short, loss is little, cost is low.
Description of drawings
Fig. 1 is the structural representation of existing hand brushless generator;
Fig. 2 is a structural representation of the present utility model.
Embodiment
As shown in Figure 2, the utility model comprises main shaft 1, rotator seat 2, rotor steel loop 3, rotor magnet 4, the stator 5 that is used to wind the line, oiliness bearing 6, the internal diameter of described rotor steel loop 3 is φ 38mm, the punching press silicon steel sheet that described stator 5 is 0.35mm by five thickness is formed by stacking, described rotor magnet 4 usefulness seccotines fixedly are bonded on the endoporus of described rotor steel loop 3, described rotor magnet 4 is an annular whole magnet, and described rotor magnet 4 adopts the Nd-Fe-B permanent magnet manufacturing.
Described rotor magnet 4 of the present utility model is the global formation manufacturing, has overcome existing product and has adopted the drawback that bonds together again after the multi-disc manufacturing, and the performance of product and existing product remain unchanged substantially.The utility model part processing time is short, and loss is few, and processing technology is extremely simple, so cost declines to a great extent, and the part installation time is short in addition, and supplies such as glue consumption reduce, and part reduces greatly because of the loss that assembling causes, so cost two degree descend.
The utility model can be widely used in the small household appliances field.
Claims (2)
